What kids do
“Read the number in each square. Color it the color in the key. What do you see?”
Teacher tip
Don’t tell kids what the picture is. The reveal keeps them checking the key on every square.
How to use it
- Pair the sheet with real counters: build the number, then write it.
- Use a fat crayon or a triangle pencil for kids who still grip with a fist.
- Do the first problem together under a document camera, then let kids finish on their own.
Watch for
Reversals of 2, 3, 5, 7 and 9 are normal at this age. Point to the start dot and model again rather than marking it wrong.
Talk about it
- Can you find this number somewhere in the classroom?
- Which problem was the hardest? What made it hard?
