Intro to Adding/Subtracting Rational Numbers - 7.NS.1.c

Here is a lesson that will help you meet seventh grade math Common Core skills standards. Learners work in collaborative groups to solve a real-world scenario using the subtraction of rational numbers. They jigsaw into other groups and display their solutions on a number line. Although the lesson plan includes the use of the Geometer's Sketchpad® application, it can be taught sufficiently without it. Note that there is not a lot of teacher support in this write-up, and that you will need to create your own homework problems to assign as reinforcement.

Adding and Subtracting Mixed Numbers Lesson Plan

Students investigate fractions while adding and subtracting mixed numbers. They discuss how to add and subtract mixed numbers and they practice working with mixed numbers. They complete a worksheet while working with mixed numbers.

Lesson Design Protocol: Add and Subtract

Addition and subtraction are studied in this math lesson. Upper graders add and subtract whole numbers up to 1,000 with and without regrouping.

Subtracting Decimal Numbers

Students solve problems where they subtract decimals. For this math lesson, students read numbers with decimals and name the place value of a digit. Additionally, students read a word problem and place given numbers into a place value chart. Students subtract the numbers to get their answer.

Subtracting 3 - to 4- Digit Numbers From 4 - to 5- Digit Numbers with Regrouping in the Thousands

Fifth graders solve problems where they subtract and regroup. For this math/subtraction lesson, 5th graders solve a warm up problem following problem solving steps. Additionally, students match the number problem to the correct answer.   

Subtracting Mixed Numbers 2

In order to subtract mixed numbers, sometimes one may need to determine the least common multiple in order to find a common denominator. This is just what Sal does in this presentation. First, he shows how to find a common denominator and then the process needed to subtract two mixed numbers. Note: This video clearly explains the process of subtracting mixed numbers and would be appropriate for those just learning the concept.

Adding/Subtracting Negative Numbers

Guiding viewers through adding and subtracting numbers, this video includes many tips to help new learners internalize the concept of a number line. It clarifies the relationship between positive and negative numbers, including the relationships of their sums and differences.

Subtract Rational Numbers Using an Algorithm

Subtracting negative numbers can be confusing and hard to comprehend. Show your learners the steps to solving these problems and patterns to help them remember. The video uses a pattern to show how subtracting a negative computes the same as adding. There is a large focus that subtracting a number is adding the opposite. This is the last video in a four-part series. Use the prior videos for real-life examples with subtracting negative numbers. 

Adding and Subtracting Mixed Numbers

Fourth and fifth graders add and subtract mixed numbers and write fractions in their simplest form. They complete various online activities involving mixed numbers and fractions and observe a teacher demonstration on adding and subtracting mixed numbers. Links to Coolmath4kids.com games and associated worksheets are embedded in the lesson plan.
