We have a broken house, so we don't feel burdened, and we like to review it in a school-based way. And the problem is not too difficult, so he's good.
I think it's good to have a problem with each member, and to be able to sort out and figure out what the missing part is.
Mastian R&D Center et al.: Unit-by-Unit Calculation Skills Math Step-by-Step Elementary Math Facto 2-2
The main factor in the material. The textbook is written by two authors to improve the computation of all classes. Two semesters of textbooks, each of six individual booklets, is three. It contains all the essential concepts that need to be understood, and it's a teaching that is optimal for both good, follow and present learning.
