Write About the Math
How many kits did the detective order? How did inverse operations help you solve this?¿Cuántos kits pidió la detective? ¿Cómo te ayudaron las operaciones inversas a resolver esto?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: In 3x = 21 the variable is multiplied, so I undo it with division. — Students read 3x as 3 groups of x, recognize multiplication, and contrast it with addition, knowing they will divide (not subtract) to solve.
