This is a game to play with a grown-up!
Before playing this game, you might like to have a go at the simpler version, Board Block for Two.
You can play this game on the interactive pegboard, or on a real circular pegboard if you have one.
How do you play?
Firstly, choose the number of pegs on your board.
Decide what shapes you will be allowed to make.
You could allow:
- triangles and quadrilaterals
- triangles, quadrilaterals and pentagons
- triangles, quadrilaterals, pentagons and hexagons
- triangles, quadrilaterals, pentagons, hexagons and...
Take it in turns with the grown-up to add a band to the board to make any of the shapes you are allowing.
A band can share a peg with other bands, but the shapes must not overlap (except along the edges and pegs).
A player loses when they cannot make a shape on their turn.
Notes for grown-ups
This game helps reinforce the properties of different 2D shapes and encourages thinking about strategies.
play the game on a print-out of the geoboard (these can be found here
) so that the child can keep a record of the moves they've made.
encourage the child to change the number of pegs on the board or the amount of shapes which are allowed, and discuss how the winning strategy changes.
After playing the game, try to find a winning strategy and talk together about how this was found. How does this change if you play to lose?
