Working with positive and negative numbers
Students start the year extending arithmetic to negative numbers. They add, subtract, multiply, and divide using number lines and real situations like temperature changes, debts, and elevation.
What does a student learn in
This is the year math runs on ratios and negative numbers. Students work with proportions to handle discounts, tips, scale drawings, and unit rates, and they add, subtract, multiply, and divide with positives and negatives. They also solve two-step equations and find the area or circumference of a circle. By spring, students can set up a proportion to solve a real-world problem and compute fluently with negative numbers.

Ratios, rates, and percents
Students use ratios and rates to solve everyday problems. Expect work on unit prices, tips, discounts, sales tax, and simple interest, plus scaling recipes and reading maps.
- 3
Expressions and equations
Students move from arithmetic to algebra. They write and simplify expressions with variables and solve two-step equations and simple inequalities that come from word problems.
- 4
Geometry and measurement
Students study shapes more carefully. They find area and circumference of circles, work with angles, and figure out surface area and volume of boxes and prisms.
- 5
Probability and statistics
Students end the year with chance and data. They predict how often events happen, compare samples from a larger group, and use graphs to compare two sets of data.

Standards for Mathematical Practice
-
Make Sense of Problems
Students read a problem carefully, figure out what it's actually asking, and keep trying even when the first approach doesn't work.
-
Reason Abstractly
Students take a real-world problem, strip it down to numbers and symbols to solve it, then translate the answer back into what it actually means in context.
-
Construct Arguments
Students back up their math answers with reasons and check whether a classmate's reasoning holds up. They learn that a solution isn't finished until they can explain why it works.
-
Model with Mathematics
Students take a real situation, like splitting a bill or planning a trip, and use math to figure it out. The focus is on setting up the problem, not just solving a worksheet.
-
Use Tools Strategically
Students choose the right tool for the math problem in front of them. That might mean reaching for a calculator, sketching on paper, or making a quick estimate to check if an answer makes sense.
-
Attend to Precision
Students say what they mean with exact words, use the right units (miles, not just "a lot"), and check their arithmetic so small errors don't change the answer.
-
Use Structure
Students learn to spot patterns and hidden structure in math problems, like noticing that two expressions are mirror images of each other or that a shape repeats at a different scale. That recognition becomes a shortcut for solving harder problems faster.
-
Express Regularity
Students notice when a math process keeps working the same way and use that pattern as a shortcut or rule. Instead of solving each problem from scratch, they spot what repeats and apply it.

K-8 Mathematics Content
K-8 Mathematics Content
-
Counting and Number
Grade 7 number work covers whole numbers, fractions, and negatives together. Students use what they know about how numbers are built to compare, place on a number line, and calculate across all three types.
-
Operations and Algebraic Thinking
Students solve word problems and write expressions using addition, subtraction, multiplication, and division. They translate a real situation into an equation, then work through it to find the answer.
-
Measurement and Data
Students read and build tables, graphs, and basic statistical summaries to make sense of real data. They use those displays to spot patterns, compare groups, and draw conclusions.
-
Geometry
Students sort and measure flat shapes (like triangles and rectangles) and solid shapes (like cubes and cylinders). They use what they know about angles, sides, and faces to describe what makes each shape different.
-
Ratios and Proportional Relationships
Students use ratio and proportion skills to solve everyday problems, like figuring out unit prices, scaling a recipe, or finding a percentage. This is the practical work of applying the ratio concepts learned throughout 7th grade.

Common Questions
What math should students be able to do by the end of the year?
Students should work confidently with positive and negative numbers, solve problems using ratios and percents, and write and solve simple equations like 3x + 5 = 20. They should also find areas and angles of shapes and read graphs and data summaries.
How can I help with math at home in just a few minutes a day?
Use everyday moments: figure out a tip at dinner, compare unit prices at the store, or work out a sale discount. Ask students to explain their thinking out loud. Five minutes of real reasoning beats a worksheet.
What does my child mean when they talk about negative numbers?
Students are learning to add, subtract, multiply, and divide with numbers below zero. Temperatures, elevations, and bank balances are good ways to practice. Asking what happens when it drops ten degrees from five degrees gives them a real picture.
How should I sequence the year?
Most teachers start with rational number operations, move into ratios and proportional reasoning, then into expressions and equations. Geometry and statistics fit well in the second half once students have stronger number sense. Probability often closes the year.
Which topics usually need the most reteaching?
Operations with negative numbers and proportional reasoning trip students up the most. Many students can find a percent but stumble when asked to reverse it or apply it to a markup. Plan extra practice and frequent review on both.
What should I do if my child gets stuck on a word problem?
Ask them to read it twice and tell the story back in their own words before touching numbers. Have them draw a picture or a simple bar model. Getting stuck is part of the work, so give them time before stepping in.
How do I know students are ready for the next grade?
Students should solve multi-step problems with rational numbers without a calculator crutch, set up and solve equations from a word problem, and explain why a proportional relationship is or is not proportional. Fluency with percents in real contexts is a strong signal.
Does my child still need to practice basic facts at this level?
Yes. Shaky multiplication and division facts slow students down on every new topic this year, from fractions to equations. A few minutes of fact practice a couple times a week pays off.
How much should students be writing about their math?
Plan for short written explanations on most assignments, not just answers. Asking students to justify a step or critique a sample solution builds the reasoning the year depends on. Sentence starters help reluctant writers get going.
