What kids practice
Place value is knowing that in 34, the 3 means 3 tens (30) and the 4 means 4 ones. It's the idea that makes every bigger math topic work, from adding two-digit numbers to money. In first grade, kids count to 120 and learn to see a number as tens and ones.
Watch for
- Writing the number the way it sounds, so "forty-two" becomes 402.
- Mixing up teen numbers, like writing 71 for seventeen.
- Counting the rods as ones (counting 3 rods as 3 instead of 30).
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full tens and ones to 120 guide for 1st grade.
