About adding 10
The facts for adding 10 run from 10 + 0 = 10 to 10 + 12 = 22. The doubles fact is 10 + 10 = 20. Adding 10 to a number from 0 to 9 writes a 1 in front of it: 10 + 7 = 17. Every fact turns around: 10 + 7 and 7 + 10 are both 17. One fact family: 10 + 7 = 17, 7 + 10 = 17, 17 – 10 = 7 and 17 – 7 = 10.
