Classmates from Moorfield Junior School, **Thomas**
and **Robert** , explain their strategy for solving
some of the challenges of *Shapes on the Playground* :

To find the shapes that Sally drew they explain:

"We listed all the numbers that add up to 100 and then starting
multiplying them by 4 and 8.

The answer we got gave us the solution, 7 squares and 9
octagons.

We then worked Ben's out the same way.

The answer we got gave us the solution 20 squares, 0 triangles and
0 hexagons!!!"

Why do you think **Thomas** and
**Robert** multiplied by 4 and 8? Do you agree with
their answer for the shapes that Ben drew? The problem told us
that, "Ben drew triangles, hexagons and squares".

The pupils from **St. Aldhelm's C.E. Combined
School** agree with the solution for Sally, but for Ben they
have some other thoughts. They made tables showing the amount of
chalk used for each shape and then by completing the tables they
discovered how many of each shape Ben would have drawn if he drew
20 shapes in total.

The answer they arrived at was that Ben drew 10 triangles (30
metres), 5 squares (20 metres) and 5 hexagons (30 metres). This
used 8 sticks of chalk, as each stick drew 10 metres, leaving two
unused sticks. Well done St. Aldhelm's! Can you recognise your
initials? **LM, ED, RD, HS, KT, DF, LH, NT, AND

Mel and Katie from Loretto Junior School also worked out that Ben could have drawn these shapes:

- 17 squares, 2 triangles, and 1 hexagon
- 8 squares, 8 triangles and 4 hexagons

Very well done!
