Name: Period:
I. Identify the correct operation by placing the correct operator next to the expression. Use these operators:
+ − ÷ x

2 / Product
3 / Divide
4 / In excess
5 / Greater
6 / Percent
7 / Quotient
8 / Remainder
9 / Twice
10 / Minus
II. Place the word that identifies the operation. Use the following:
addition subtraction division multiplication
12 / 3a
13 / 16/b
14 / x2
III. Use these translations (and your notes) to help change the word problems that follow into numeric expressions. Do not solve.
5 less means −5
decreased by 3 means −3
twice a number means 2x
four more means +4
one-half means divide by 2
one-half means multiply by ½
Ex. / 5 more than x / X + 515 / 7 decreased by 5
16 / Twice a number n
17 / One-half of a number x
18 / The sum of 3 and a number x
19 / Nineteen less than a number n
20 / The difference between a number n and 6
21 / The product of a number x and 5
22 / Ten subtracted from a number y
23 / The quotient of a number x and 15
IV. Doubles! Try these by memory and then check your answer!
25 / (3)(3)= / (8)(8)=
26 / (4)(4)= / (9)(9)=
27 / (5)(5)= / (10)(10)=
28 / (6)(6)= / (11)(11)=
29 / (a)(a)= / (a)(a)(a)=
30 / (x)(x)= / (x)(x)(x)=
V. Exponents! Fill in the missing blanks.
31 / 12
32 / 23
33 / 32 / 9
34 / 44 / 4 • 4 • 4 • 4
35 / 52
36 / 63
37 / 72 / 7
VI. Substitution! Enjoy this activity and, please, show your work!
EX. / 12 / 6r / 72
38 / 1.5 / 2x + 3
39 / 0.5 / 15 ÷ x
40 / 1000 / x + 1
41 / 2/3 / 3x – 2
42 / 1 / 15
43 / 9.5 / 2x – 3x2 + 3
VII. Area of a square equals (side) times (side).
We abbreviate “side” by using the letter s
So, Area of a square can be said to equal (s)(s)
Or: Area of a square = s2
Use the formula to find the area of the following squares:
Challenge: What is the area of the shaded part?
Have a great weekend!
