Understanding Algebraic Expressions

Addresses the following 1st Grade standard from the Common Core State Standards for Mathematics:
Expressions and Equations 6.EE - Apply and extend previous understandings of arithmetic to algebraic expressions
2. Write, read, and evaluate expressions in which letters stand for numbers.
a. Write expressions that record operations with numbers and withletters standing for numbers.
For example, express the calculation “Subtract y from 5” as 5 – y.
b. Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient);

Write an expression for the following:

Subtract 4 from x.

Multiply y by 5.

the product of 2 and b

the sum of a and b

the quotient of w divided by 3

Add 8 to 5 times p.

Multiply 25 by c.

x with a coefficient of 10

Add 20 to the quotient of
i divided by 4

the sum of 3 terms,
x and y and z

the product of 2 terms,
100 and w

Add b to the product of
m and x

the sum of 2 times m
and 3 times n

Subtract 3 from the product of
2 factors: 8 and t
