Practice adding and subtracting positive and negative numbers to intercept the descending piñatas and then whack them for candy. Come on, keep the party going!

This interactive game has 4 categories: adding integers, subtracting integers, multiplying integers, and dividing integers. Students can play individually or in teams.

• starting temperature + change in temperature = final temperature
• final temperature – change in temperature = starting temperature
• final temperature – starting temperature = change in temperature

Students are asked to add integers using a number line.

Students are asked to combine rational numbers, including fractions and decimals, and use the properties of operations to simplify calculations.

Students are asked to find the difference between two integers using a number line.

Students are asked to rewrite a subtraction problem as an equivalent addition problem and explain the equivalence using a number line.

Students are asked to describe an example of additive inverse and demonstrate the concept on a number line.

Based on a student-focused scenario encouraging healthier lifestyles, students will perform a close and careful reading of an article encouraging active and healthy lifestyles. During the lesson, students will analyze data from Consumer Reports comparing and contrasting treadmills and elliptical exercisers. Using information gathered, students will compile data and persuade administrators to buy equipment that will align with the provided budget and fit in the given space.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

• starting temperature + change in temperature = final temperature
• final temperature – change in temperature = starting temperature
• final temperature – starting temperature = change in temperature

In this lesson, students will develop an understanding that opposite quantities combine to make zero and will learn how to subtract rational numbers using a horizontal number line and the additive inverse

In this lesson, students will use T-charts to add and subtract positive and negative numbers.

In this lesson, students will develop the rules for adding integers by using the absolute value of integers and number lines.

Learn how to explain the meaning of additive inverse, identify the additive inverse of a given rational number, and justify your answer on a number line in this original tutorial.

The purpose of this task is meant to reinforce students' understanding of rational numbers as points on the number line and to provide them with a visual way of understanding that the sum of a number and its additive inverse (usually called its "opposite") is zero.

In this task, students answer a question about the difference between two temperatures that are negative numbers.

The purpose of this task is to help solidify students' understanding of signed numbers as points on a number line and to understand the geometric interpretation of adding and subtracting signed numbers. There is a subtle distinction between a fraction and a rational number. Fractions are always positive, and when thinking of the symbol ab as a fraction, it is possible to interpret it as a equal-sized pieces where b pieces make one whole.

In this example, we will work with three numbers in different formats: a percent, a decimal, and a mixed number.

In this tutorial, you will simplify expressions involving positive and negative fractions.

This video demonstrates adding and subtracting decimals in the context of an overdrawn checking account.

Practice substituting positive and negative values for variables.

In this video, we will find the absolute value as distance between rational numbers.

This video will demonstrate how to create quivalent expressions with positive and negative numbers.

This video uses the number line to find unknown values in subtraction statements with negative numbers.

This video asks you to select the model that matches the given expression.

Use a number line to solve a word problem that includes a negative number.

In this video, we figure out the temperature in Fairbanks, Alaska by adding and subtracting integers.

This video demonstrates how to add and subtract negative fractions with unlike denominators.

This video demonstrates use of a number line and absolute value to add negative numbers.

This video demonstrates use of a number line to add numbers with positive and negative signs.

Find out why subtracting a negative number is the same as adding the absolute value of that number.

This video demonstrates adding and subtracting integers using a number line.

A look behind the fundamental properties of the most basic arithmetic operation, addition

Students will be able to see examples of addition of integers while watching a short video, and practice adding integers using an online quiz.

This video contains three examples of interpreting integer expressions in the context of a number line.

Explore negative numbers to represent real world situations in this tutorial.
