Ideas for Early Math Estimation Activities


Early math estimation is fascinating.

Have you ever won a “Guess how many Xs are in the jar?”

Yeah, me neither. Still fun, though, right?

One of my favorite activities to present at a party with kids is a “Guess How Many?” jar. The winner gets all. The stakes are ridiculously high.

Estimate in Math 

I recently brought one of these jars to a Halloween party. The kids love “guessing”. I explained that they don’t have to “guess” randomly but that it is possible to “estimate” the answer.

These kids were fascinated with this concept. Then their teacher demonstrated her approach to estimating the amount in the jar. Don’t tell the kids, but she actually estimated EXACTLY the amount.

Did I let her walk away with the prized jar of candy corn?

What Does it Mean to Estimate in Math?

Estimation is a skill that occurs naturally but one that needs to be nurtured and massaged as the child’s brain develops. Think: use or lose it. Estimating a quantity weaves in mental computations that require problem-solving and critical thinking. 

Math estimation can be introduced to children concretely at a young age.  Children expand on the concept in elementary school between 3rd and 5th grade.
