What’s on the Tens and Ones poster
The rule, 4 worked examples, and the mistake everyone makes.
- In a two-digit number, the left digit counts tens and the right digit counts ones.
- 47 = 4 tens + 7 ones
- 36 = 3 tens, 6 ones
- 80 = 8 tens, 0 ones
- 19 = 1 ten, 9 ones
- 52 = 5 tens, 2 ones
- Common mistake: 47 is a 4 and a 7 → 47 is 40 and 7
Ten ones can always be traded for one ten. That trade is what carrying is.
