Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 _ 4 = 24 is known, then 4 _ 6 = 24 is also known. (Commutative property of multiplication.) 3 _ 5 _ 2 can be found by 3 _ 5 = 15, then 15 _ 2 = 30, or by 5 _ 2 = 10, then 3 _ 10 = 30. (Associative property of multiplication.) Knowing that 8 _ 5 = 40 and 8 _ 2 = 16, one can find 8 _ 7 as 8 _ (5 + 2) = (8 _ 5) + (8 _ 2) = 40 + 16 = 56. (Distributive property.)
Students will use Ozobot Blockly to program their bot to randomly choose two or three numbers. Then, students will use the numbers as factors to practice multiplying using the commutative and associative properties.
Students will program their Ozobot to randomly select numbers to make multiplication problems, find the products, and apply the commutative property.
