Grade 7 Common Core Math Curriculum

Grade 7 Common Core Math Curriculum

Listed below are Math quizzes for 7th grade students based on the Common Core Math State Standards.

For grade level assignments, we adhere to the Common Core State Standards Initiative's curriculum, in addition to considering other course curriculums such as GCSE(UK), Singapore Math, Australian and Indian Math curriculums. These courses will help students to perform well in local and major international competitions such as the Science Bee, Math Olympiad, American Mathematics Competition and so on. 

In grade 7, the focus is on four critical areas, namely

1) understanding and applying proportional relationships 

2) operations with rational numbers and working with expressions and linear equations

3) solving scale drawings, geometric constructions, and two and three-dimensional shapes to solve area and volume problems

4) drawing inferences about populations based on samples

Some of the mathematical practices that will be covered are:

  1. Make sense of problems and persevere in solving them.

  2. Reason abstractly and quantitatively.

  3. Construct viable arguments and critique the reasoning of others.

  4. Model with mathematics.

  5. Use appropriate tools strategically.

  6. Attend to precision.

  7. Look for and make use of structure.

  8. Look for and express regularity in repeated reasoning.

Grade 7: Ratios and Proportional Relationships

You will use your previous understanding of ratios that you learned in the 6th grade and now apply them to solving proportionality problems that involve either single or multi-step. 

You will be solving percent problems including those involving discounts, interest, taxes, tips, and percent increase or decrease.

You will be solving problems about scale drawings by relating corresponding lengths between the objects. You will be using the fact that relationships of lengths within an object are preserved in similar objects.

You will graph proportional relationships and understand the unit rate informally as a measure of the steepness of the related line, called the slope.

You will be able to distinguish proportional relationships from other relationships.

Grade 7: The Number System

You will develop a unified understanding of number, recognizing fractions, decimals (that have a finite or a repeating decimal representation), and percents as different representations of rational numbers.

You will extend addition, subtraction, multiplication, and division to all rational numbers, maintaining the properties of operations and the relationships between addition and subtraction, and multiplication and division.

By applying these properties, and by viewing negative numbers in terms of everyday contexts (e.g., amounts owed or temperatures below zero), you should be able to explain and interpret the rules for adding, subtracting, multiplying, and dividing with negative numbers.

You will use the arithmetic of rational numbers as you formulate expressions and equations in one variable and use these equations to solve problems.

You will build on your previous work with single data distributions to compare two data distributions and address questions about differences between populations.

You will begin informal work with random sampling to generate data sets and learn about the importance of representative samples for drawing inferences.

7.SP.A.1 Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.
