Happy Monday everyone!  I'm a day later than usual getting out the problem of the week but better late than never!  Students, don't forget to have your answer submitted to me by Sunday.

Grade 1-3:

Question: A small box contains 1 dozen cookies. A large box contains 2 dozen cookies. How many cookies are in 3 small boxes and 2 large boxes?

Grade 4-6:

Grade 7-9:

Question: Violins are measured in “fractional” sizes, which are not literal measurements of their proportions. The body of a full-size violin is 351/2 centimetres long. The body half-size violin is 32 centimetres long. By what fractional part would the body of the half size violin need to decrease in length in order to be literally half the length of a full size violin?
