DS, 10, has been learning multiplying mixed numbers. Today he was asking about using a calculator, but I didn't think it was a good idea until he was older. He knows how to multiply and divide bigger numbers, but to me the more he practices the better he'll be. But I was tempted to let him with problems like those. What do you think?

My daughter started using a calculator when she was 11 and only after she had shown a mastery of the problems with out it. Even now, at 12, I make her show me random problems with out the calculator to make sure she still knows how to do them.

I don't think I used a calculator regularly until high school math, so I don't think I will let my kids for a while still.

Quoting TJandKarasMom: My 10 yo has a lot of basic math to master before I let her rely on a calculator. My 11 yo still does most math without a calculator even though he is doing Prealgebra at this point. Honestly, he does most of it in his head so I know he doesn't need a calculator. He always wants to use one to convert fractions to decimals, but I don't let him because he only wants to do it because he doesn't like fractions. I want him to get comfortable with fractions so I make him use them if the problem uses them.

I don't rememeber using one until about 7th grade.

**I just recently let ds start using a calculator. He is 13 and is doing Algebra 1. I find it so important for kids to master the 4 basic operations - I mean really really master. It makes any higher math so much easier.**

Yeah, I was thinking about having him do like the first half of the page with out one, then he can dothe rest with one.

My guess is ill do the same with DS when he's older - basically pick & choose what to use it for

I just started letting DS 10 use a calculator for his math within the last couple of weeks or so ....BUT he's finishing up Algebra 1 and I thought it was time from him to focus more on the steps and not the math. He's been doing big multiplication and division problems for at least 3 or 4 years now and I know he's proficient.
