Today we had a very tricky puzzle. We had to work out the number on Lilly's card. Lilly gave us some clues. She said her number was between 40 and 50. She also said that if she divided her number by 3, she would have one left over, and if she divided by 4, she would also have 1 left over. We used our counters to help us solve this.
Do you know what Lilly's number is?
