Needing math curriculum advice
So my son just finished first grade Singapore Dimensions. He loved it in kindergarten and flew through it. In first grade he did pretty well until we got to subtracting double digits. We stayed on the same lesson for two weeks, but he unfortunately never grasped it 100%. Now I’m looking forward to second grade and I’m not sure what to do about math. We originally loved Singapore Dimensions but then it became a big struggle and I’m worried next year will be even harder for him. I was wondering if doing a year of Math-U-See would help him to get back on track and then we could switch back to Singapore in third grade. Or if Singapore just isn’t right for my son and I should just focus on finding a new curriculum to stick with. I’d appreciate any advice!
