Reverse! Reverse! My kids have gone crazy over this. I realized they needed to practice using the "Commutative Property," which states that you can "move around" numbers in addition and in multiplication. (Ie: "a + b = b + a" or "a x b = b x a") For this math warm-up, I say a multiplication problem, such as 6 x something = 30 (I usually mix up how I say the problem, whether I give factors or a factor and product.) Then, students put out their hands to indicate that they're ready to answer the problem. I toss them the ball, and they say the whole problem, such as 6 x 5 = 30. Then, the whole class says, "Reverse! Reverse!" The student responds with, 5 x 6 = 30. I've also used this when students are using their whiteboards. With the whiteboards, I can see an answer from all students, and then I can also ask them to label their factors and the product. I sometimes also ask them to give me a division question that corresponds to the given multiplication equation. |
