SIXTH GRADE

ALGEBRA
Students will investigate relationships between two quantities. They will write and solve proportions and simple one-step equations that result from problem situations.

M6A1. Students will understand the concept of ratio and use it to represent quantitative relationships.

M6A2. Students will consider relations between varying quantities.

a. Analyze and describe patterns arising from function rules, tables, and graphs.
b. Use manipulatives or draw pictures to solve problems involving proportional relationships.
c. Use proportions (a/b=c/d) to describe relationships and solve problems, including percent problems.
d. Describe proportional relationships mathematically using y = kx, where k is the constant of proportionality.
e. Graph proportional relationships in the form y = kx and describe characteristics of the graphs.
f. In a proportional relationship expressed as y = kx, solve for one quantity given values of the other two. Given quantities may be whole numbers,
decimals, or fractions. Solve problems using the relationship y = kx.
g. Use proportional reasoning (a/b=c/d and y = kx) to solve problems.

M6A3. Students will evaluate algebraic expressions, including those with
exponents, and solve simple one-step equations using each of the four basic operations.
