Making the Foldable

• Fold the paper in half (hot dog)• Fold in half again• Fold in half one more time• Unfold it. It will look like this:• Now fold it back like a hot dog• Cut along the folds HALFWAY

• Label the boxes like this:• Now open each flap. On the bottom of the flap (uncut side)

write the word that goes with each letter on the front. – Under the P, you should write Parenthese– Under the E, you should write Exponents– Under the MD, you should write Multiplication and Division– Under the AS, you should write Addition and Subtraction

• On the top of the flap, write the examples I have for you.– On the first flap, write (5 + 9) · 3– On the second flap, write(3 + 10) – 23 + 1– On the third flap, write 24 ÷ 3 · 2– On the fourth flap, write 4 + 2 – 1 AND 9 – 3 + 2

1. 21 + 5(7 + 3) - 20

2. 48 ÷ 4 · 2 + -6

3. 12 · 6 ÷ 3 · 2 ÷ 48

4. (8 + -10)3 + 6

7. (15 – 3 + 8 ÷ 2) ÷ 8 · 5

8. 30 – 3(7 – 2)

8 4 2 = 0

8 ÷ 4 – 2 = 0

8 4 2 = 16

Would + x work?

8 + 4 x 2 = 16

x + + = 28

Using the numbers 1 3 6 9

6 x 3 + 9 + 1 = 28

( x ) - ( - ) = 10

Using the numbers 1 3 6 9

(3 x 6) – (9 – 1) = 10
