P4 tackle DFMs Maths Challenge Day 5

This time Primary 4 decided to take a split approach to this problem and used cubes and squared paper to work out the answer. We worked in pairs, (no Teddy today), and found the practical approach led to more correct answers. Some children took the challenge further and worked out an answer to b) too. We think we’ll let you work out the answer for yourselves!

Stepped Pyramid

This stepped pyramid has been built by young children and their teacher using some of the building blocks in the classroom. (The blocks are all cubes of the same size.)

(a) How many blocks would be needed to build it?
(b) Now imagine that the children want to build a similar structure with twice as many layers. How many blocks would be needed?
