Question

Do you think a bar model would be a good model for converting miles to feet

Answer 1

Yes, in my opinion I think a bar model would be a good model for converting miles to feet. It is simple and easy to understand

Answer 2

I think that a bar model would be a good model for converting miles to feet. In making a bar model, it would be easier to spot on the comparison of both equivalent values of miles and feet. But on the other hand, this also has limitations. This is only good for conversions with fixed, and whole numbers.
hope this helped
