This week the 3rd graders began the most important math unit of the year -- The Relationship Between Multiplication and Division! By the end of the year, your child should be fluent with his/her multiplication facts. But before we begin fluency practice, we must lay the conceptual foundation. Hands on practice is key!
Today, we read The Doorbell Rang, a picture book that uses a real-life division example that all kids can relate to -- sharing cookies! Throughout the year, when students need a reminder of how to solve a division problem, I will remind them that "division is like sharing cookies."
In this story, Ma makes a batch of 12 cookies for her two children to share. But as the doorbell rings, more friends come, and they have to share. As we read the book, the students modeled the sharing situations with their own paper cookies. As the story went on, they were able to predict how much each child would get once they noticed the patterns. "Ohhhh, each person gets 6 because I know two sixes are 12 and there are 2 children!"
After modeling each division situation in the story, the students got the chance to practice on their own. Partners used their paper cookies to practice solving division word problems and writing the corresponding number models. Enjoy the pictures and video below!
