In seventh grade, students will focus on becoming fluent and accurate in adding, subtracting, multiplying and dividing positive and negative integers, fractions and decimals, solve two-step linear equations, solve single and multi-step word problems involving fractions, decimals and percent, be able to construct and interpret histograms, stem-and-leaf plots and circle graphs, represent proportional relationships using graphs, tables and equations, determine the slope of a line corresponding to a graph and determine the unit rate in a proportional relationship. Students will extend their understanding of probability and basic geometry into multiple events.
The Standards for Mathematical Practice K-12 describe behaviors that all students will develop in the Washington State Learning Standards. These practices rest on important “processes and proficiencies” including problem-solving, reasoning and proof, communication, representation and making connections. These practices will allow students to understand and apply mathematics with confidence.
Ratios and Proportional Relationships
- Analyze proportional relationships and use them to solve real-world and mathematical problems.
The Number System
- Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.
Expressions and Equations
- Use properties of operations to generate equivalent expressions.
- Solve real-life and mathematical problems using numerical and algebraic expressions and equations.
- Draw, construct and describe geometrical figures and describe the relationships between them.
- Solve real-life and mathematical problems involving angle measure, area, surface area, and volume.
Statistics and Probability
- Use random sampling to draw inferences about a population
- Draw informal comparative inferences about two populations
- Investigate chance processes and develop, use, and evaluate probability models
