Teaching Estimating Measurements

What it is

Estimating means giving a sensible answer before measuring: about how many paper clips long the book is, roughly how many cups the pitcher holds. The child then measures and compares the estimate with the result.

When a child is ready

Begin only after measuring with a unit is accurate, since an estimate is a judgment about a unit the child already knows.

If they struggle

Give the child something to measure against instead of guessing from nothing: a thumb width is about an inch, a large step about a yard. Write the estimate down before measuring and leave it there; erasing it afterwards to match the answer teaches nothing about how close the guess was.
