These DIY puzzles come in three options: 
Matching sticks
Matching squares
Matching hexagons
They are a wonderful tool for teaching colours, shapes and even quantity as the square puzzle comes in a set of 4 and the hexagon puzzle in a set of 6. The puzzles become progressively more difficult with the sticks being intended as the starter puzzle to learn to match colours for 2 - 3 year olds. The triangles and squares involve matching two colours at a time and the hexagon can even challenge children up to around 10 years old as it requires alot of strategic thinking to complete it quickly in matching three colours in a hexagon shape. 
Each set comes with the base shapes and a set of stickers in a ziplock bag for your to make.
