Mix and Match Will’s family is going on a ski trip. It’s time to pack . “ I need sweaters, a scarf, and a warm hat,” says Will. “ I also need ski socks and my ski suit , but they’re downstairs.” Sara, Will’s little sister, wants to help. “Sara, we’re not going to the beach!” says Will. “Take out my swimsuit and T - shirt. It’s cold on the mountain, not hot!” “ But I want to help!” says Sara. “ I can match the socks.” Sara matches seven pairs of socks. “ Great job, Sara,” says Will.“ You’re a good helper.”
