I CAN SOLVE WORD PROBLEMS WITH SQUARE AND CUBE ROOTS.

LET’S CONNECT THE DOTS

THINK – WRITE – PAIR – SHARE:

• We use squares and square roots to find…

• Real world example?

• We use cubes and cube roots to find…

HOW ARE SQUARES AND CUBES SIMILAR?

HOW ARE THEY DIFFERENT?

I CAN SOLVE WORD PROBLEMS WITH SQUARE AND CUBE ROOTS.

KEY WORDSSquare Cube

TODAY WE HAVE TO FILL OUT…

IDK!

WHAT DO WE DO?

1. Identify what is important in our problem (anything we underline).

2. Determine the question, equation needed to solve, and the answer. ANSWER YOUR QUESTION!

3. Reflect on the knowledge you had to have to complete your steps.

1. How did you know to multiply/add/take square root

2. How did you know which formula to use?

IMAGINE

Your parents just told you that you can completely redesign your family’s play room. You get to paint the walls, the ceiling, and even the hardwood floors. The first thing you have to do is decide what color to paint it. Then you have to figure out how much paint to buy. How will you know?

PAINTING THE FAMILY ROOM• The walls of your room are 11 ft. x 11ft.

• How much paint does it take to paint one wall?

• How much paint does it take to paint all walls, the ceiling and floor?

IDKI D K

REMEMBER:

• If it gives you the area and wants the side length, take the square root.

• If it gives you the volume and wants the side length, take the cube root.

WHAT IF?

Leanne has a swimming pool, but she needs to know how much water to put in it. Use the diagram below to decide what volume of water she has available in her pool.

9 ft. 4 ft.
