What I Teach in November

Tap a month to see its units and lessons.

Numbers to 10 and 2D Shapes

September starts with numbers to 10 and 2D shapes. Short lessons and hands-on centres help you build routines while students get to know the materials.

Sorting and Patterning

October moves into sorting and patterning. Both are hands-on, which makes them a good fit for math centres.

Blog posts: Sorting · Patterning

Measurement and Symmetry

November brings non-standard measurement and symmetry, two units full of building, comparing and creating.

3D Figures, Tally Marks and Graphing

December moves through 3D figures, tally marks and graphing. Tally marks lead naturally into collecting and showing data.

Ordinal Numbers, Equal Sharing and Spatial Relationships

January covers ordinal numbers, equal sharing and spatial relationships, with plenty of real-life language and hands-on practice.

Decomposing and Composing Numbers

February begins Term 2 with decomposing and composing numbers, the foundation for addition and subtraction.

Subitizing and Number Paths and Lines

March builds quick number recognition with subitizing, then moves on to number paths and lines.

Addition and Subtraction

April brings early addition and subtraction, building on the composing and decomposing work from February.

Teen Numbers and Canadian Coins

May covers teen numbers and Canadian coins, two topics that connect easily to real-life play.

Estimating and Probability

June wraps up the year with estimating and probability.
