This big number grid is our hundred square. What do you notice? What do you wonder?
The hundred square is on the board. Numbers grow along each row in rows of ten. Watch where the small top-row numbers live and where the teens sit.
17 sits under 7 because it is ten more. We call 7 the little friend of 17. Every teen sits under its little friend.
Read the second row with me as ten and one, ten and two…
Today we explore: shade the number the teacher calls, up to 20. For every teen, say “ten and ___” before we check.
In your maths copy, write the second row of the hundred square: 11 to 20.
On your printed hundred square sheet, shade each of those numbers as you write it.
Shade the number for each clue. Before you shade, decide: top row or second row?
