7th Grade Pre-AlGebra

September--November:  TOPICS 1-4: Key Concept Use rational numbers as a way to represent proportion and percent.

Connect rational numbers to the representation of equivalent ratios, especially unit rates, and use rational number operations to represent and answer questions about proportional relationships, including percent. Identify rational and irrational numbers using the connections between integer exponents and geometry.

December--January:  TOPICS 5-7:  Key Concept Understand the use of equivalent expressions to solve equations and inequalities.

Connect the properties of operations and equality to procedures for finding equivalent expressions and solutions to one- and two-step equations and inequalities.

February:  TOPICS 8-9:  Key Concept Understand the impact of sampling methods on making valid inferences, and use proportionality and percent to describe probability.

Connect data from a sample to procedures involving ratio, proportion, and percent used for drawing inferences about an entire population or for making comparisons between populations and evaluating the validity of the inferences made. Connect proportionality to the development of probability models and finding probabilities of simple and compound events.

March: TOPIC 10:  Key Concept Understand procedures for determining the measures of aspects of two- and three-dimensional figures.

Connect measurement procedures and formulas to two- and three-dimensional geometric characteristics including angle measure, area, surface area, and volume.

April--May: TOPICS 11-13: Key Concept Understand and measure geometry shapes in two- and three-dimensional including whether the shapes are congruent or similar.

Connect geometric measurement to transformations when shapes maintain congruence and solve real-world problems involving two- and three-dimensional figures.
