I am thinking of getting something else to help with math. My foster son is in grade 6 but is currently homeschooled. We are using Horizons 3 for the spiral nature. ( When we try to do mastery type math he forgets whatever we have learned when we go back to it. I have taught and retaught how to tell time.) We have supplemented with Math Mammoth Level 2 and level 3 where appropriate. He is all over the place with math. He can add 4 digit numbers together with multiple addenends, and we have been working on multiplication facts. We completed the section in MM Level 2 on subtraction. He did okay but needed a lot of handholding. But attempts to try MM Level 3 is just bringing frustration. He has build up some sort of block about subtraction and is currently just dissolving into tears whenever we tackle it. He has 2 problems with subtraction. He does not seem to have the facts memorized ( although he can figure them out). ( I don't know why that part is so hard when he can do addition okay?) If it regroups more than once, he forgets and just subtracts UP instead. If I correct him, he just dissolves into tears a lot of the time.
I feel like he HAS to get his subtraction facts down for his own peace of mind. He knows he doesn't know them and it stresses him out considerably. I was debating between Ronit Bird stuff or MUS Alpha. I feel like a lot of Alpha he might just breeze through but maybe not. I wondered if MUS Beta did much reviewing of Alpha and if that would be enough. The Ronit Bird site is down everytime I try to access it right now, so I am not sure what their work is like.
Note: I am currently waiting on the result of IQ testing with the Woodcock Johnson. I have no idea how helpful the report might be and if I need to wait on that to get a better sense of what to order?
