Algebraic Thinking Review

What word problem does the strip diagram represent?

• Mrs. Moore bought 2 medium sized bags with M&M's that contained 80 M&M's each and 1 large bag that contains 250 M&M's.  How many total M&M's does she have?

• Mrs.  Moore has 250 M&M's.  She has 80 red M&M's and 80 blue M&M's.  How many green M&M's does she have?

• Mrs. Moore bought 3 bags of M&M's.  Each bag had 80 M&M's inside.  How many bags would she needs to buy in order to have 250 M&M's?

• Mrs. Moore had 250 M&M's.  She gave her class 80 M&M's and her switch class $80 M&M's.  How many M&M's does she have left?

A factory makes 400 refrigerators every day. The factory makes 125 more stoves per day than refrigerators. Which equation can be used to find x, the total number of refrigerators and stoves the factory makes in one day?

• x = 400 + (400 + 125)

• x = 400 + 125

• x = 400 + (400 - 125)

• x = 400 - 125

What number goes in the empty box?

• 9

• 19

• 20

• 10

Which equation best matches the strip diagram?

• 40 - 25 + 20 = Q

• 40 + 25 + 20 = Q

• Q - 40 - 25 - 20

Based on the table, if the output is 21, what is the input?

• 4

• 3

• 7

• 21

What is the rule?

• Input x 2 = output

• Input x 3 = output

• Output x 3 = input

• Input + 3 = output

Which equation would you use to find the area of this shape?

• 16 x 10 = a

• 16 + 10 = a

• 16 + 16 + 10 + 10 = a

• 32 + 20 = a

Which equation matches this strip diagram?

• 86 + 26 = P

• 26 - 86 = P

• 86 - 26 = P

Which equation represents the strip diagram?

• (984 - 344) ÷ 4 = X

• (984 + 344) x 4 = X

• 984 - 344 = X

• 984 + 344 = X
