two games - both with a definite winning strategy, based on types of symmetry

**'cover it'**involves covering two adjacent squares

you could use dominoes

red Cuisenaire rods

sticks (or cut up bits of paper)

green goes first - and wins

green goes first - and loses

**'pick it'**involves placing counters in a ring (around any regular polygon) and at each turn a player chooses to pick either one or two adjacent counters

if they choose two counters then they must have been joined by a line in the initial configuration (i.e. be neighbours)
