Students will work to solve an open-ended multiplicative comparison task. They can use manipulatives as a hands-on introduction to the topic. They will need to write equations and solve a word problem involving multiplicative comparison.
Students will take a deeper dive into word problems to gain a firm understanding of multiplicative comparison. They will compare problems using additive vs. multiplicative comparisons and problems where either the set or the product is unknown. The activity also includes a matching game for students to match equations, models, and comparison statements.
In this resource from Bridges in Mathematics, students use a picture of a giant's doorway to solve multiplicative comparison problems. They have to write an equation and find the answer using appropriate units. A challenge problem includes a fractional scale factor.
