I have used both TT and MUS with my dd- also a handful. She has SPD with behavioral problems and was adopted out of an abusive situation and many foster care homes. She has trouble with the sequential thinking and repetive actions (she won’t follow rules of math, but will do a problem or two, then decide to do something compeletly different-just pluggin in numbers; very exasperating!)
We used TT3 with my then10 yr. old because she had gotten stuck at place value and couldn’t move beyond adding and subtr. single digits! I had started her on Dev. Math, then Math MAmmoth then, thinking that TT would be good for her, I tried that-not good. What happened was she was doing the problems on the computer and in her book, but she wasn’t understading what she was doing at all. Sshe was getting the ones in the book wrong and on the computer correct. I think one part of it was that she wanted to get to the games, so she’d do the problems on the comp. correctly, but wouldn’t try hard enough or concentrate in the book. In addition, since it was spiral, she wasn’t getting the repetition she needed to seal the concepts. It went too fast without enough practice.
Finally, after no improvement I switched to MUS Beta. Since she is kinesthetic (of course, with the SPD), she finally grasped the place value concept and she could move on. We;ve only gotten stuck a couple more times, but I’d have her rewatch the DVD, narrate to me what to do and then do it repeatedly (printing out more worksheets) until I thought she was ready for the test. Sometimes, I’ve had to explain how to do it a slightly different way.
So we’re sticking with MUS. MY suggestion is to stay wiht what you’re doing, but stop doing it for so long. At her age, 15 min. on math is enough-if she’s not getting it, going past that isn’t going to help any. I’ve worked with my dd two times in one day in two 15 min, increments to get what was needed done and still maintain her attention. So you can do some math for 15 min., then stop and switch to something using the other part of her brain and at another time of the day, come back and try again. She’s only 7 and not behind. It’s better to have deeply concentrated 15 min., 2x a day than one poorly concentrated time of 1 1/2hr. with you and her getting frustrated.
If it’s an obstinence problem, the breaking it up into 15 min. increments keeps you in charge and not her. Since the time she’s requiring from you, she’s in control, not you. She may remember more than she thinks, she just may need more practice, too. I find that MUS has a good amt. of review from previous concepts. You can print extra problems from the website and she can rewatch the DVD and narrate to you until she gets it.
What do you think it is that’s got her stumped? Lack of comprehension, obstinence or a little of both? Can she tell you what she doesn’t understand? Not remembering is sort of vague; though with breaking down to only 10-15 min. a lesson, you may see a change in that.
Is she auditory? Would addition/subration facts to music help her? It did mine.
