Is it possible to calculate mathematics problems for primary education?

Answer 1

What do you mean by "calculate" in this context? If I have 5th graders working on least common multiples or 2nd graders working on subtraction, I just "make up" problems for them. If I need a lot of different worksheets on the same topic, I build an Excel spreadsheet that makes the kind of problems I need using the random number function, constrained to get numbers of the size and type my kids are working on. I used Excel for worksheets in Algebra topics in high school, too.
