SHOW ALL YOUR WORK
Level 1 Sets of Four: Make a list of things that come in a set or group of 4. (Example: a football game has 4 quarters). Can you make your list include 4 or more examples?
Level 2 The Fourth Little Pig: The 3 Little Pigs in the famous story had a lesser known sister. She was a master house builder so the wolf didn’t even try to blow down her house. See if you can help her make a list of building supplies she needs:
 Each wall of her square house is 12 feet long. If she needs to put one wall support every 2 feet, how many wall supports does she need to buy?
 The outside walls are built with bricks. Each brick is 6 inches high. If she wants to make the walls 8 feet high, how many layers of bricks does she need?
 To go around the house with one layer of bricks, she needs 48 bricks. Using your answer in #2 above, how many total bricks will you need.
Level 3 4 Fours Problem:
Can you figure out how to use fours to make equations that equal the number in the chart below? One example has been done for you.
Rules:
 You must use exactly 4 fours to make the solution.
 You can use any combination of addition, subtraction, multiplication, division, exponents, square roots, decimals, and parentheses. Remember to use the correct order of operations (see Ms. Simonson if you want help with the order of operations)
 You can combine the fours to make numbers like 44.
