Adding + 9

Amy succeeds well with doubling numbers e.g. 8+8= 16. Last week we started with the uneven numbers e.g. 7+ 7 = 14, 8+8=16. therefore 8+7 comes in between = 15. She practiced these combinations (1+2, 2+ 3, 3+4, 4+5, 5+6 etc.) in sequence until I was sure that she really grasped what it was about. We also did it with numbers written under each other, so that she began to grasp ones and tens and even carrying over. All the while we checked answers on the number line and she was thrilled every time the sum she worked out on paper, proved to be correct when we counted it on the number line.
Today we practiced 10 + (i.e. 10 + 2 = 12, 10 + 4 = 14 etc.). Thereafter we did 9+ sums. When you have to add 9, first add 10 and then the answer must be 1 less. What fun. Can't wait to see her homework tomorrow!
