About this worksheet
A chart where some rows give the number and some give the tens and ones. Fill in the missing part.
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 an answer key. See the full tens and ones to 120 guide for 1st grade.
