Description

Division permeates mathematics at all levels. Students need to recognize situations that require division and be able to represent the problem symbolically. As skill development increases, students apply their knowledge to problem solving. Relating the concept of division to everyday experiences through the use of a cookie theme helps students make connections to the real world. Activities include sharing cookies, purchasing cookies, modifying a cookie recipe, and analyzing cookie package parameters.
