Mixing in Math activities are:

• Quick ways to mix math in to what after-school programs already do: sports, snack time, arts and crafts, playground games;
• Easy to prep;
• Easy to lead. You don't need math background or special training;
• Designed to be used with any school math curriculum and can complement homework in a variety of ways.
• Free!

Mixing in Math builds children's skills including:

• Time sense. Children use clocks and calendars to count down and keep track of time.
• Size sense. Children find and compare length, width, and height as part of games and art projects.
• Record-keeping. Children gather and organize fun facts about everyday things.
• Math talk. Children use words about size, shape, and numbers to add detail to stories and skits.
