We have been using pattern blocks to explore angles, parallel lines, to create symmetrical patterns and to solve some number problems. A pattern block set contains triangles, hexagons, squares, two different rhombi and trapeziums.
This week we created pattern block people and Mrs S challenged us to work out their age. The clue she gave us was:
We then made lots of pattern block people and had some fun searching the room for the oldest and youngest people created. Take a look at all our people and see if you agree with the ages that we have calculated.
We had one small problem. Mrs S forgot to tell us to put away the tan rhombi and the orange square. It is harder to calculate the age of our people if we use these shapes. One person used a square and some of us wanted to use the tan rhombus for hair or feet. At first we thought that one tan rhombus was equal to one green triangle. When we used an online pattern block site we found that this was not quite true. Instead of giving up trying to work out the age of the pattern block people that contain these shapes we learnt to use a new maths symbol. Mathematicians use this symbol show that something is not quite equal.
