...when you feel like you are talking to a wall.
Just when you've finished patting yourself on the back on how well Divagirl has been progressing, you take a day to review some concepts she'd mastered months ago. Sounds easy, right? Evidently not. She's had her numbers to one hundred since January. Every once in a while she'd forget some of the bigger middle numbers so we'd been working on numerical order NOT starting with 1. Things had been fine. Until today. I challenged her today by having her start at 33 and end at 51 and all went well until 39. So I reviewed tens place and ones place and asked her what comes after 3...(4) and what comes after 9...(10) and showed her the pattern of the other numbers such as 30 is 3 tens, 20 is 2 tens, 60 is 6 tens, you need 4 tens, what would that look like? Um, 5? (insert head slap) No. Repeat previous lesson, she says she gets the concept, there should be a 4 and a 0, do you know of a number that has a 4 and a 0? Yes, 90! (hitting head on table) No. I finally guided the process more by putting the number in front of her and asked her to find the number 40. Yes, I totally cheated and she totally needs more work in this area, but not today.
