How to teach this

Have your child count the rods by tens aloud, then count on the ones: "10, 20, 30, 40... 41, 42, 43." Ask "how many tens?" before they write, so the digit connects to the blocks. Problems with zero ones, like 60, deserve a pause. That empty ones place is where the idea really sticks.

Watch for: Kids count every block as one, calling a ten-rod 'one.' Count the rods by tens out loud: 10, 20, 30. Kids reverse the digits and write 34 for 4 tens and 3 ones. The tens digit always comes first in a two-digit number.

Common questions about tens & ones

What are the rods and small squares in the pictures?: Base-ten blocks: a rod stands for one ten and a small square for one. Counting them links a written number to the amount it means.
How big do the numbers get?: Everything stays within two digits, up to 99, matching the first grade standard. Each print draws a fresh set of numbers.
