Current State ofAlgebra Preparation

Major Emphasis

• Ratio and Proportional Relationships—

Includes analyzing proportional relationships, applications of unit rates and solving multistep ratio and percent problems

• The Number System—

Includes application and deepening of previous understandings of rational numbers, and solving real-world problems using the four operations.

• Expressions and Equations—

Includes application of properties, comparing arithmetic and algebraic solutions, using tools strategically, fluency in solving equations, and solving real-world and mathematical multistep problems in equations and inequalities.

• Geometry

Includes solving problems involving scale drawings, circles, triangles, angle measurement, and real-world problems involving 2 and 3 dimensional objects.

• Statistics and Probability

Includes finding probabilities of events and collecting and using data to draw inferences.

• Functions---understanding the meaning of a function, graphing a linear function, and solving pairs of linear equations.

• Geometry—Describe transformations.

• Having built a strong foundation K-5, students can do hands on learning in geometry, algebra and probability and statistics. Students who have completed 7th grade and mastered the content and skills through the 7th grade will be well-prepared for algebra in grade 8.

• The middle school standards are robust and provide a coherent and rich preparation for high school mathematics.

• The high school standards call on students to practice applying mathematical ways of thinking to real world issues and challenges; they prepare students to think and reason mathematically.

• The high school standards set a rigorous definition of college and career readiness, by helping students develop a depth of understanding and ability to apply mathematics to novel situations, as college students and employees regularly do.

Grade 7 Mathematics Common Core Sample Questions Domain: Ratios and Proportional Relationships

• Appliances at Discount City Store are on sale for 70% of the original price. Eli has a coupon for an 18% discount on the sale price. If the original price of a microwave oven is \$500, how much will Eli pay for the oven before tax?

• A \$440 B \$287 C \$260 D \$240

• Commentary: This question aligns to CCLS 7.RP.3 because it assesses a student’s ability to compute successive percents.

• Rationale: Option B is correct. This involves the application of 70% to the original price of \$500 followed by the application of the 18% coupon on the sale price.

• .70(500) = 350

• 350(.82) = 287 or

• 350(.18) = 63

• 350-63= 287 or

• 500 x 0.7 x 0.82 = 287

Domain: Expressions and Equations

• When John bought his new computer, he purchased an online computer help service. The help service has a yearly fee of \$25.50 and a \$10.50 charge for each help session a person uses. If John can only spend \$170 for the computer help this year, what is the maximum number of help sessions he can use this year?

• Key: The maximum number of help sessions he can use this year is 13.

• Commentary: This question is aligned to CCLS 7.EE.4b because it assesses a student’s ability to write and solve a linear inequality based on a word problem with a real-world application.

• Rationale: If x represents the number of online help service sessions per year, then

• 10.5x + 25.50 ≤ 170

• 10.5x ≤ 144.50

• x ≤ 13.76

• 13 sessions

• A scale drawing for a construction project uses a scale of 1 inch = 4 feet. The dimensions of the rectangular family room on the scale drawing are 7.5 inches by 12 inches.

• What will be the actual area of the floor of the family room after the construction project is completed?

• A 90 square feet B 156 square feet C 360 square feet D 1440 square feet

• Commentary: This question is aligned to CCLS 7.G.1 because it assesses a student’s ability to use scale drawings and compute the area of a figure.

• Rationale: Option D is correct. If the dimensions of the family room on the scale drawing are 7.5 inches by 12 inches, the dimensions of the actual room will be 30 feet by 48 feet. Therefore, the actual area of the family room will be 30 x 48 = 1440 square feet.
