Illustrative Mathematics: 4.oa Identifying Multiples

Administer an activity that fosters a child's understanding of multiples. Young mathematicians are guided to complete three tasks on a multiplication chart. Once they color the boxes with multiples of two, three, and four, learners...

The purpose of this task is for students to solve three comparisons problems that are related by their context but are structurally different. Multiplicative comparison is purposefully excluded from third grade (see 3.OA.3 and 3.MD.2),...
