As your child plays hopscotch they will be developing lots of physical skills.
Tossing the stone or beanbag develops eye-hand coordination.
Hopping is a complex skill and takes lots of practice. When your child is practicing they will be developing balance and coordination. They will also be making connections in their brain which will later help with creativity and reasoning.
As they stop and start in the game your child will be developing body rhythm and a sense of how their body moves.
Hopscotch also helps your child to recognise numbers and the way that they are ordered.
