Quick counting review

One of my older son’s math club homework problems about counting gave him some trouble today, so for our Family Math project we decided to do a super quick counting review.

Problem 1: How many multiples of 9 are there between 500 and 800? My younger son took the lead on this one:

Problem 2: How many perfect squares are between 500 and 1700.

Problem 3: How many prime numbers are between 100 and 110?

These all seemed to go really well. Hopefully it was a worthwhile review – we haven’t talked about counting techniques in a while so it was probably time for a review anyway.
