This week we continued to explore the relationship between multiplication and area. The students worked in groups to find strategies for tiling rectangles on the floor marked off with painter's tape using copy paper and index cards. Then they used a single one-inch square colored tile to find the area of the same rectangle. The groups came up with some great strategies. Several groups figured out that they could easily determine the number of colored tiles that fit inside an index card (15 tiles). Then they multiplied that number by the number of index cards it took to fill the entire rectangle. Great mathematical problem solving! We also used Cheez-It crackers to tile squares and rectangles. The students shared strategies for finding the area without having to count every single square cracker. Some students used skip-counting while others used their knowledge of multiplication facts. Pictures from these activities are below.
