We have been working with Olivia on identifying and correctly pronouncing the double digit numbers up to a 100. So we came up with a game called, “Gushers for Numbers”. After dinner, I give her a gusher to place on the number I tell her. We also use it to work on her greater than and less than concepts. If she gets them all right, she gets to eat them. It works great and just after one week, she has dramatically improved recognizing her numbers.
