Today we are continuing looking at teen numbers. Take a look at the numbers below. The teen numbers are highlighted in blue.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
Teen numbers are all made from 10 and a bit more. For example:
11 is 10 and 1 more
12 is 10 and 2 more
13 is 10 and 3 more
These can be written as number sentences:
10 + 1 = 11
10 + 2 = 12
10 + 3 = 13
Choose a teen number and try to write the correct number sentence to match it. Start each of your number sentences with 10 + ? = ?
