How to make a board game

See its quite simple., and im 15!!
take a board game for children ages 4-7
The are just starting to learn their ABC`S to Math equasions
first start off by making the boarding game with bright colors., to catch their attention.,
then start off by putting squares for a path., or circles., stars.,or even footprints., BE CREATIVE!:)
next start off by looking for ideas and questions etc. to put on the squares(or circles... which ever) like for example start off by one of the squares to ask the kids to say the alphabet backwards or something., and for the older children put in math equasions., with a deck of cards on the side one pile is additions., and the other can be subtractions., or some squares can sayy lose a turn or one will lead them to another square somewhere else in the game

i am doing this board game as a project for my french class., great gotta translate!.,
But when my new baby sister is born i will deffinetly be playing this game with her:)
