This worksheet practices the skill of comparative relational thinking by asking students to determine whether 10 multiplication equations are true or false without calculating. For example, you know that 3 x 4 = 6 x 2 because 6 is twice as big as 3 but 2 is half as big as 4. Doubling the first factor and halving the second factor in the multiplication expression results in a multiplication expression of the same value. Students are asked to prove their answer by providing this information. Answer key included. Created by Amber Mealey.
This worksheet can be used to assess Fourth Grade Mathematics Florida Standard MAFS.4.OA.1.a: Determine whether an equation is true or false by using comparative relational thinking. For example, without adding 60 and 24, determine whether the equation 60 + 24 = 57 + 27 is true or false.
