Here's a warm-up activity to get out the giggles before you get the party started. Kids will pick up math skills while they're moving.
At the Party
Once kids have arrived at the party, have them stand in a line or circle. Demonstrate a simple pattern for the kids, like "Clap, Clap, Stomp, Clap." You can ask for volunteers to help you demonstrate the pattern: the first kid claps once, second kid claps once, third kid stomps, and fourth kid claps once. Once kids have the hang of it, start the pattern game. Have each child participate in the pattern once and then make it more challenging by having kids repeat the pattern faster. Once someone makes a mistake, like clapping instead of stomping, everyone laughs, CRAZY SHAKES, and tries again! See how fast the gang can go while making a perfect pattern. Then try a different pattern.
