SEE: We saw that we had to place the numbers 1-5 (there were 4 of each) in a hexagonal

shape made up of triangles. We had to use all of the numbers even though there were too many triangles. Also, we saw that we had to make all of the rows both horizontally and diagonally equal up to the same total.

PLAN: We planned to get some counters and draw numbers on them so that we could move them around much easier.

DO: We drew some numbers on counters so that we would be able to place them on our enlarged hexagon. We noticed that our solutions for question 2 were the positions for the four numbers of one of the digits.

These are two of the solutions that we got.

CHECK: We checked all of our rows in each direction to make sure that we had a 1, 2, 3, 4 and 5 in each. Our total for each row is 15

Note: We added colour to the team's diagram to emphasize the way in which a solution to the transversals question can be used to position the numbers. Once that link with 'a related problem' has been made, the rest is ... too easy!
