RECAP: WHAT IS A PENTOMINO?
A Pentomino is a type of polyomino - a flat shape made from joining squares together.
How many squares do you think are joined to make a pentomino?

Pentominoes are made from 5 squares.
There are 12 different pentominoes:

TODAY, YOUR CHALLENGE IS TO FILL A RECTANGULAR GRID UP WITH TESSELLATING PENTOMINOES.
![Page 8: Thursday maths Tessallations and pentominoes 2 · 2020. 7. 11. · Tetrominoes(4squares) - there are 5, can you see them? Pentominoes A pentomino is made out of five squares that](https://reader036.fdocuments.net/reader036/viewer/2022070112/6054ee14f1071e21a6120bce/html5/thumbnails/8.jpg)
In this diagram the pentominoes have been labelled using letters.

EXAMPLES SHOWING DIFFERENT TESSELLATED PENTOMINOES FILLING RECTANGULAR GRIDS.
P,U and V can cover a rectangle that is 3x5 squares.
L, P, T and Y can cover a rectangle that is 5x4..
