Treat math as part of their daily lives _ Math has practical uses and kids must understand this early on. If they get an allowance they will need to count their money and if they spend any they'll need to get the right change and understand how much is left over. They are growing and they will love this fact. Let them fill out their own height chart. When they are helping you in the kitchen, let them help you measure the flour to bake cookies. They can also figure out how many slices of pizza each person can get or how many batteries must be used out of the pack. to power their toys. These are just a few simple ideas.
You may want to let them try and work out how long it will take you to travel somewhere when you get in the car, by telling them what speed you'll be traveling and how far away your destination is.
