Early Years Math | The Robertson Program for Inquiry-based Teaching in Mathematics and Science

Hole-Punch Symmetry

Students visualize how paper that has been folded and hole-punched will look when the paper is unfolded.

Draw a Card and Build

Students take turns to drawing a number card and building a corresponding unifix tower to see whose tower is taller.

What Colour is Your Iris?

In this activity, early years students are introduced to graphing by observing the colour of their eye.

$Spatializing Area$

Spatializing Area

Students will approach measurement through visual comparisons, mental iterations, physical iterations, and tiling.

Roll & Build Bingo

Students take turns to tossing two dice and building a corresponding unifix tower to see who can complete a bingo first.

Unifix Counting Towers

In this activity, child works one-on-one with an educator to create a staircase of Unifix Towers representing 1 to 10.

The Animal Grid Game

Students love this offline coding lesson in which they get to be the zookeeper feeding animals.

Can You Draw This?

Students recreate an image of a square divided by a series of lines from memory and describe the strategies they used.

The Garden Patio

Children explore measurement and geometry and spatial sense through a narrative about a garden patio.

Using Names to Explore Graphing

Using children's names are great way to integrate literacy and math skills. This lesson explores graphing with names.

Story Problems

Story problems can be used throughout the year to reinforce number sense in a fun and engaging way!

Ladybug Houses

Students develop an understanding of numbers by comparing the number of ladybugs inside vs. outside of the house.

Cuisenaire Rods

Children investigate relationships between numbers by comparing the size of cuisenaire rods.

Origami Math

Students make connections between mathematics, history and visual arts, through origami.

Dominoes Parking Lot Game

Students are given the challenge of placing dominoes in their corresponding parking spot.

Number Hunt

Students practice one-to-one correspondence in this fun dice-rolling, bingo-dabbing game!

Curious George and the Rabbits

Students work together to demonstrate different ways to compose and decompose the number 10 or 20.

Introduction to Patterning

Students learn to recognize and extend patterns in different contexts and identify the features that define a pattern.

Patterns with Unifix Cubes

Unifix cubes are a great tool to use to explore patterns. In this lesson, children make their own patterns.

Patterns with Beads

Children are challenged with making multiple patterns with beads of different size, shapes, and colours.

Ladybug Patterns

By using only one kind of material, students are challenged to think about making patterns in a different way.

Pattern Hunt

Students go on a pattern hunt to look for naturally occurring patterns in their environment.

Name Pattern

Children continue to notice patterns in their name by using this grid and recognizing the repetition that occurs.

Growing Patterns

Through this fun story about magical snakes, children think about numerical patterns.

Super Mind

Children are presented with two-dimensional shapes and encouraged to explore the shapes.

Making Clocks

Children review different aspects of a clock. Then they have the opportunity to make their own!

Proportions

Students measure length and area through focused exploration in this guided activity.

Symmetry Game

This game allows children to be creative and practice the basics of symmetry through play with classmates.

Sorting Material

Students sort and describe different types of materials such as little animals, beads, and shapes.

Sorting Apples

Children try different types of apples while they pay attention to their senses, pick their favourite and make a graph.

Venn Diagram

Children learn how to use venn diagrams to sort different types of materials such as leaves and other manipulatives.

Introduction to Graphing

Graphs are a clear way to display data. Children use previous sorting lessons to learn how to make a graph.

Building a Graph Together

Students and their teacher review different components of a graph and build a graph together.

Graphs on Paper

Students practice precise graphing skills by using this graphing package to sort and classify objects.

Smarties Graph

Every box of Smarties contains a different amount of each colour. Children graph what their box contained.

Circle to Bar Graph

What is easier to read - a circle graph or a bar graph? Children discover the answer with this lesson.
