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

I Have A… Who Has A…?

Students develop an ability to quickly identify and communicate the names of many different geometric shapes

How Many Dots Do You See?

Students use visual pattern/arrangement to develop how to recognize quantity with accuracy and speed

How Many? 5-Frame and 10-Frame Inside-Out

Students develop their spatial structuring of numbers and strengthen their working memory to compose and decompose

Secret Shape Code

Students develop spatial skills by practicing how to describe the location and orientation of different cut-out shapes

Box or Not?

Students strengthen visualization and mental rotation skills to develop the ability to transform a 2D shape into 3D

Build a Structure with 3 Different Views

Students examine 3 views of a structure (top, front and side views) and use interlocking cubes to recreate the shape

Draw 3 Views from a Structure

Students develop the ability to picture structures from different perspectives and reconstruct the figure from memory

Square Moves

Students take a hands-on approach to learning transformation by using square tiles to recreate transformed shapes

See It, Build It, Check It (3-D Version)

Students exercise their ability to recreate 3D geometric shapes from memory using pattern blocks

Can You Make A Square?

Students utilize their spatial reasoning skills to create squares using different tangram combinations

Hexagon Card Game

Students race to completely fill in the outline of a hexagon using different combinations of pattern blocks

Missing Puzzle Pieces

Students develop reasoning and discussion skills by identifying the missing piece of a puzzle from options below

See It, Build It, Check It (2-D Version)

Students exercise their ability to recreate 2D geometric shapes from memory using pattern blocks

Shape Transformer

Students work together to understand transformations as a series of inputs and outputs using the "Shape Transformer"

Hole-Punch Symmetry

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

$Spatializing Area$

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.

The Animal Grid Game

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

Square Tile Grid Symmetry Quick Image

Students have to visualize a series of reflection challenges made of square tiles and recreate them from memory.

Pattern Block Symmetry Quick Image

Students have to visualize a series of reflection challenges made of pattern blocks and recreate them from memory.

Pattern Blocks Quick Image

Students have to visualize a series of challenges made of pattern blocks and recreate them from memory.

Multilink Cube 3D Quick Image

Students have to visualize 2D images of 3D shapes comprised of multilink cubes and recreate them from memory.

Base Ten Block Quick Image

Students have to recreate from memory an image composed of base ten blocks. Then they calculate the sum.

Target Number Game

Students select target numbers and attempt to scoop up that many countable objects.

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.

Designs and Patterns on Grid

Students learn how to read letter-number coordinates by creating designs and patterns on grid.

Pentomino Battleship

Students practice reading letter-number coordinates by playing a battleship game with a partner.

Perspective Taking

Students learn perspective taking by identifying the top, side, and front view of 3-D figures.

Daily Calendar

This daily lesson with many small activities gives students the opportunity to practice all five strands of math every day.

Doubles

Students organize doubles from 0 to 12 in a way that makes sense to them. This allows them to see number patterns.

Barrier Game

One student builds a structure and gives instructions to his/her partner to build an identical structure.

Building with the Mind’s Eye

Students visualize and build a figure in their mind's eye. Then they describe it for the class.

Number Hunt

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

Collect the Shapes

Children collect 2D shapes on a grid by giving directional instructions and answering questions on shapes attributes.

Multiple Turnover Game

In this game students try to identify whether their cards contain multiples of a given factor.

Curious George and the Rabbits

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

Adding Up the Number Line

In this addition and subtraction game players attempt to arrive exactly at 500 on the number line.

The Cube Challenge

In this lesson, students work together to build 21 unique structures out of 3, 4, and 5 unifix cubes. Can you build them all?

Upside Down World

Students work with unifix cubes to rebuild "buildings" that have been turned upside down!

Find Your Match

Students collect a matching number pair or two cards that add or subtract to a predetermined sum/difference.

$Scrambled Egg Math$

Scrambled Egg Math

Children shake the egg carton then roll a die to determine whether they will be adding or subtracting.

Super Mind

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