Kids and calculators

What age do you usually let you kids start using a calculator for the bigger problems that have multiple steps?

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.

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

I encourage them to play with them at a young age. When it comes to school work I would probably let them when they hit pre-algebra. Honestly I rather them use their brains to figure out large problems in their head. I see more a point when they start doing problems are really difficult without using one. I also could see a point in using one to check their math.

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.

Hm, I let them get it out just for certain sections.

When I taught we used calculators for showing how to switch fractions to decimals (after we did it by hand) and for long division - not to get the answer but to help with multiplying large numbers like 38 in a problem like 123456789 / 38. Because really why do all that by hand?

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.
