Hi! So we have been working through level A for the past couple years and we are going to be starting level b next school year. I have loved level a, and I have found my daughter is learning a lot with it. As I have been looking through level b to plan for next school year, I don’t know if it’s just me, but it looks like it really jumps up in difficulty! I guess I had expected more addition and subtraction practice, but it really just seems like a huge jump from level a to level b. Has anyone else used it, and did you find that your children did just fine with level b as well? Thank you!
