Prime time!

We used the Interactive White Board to cover multiples of 2, 5, 3 and 7 with counters.

What we found out...

  • Some numbers needed more than one counter
  • Some numbers didn't have any counters

Numbers with no counters are called PRIME numbers because they do not have any factors other than themselves and the number one!


  1. My best part was filling in the number square.

  2. It was fun! My best part was wen we we were filling the number square.
