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!
