1. 16 = _ ten and _ units 23 = _ tens and _ units 19 = _ ten and _ units 34 = _ tens and _ units 11 = _ ten and _ unit 25 = _ tens and _ units 42 = _ tens and _ units 55 = _ tens and _ units 78 = _ tens and _ units
Now try these:
3. 1 ten and 3 units = _ 2 tens and 8 units = _ 4 tens and 1 unit = _ 6 tens and 6 units = _ 7 tens and 3 units = _ 9 tens and 1 unit = _ 2 tens and 4 units = _ 5 tens and 9 units = _ 3 tens and 5 units = _
4. 8 tens and 3 units = _ 4 tens and 6 units = _ 1 ten and 8 units = _ 9 tens and 4 units = _ 7 tens and 1 unit = _ 4 tens and 9 units = _ 2 tens and 6 units = _ 3 tens and 4 units = _ 0 tens and 8 units = _
2. 99 = _ tens and _ units 83 = _ tens and _ units 65 = _ tens and _ units 79 = _ tens and _ units 12 = _ ten and _ units 47 = _ tens and _ units 20 = _ tens and _ units 51 = _ tens and _ unit 10 = _ ten and _ units
Recap I know more about tens and units. I can show tens and units on a place mat. I can show tens and units on an abacus.
