Tennis Ball Maths!

Mrs Rush was given a whole lot of tennis balls by Koru Tennis Club.  She had a problem that she needed our help with.  She wanted to know how many tennis balls there were so she could work out how many to give to her teacher friends.

We started to count them in ones but there were so many, and we got interrupted and mixed up.  We problem solved and decided to put them into groups of ten. We all took turns at making groups of ten. Mrs Rush helped us to count in tens. There were 232 tennis balls!
