March 14th (3/14) is recognized around the world as Pi Day. A mathematical constant, Pi represents the ratio between circumference of a circle and its diameter. Typically represented as 3.14159, Pi (Greek letter “π”) continues infinitely without repetition or pattern, and can be calculated to more than one trillion digits past its decimal point.

The late Russian composer Igor Stravinsky once stated that “musical form is close to mathematics—not perhaps to mathematics itself, but certainly to something like mathematical thinking and relationship.” Building on this connection between music and mathematics, composer Michael Blake created a musical representation of what pi sounds like. Take a listen to hear what happens when you transpose the first 31 digits of the number pi into musical notes!

Assessment for Learning Practices

Wiliam (2011) states that professional development should focus on formative assessment, as a regular assessment-teacher-action cycle produces substantial increases in student learning. Teacher learning should include:

  •          understanding base knowledge of assessment practices.
  •          planning for implementation of strategies to respond to the assessment; and
  •          discussing instructional changes made and results on student learning.

Mathematics concepts build over time. While the focus for many provinces, school divisions, and schools is to increase student achievement in mathematics, that requires increased opportunities for students to be able to engage in grade level mathematics. This can only occur through opportunities to fill gaps in skills and understanding, which begins with identification of those gaps.

Gap Filling

Diagnostic Assessments

The first step in providing the opportunity for students to engage in grade-level mathematics is to identify which essential skills students are proficient at and which skills are barriers to engagement. A grade-level Pre-Assessment built on Essential Learning Outcomes is a tool that can help inform students, teachers, and parents.  A Pre-Assessment can be administered in its entirety at the beginning of the school year, or broken apart into concepts needed as pre-skills for each unit of study in the new year.

The structure of a continuum of Pre-Assessment Diagnostics is

Diagnostic Design

The questions in a Grade 3 Pre-Assessment are identical to those questions in the Grade 3 Post-Assessment. In addition to those core questions, concepts from Grade 3 are added. A suggestion is that the Post-Assessment would be administered in early May to allow for reteaching and redirection in order to best prepare students for the next grade level.

Not all concepts are included in these diagnostic assessments. Only those concepts that are skill based are included. For instance, the concept of Area is not included, as a student can understand the concept of area as an application of multiplication. Multiplication appears in the PreAssessment, but knowing the area of a rectangle does not.

These assessments are meant to be formative only. They are not meant to be a part of a reporting document, as they do not fully test conceptual understanding in the depth that curriculum requires. These are only a tool to know which preskills students are struggling with, and which preskills students are proficient with.

The diagnostics below were created by a working group from our Mathematics Community, including: Dulcie Puobi, Victoria MacMillan, Jennifer Brokofsky, Michelle Naidu, Lisa Bryden, Sharon Harvey, and Terry Johanson.

Grade 3 Pre-Assessment Grade 3 Post-Assessment
Grade 4 Pre-Assessment Grade 4 Post-Assessment
Grade 5 Pre-Assessment Grade 5 Post-Assessment
Grade 6 Pre-Assessment Grade 6 Post-Assessment
Grade 7 Pre-Assessment Grade 7 Post-Assessment
Grade 8 Pre-Assessment Grade 8 Post-Assessment
Grade 9 Pre-Assessment Grade 9 Post-Assessment
Grade 10 Pre-Assessment


The Kindergarten to Grade 2 Diagnostics Numeracy Assessments have a different format than the Grade 3 and up.  First of all these assessments are interview based and are intended to take no more than 15 minutes per student to administer.  Secondly, these assessments include a set of cards, a recording sheet and a rubric to support identification of students current level of understanding.

The Diagnostic Numeracy Assessments will not measure grade level concepts in enough detail to allow you to determine a report card grade. The outcomes that are represented on this diagnostic are skill based outcomes that fall into the strands of Number and Operations as well as Patterns and Relations and therefore, do not assess the mathematics curriculum in it’s entirety. For this reason, using these assessments for reporting purposes would be inappropriate and is not recommended.

The Kindergarten to Grade 2 Diagnostic Numeracy Assessments were created by a working group of teachers from our K-5 Mathematics Community including: Rhonda Wacker, Rosemary Vinet, Kelly Massier-Anderson, Elizabeth Phipps, Tracy Schnell-Persson, Wendy Macleod, Jennifer Hamon-Adair, Jodie Wachs, Dulcie Puobi, Jennifer Brokofsky, and Cassandra Neufeld

Gallery walks in a classroom mimic what would happen when you were visiting an art gallery or museum.  Most often, the visitor goes from picture to picture, or exhibit to exhibit trying to understand the artist’s meaning of the picture, or the purpose of the exhibit.  That is exactly what you hope to gain in a gallery walk in your classroom; students critically studying pictures or questions and making responses that would cause others to stop, think, and reflect.  Gallery walks are a great way to stimulate engagement, choice, and collaboration in the classroom.

There are different ways to do a gallery walk in a classroom.  Some Gallery walks are meant to encourage questions and curiosity, while others evaluate student understanding of concepts and unearth misconceptions. Used effectively, gallery walks can be used as an introduction to a unit or theme, as a concept attainment lesson, or as a way to gain peer feedback.  Obviously, gallery walks can be done in art, but they also lend themselves nicely to:

Most commonly, gallery walks are done with questions or pictures.  A gallery walk is a way to create movement for students while they dialogue.  Simply put, students get out of their desks and move through the room past the pictures or the questions.  Students can be recording thoughts, ideas, and answers on their own paper, or putting questions and thoughts up on the chart paper that has been provided so that others can enter into what has been recorded before they get to the gallery walk exhibit.  Depending on your outcome, gallery walks can be done individually, in partners, or small groups.  The number of exhibits can vary for a gallery walk, but realize the more stations the more time that is needed to complete the gallery walk.  Rotating through the exhibits can be a formal organized process where each station gets approximately 3-5 minutes, while other gallery walks can be more fluid allowing the students to choose how long they stay at a station.  Teachers can move through the room collecting observations to inform future lessons, or to stimulate conversations.  It is always important that at the end of the gallery walk that there is some type of synthesis of thought.

Key pieces to keep in mind when creating a gallery walk are:

  • It is most effective when the gallery walk is set up with open ended questions, or a focus that engages in higher order thinking skills
  • Clear step by step instructions and expectations of how the gallery walk should progress and how students should record their learning is important.
  • Arranging the room so that it is conducive to students moving through the different exhibits.IMG_1131

Math Trials

The opportunity to move the learning outside of the classroom can often serve to engage students in mathematics.  Math can come alive and be seen in the world beyond the four classroom walls.  One way to move math out of the classroom is with math trails.   Math trails are like scavenger hunts with a math spin to them.  As students move along the “course” they have opportunities to explore, observe, discuss, and connect with math in the world.

To get you started on designing your own math trails the NCTM has a great article called Designing Math Trails in the Elementary Classroom.  They have ideas on how to select a site, on- site activities, classroom follow through activities, and cross curricular connections.

The Canadian Math Trail is a great site for ideas about math trails created across Canada by teachers.

Subitizing is the ability to instantly see how many in a small collection of items without counting.  Dots on a die, shapes on a playing card, number of fingers held up on a hand, are all examples of subitizing in action.  In order to subitize successfully students need to see the whole as a collection of objects as well as the individual units.  Subitizing is considered to be a fundamental skill for supporting students understanding of number and ability to perform number operations.

In the primary years students should be given regular and consistent opportunities to subitize in order to build their skills, improve number sense and lay the foundation for future mathematical learning.  In kindergarten numbers to 5 should be focused on for instant recognition.  Once students are familiar with familiar representations of 1 to 5, larger collections can be used to encourage students part-part-whole thinking.   For example, on the card below students may instantly recognize a three and a four and then add the numbers together to know that there is a collection of seven dots on the card.

dot card

As the collections get larger students can be encouraged to use their estimation skills to think about “how many” and “how do you know”.  Our Saskatchewan Curriculum refers to this fundamental skill through several outcomes from Kindergarten to Grade 2:

  • Kindergarten- NK.2 Recognize, at a glance, and name familiar arrangements of 1 to 5 objects, dots, or pictures.
  • Grade 1- N1.2 Recognize, at a glance, and name familiar arrangements of 1 to 10 objects, dots, and pictures
  • Grade 2- N2.1 Demonstrate understanding of whole numbers to 100 (concretely, pictorially, physically, orally, in writing, and symbolically) by: 
    • representing (including place value)
    • describing skip counting
    • differentiating between odd and even numbers
    • estimating with referents
    • comparing two numbers
    • ordering three or more numbers.

This video is an excellent example of a kindergarten teacher who is using Quick Images to build on her students subitization skills, and create opportunities for mathematical conversation.

Reading in Mathematics?  When I was a student in elementary school these two subjects were not only separate but almost complete opposite.  Today however, my perception has changed and I see more similarities between the two than differences.

First of all, there IS reading in mathematics…reading of textbooks, word problems, literature, the whiteboard…the ability to read supports the student’s ability to take in information, comprehend problems and creating meaning.

Secondly, reading at it’s very essence is thinking.  It is the interpretation of a set of symbols (letters and words), and using our understanding of the symbols to create meaning.  This process must involve thinking.  Likewise, mathematics is the interpretation of a set of symbols (numbers, objects, representations, letters, and words) to create meaning, and gain understanding.   This process must also involve thinking.   Since both subjects are looking to strengthen thinking it only makes sense that we use the strategies and supports for strengthen student thinking, and comprehension in reading to strengthen thinking and understanding in math.  Creating consistency between the strategies can foster students ability to make connections and allows them to build on an existing foundation within a new context.

In reading we use the Super 7 Reading Strategies to support thinking and comprehension.  In mathematics these same strategies can be built upon to support mathematical thinking comprehension.

  • Using knowledge of narrative or expository text features/structures
  • Determining relevance
Determining Importance

  • Determining what is given in the problem
  • Determining what we are being asked to discover
  • Using existing knowledge in mathematics to solve new problems
  • Determining relevance

  • Reviewing, sorting and sifting through information leading to new insight as thinking evolves

  • Reviewing, sorting and sifting through mathematical problems and information which leads to new insights in math
Monitoring and Repairing Comprehension

  • Monitoring understanding and knowing how to adjust when meaning breaks down
Monitoring and Repairing Mathematical Thinking

  • Monitoring understanding and knowing when to stop and adjust (when thinking breaks down)
  • Identifying where thinking broke down and trying another solution

  • Clarifying meaning by asking questions before, during and after reading to deepen comprehension

  • Clarifying mathematical thinking by asking questions before, during, and after solving problems to deepen understanding
  • Asking questions of others about their strategies for solving problems.


So next time you are explicitly teaching comprehension strategies to your students in reading consider the possibility of expanding on those strategies in mathematics.  As Maggie Siena  (2009) so eloquently puts it “we can become more effective teachers of mathematics by drawing from our successful experiences with teaching literacy.  It’s the art of lighting two candles with one flame” (p.2).

Exploration by it’s very nature is a step into the unknown.  Armed with no map, no set of steps, no set path, the explorer embraces the excitement of discovery with a willingness to get lost in the adventure.  Imagine for a moment exploration that was planned, with every destination known, every step predetermined…it would not be as much fun, it would not belong to the explorer, and it would not be exploration.

Mathematics is a place where exploration is not only possible…it is necessary.  Through exploration and play we can breath life into the learning of mathematics, as we open up opportunities for imagination, creativity  curiosity and wonderment.   These qualities can carry the mathematics beyond the textbook, the worksheet, the drill and practice.  They can make mathematics come alive.  This exploration needs to belong to the explorer and the explorer in every learner needs to be given opportunities to discover and create in mathematics.  There may be  times when we would want to give students the map with the route laid out and support them on reaching the destination but there should also be times where students face a problem or situation and need to reason your way to the other side, without the road map.   In those times it becomes about finding their own way, embracing the different but equally valid paths/solutions of others, and truly discovering not only the science of mathematics but it’s artistry and creativity as well.  This exploration does not need to happen in isolation.  Explorers can join resources and thinking power to help navigate the journey and share in the excitement of discovery.

In this video Dan Meyer‘s describes the problems facing mathematics education when we take all of the exploration out of the subject.

1. Lack of initiative- Translation– I don’t want to do it!

2. Lack of Perseverance- Translation– It’s too hard!  I give up!

3. Lack of Retention- Translation– I don’t know.  Blank look.

4. Aversion to word problems- Translation– Can I just have a sheet of numbers.

5. Eagerness for a formula- Translation– Can you just show me how to do it?

By purposely and deliberately creating an environment where mathematics exploration and discovery flourish we can harness the inner mathematics explorer in our students.


Exploration is really the essence of the human spirit.  Frank Borman

My Melt Down

I remember the day my world fell apart in the face of new pedagogy in mathematics. I was working in a rural school division in Saskatchewan and was in the middle of a Cognitive Coaching workshop with 50 people that I did not know… and the facilitator asked for a volunteer to model a problem solving conversation.

  After teaching for 14 years I had reached a point where I felt I did not know anything about teaching and learning. I ended up being a crumbled mess on the floor of that workshop – embarrassed at my emotional outburst and doubting my ability to teach, or facilitate, or guide, or whatever it was I was supposed to be doing.

That was six years ago.

So, how did I get past the Earth shaking moment when I lost my ability to believe I could meet the many challenges that I was facing?


My Journey

  1. Professional Learning – I went to a math workshop where the facilitator gave me a ‘living example’ and helped me to understand what some of the language really meant, including Constructing knowledge, formative assessment, and inquiry. I finally understood that these aren’t things  I DO in my classroom, rather they are a way of being; a way for my students and I to interact in order for all of us to move forward – not just me moving forward with my well designed and superbly crafted lesson plans of the past.
  2. Professional Community of Learners – As Physics teachers, we formed a community of learners.  There were 14 of us that were awarded a McDowell Research Grant. We spent time planning, collaborating, critiquing, and reflecting together. These discussions gave me my ‘Living Examples’ and helped me to figure out how my students and I were to interact with the curriculum so that we could all explore the teaching and learning of science and mathematics… together.

So here I am six years later, and to be honest what I know now is not necessarily more than what I knew in the past – in fact, I know even more about how much I don’t know. But I no longer feel powerless. I know that there are people I can learn from and learn with. That has made all the difference.

An anchor on a boat can hold it in place, prevent it from going adrift, off course or lost.  In the same way anchor charts can hold thinking.  They can help learners get back on course by reminding them of discussions, activating prior knowledge, and point them in the right direction.   In mathematics anchor charts can be powerful instructional tools that support and enhance student learning.

Communication is an important process in our Saskatchewan Mathematics Curriculum.  To effectively communicate in mathematics students need to represent their mathematical thinking concretely, pictorially, symbolically  physically, verbally, in writing, and mentally.  With so many ways to communicate it is important that teachers support students in learning how to effectively communicate.  Anchor charts provide an opportunity for teachers to model thinking in writing, support and record the learning of the class, and build mathematical vocabulary.  By supporting communication in your  mathematics classroom you can help students to clarify, reinforce, and modify their understandings of mathematical  ideas.

To realize the potential that anchor charts can hold it is important to consider a few things when using them in mathematics:

  • Students will use them more if they have helped create them.  To prevent them from becoming wall paper co-construct them with your students.
  • Refer to them frequently during instruction and practice.  If a student asks a question which can be answered on the chart refer them to the chart.
  • Focus on one mathematical concept per chart.  Too much on a chart can limit its effectiveness and create visual overload.
  • Use mathematical vocabulary.  These charts will become a jumping off point for mathematical vocabulary building,  discussions and writing.
  • Don’t limit yourself to text.  Pictures, graphic organizers, models, even actual manipulatives can be taped to the chart to  support the concept.   Just remember to not overload the chart.  White space can make learning easier.
