March Challenge - Years 1 & 2

Kimie and Sebastian were making sticks from interlocking cubes. Kimie made blue sticks two cubes long. Sebastian made red sticks three cubes long. They both made a lot of sticks.

Kimie put her blue sticks end to end in a long line. Sebastian put his red sticks end to end in a line underneath Kimie's.

a) Can they make their lines the same length?  How long would their lines be?
b) How many sticks (of 2 blue cubes) could Kimie use? 
c) How many sticks (of 3 red cubes) would Sebastian put down? 


Extension:  Can they make another line of equal length?

Solutions are to be completed by Wednesday 30th March.  Please post them into the Maths Challenge Box in the picture book library.
