The purpose of this task is for students to reason about base-ten numbers on the number line in a way that will require them to use what they know about place value. Students first represent addition and subtraction on the number line in...

Students take a quiz over the concept of integer opposites, also known as additive inverses. After answering each question they are given feedback. Hints are available but affect the score. If students are still struggling with the...

Practice finding the missing value in an addition or subtraction equation involving negative numbers. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Students will learn that there are multiple ways to solve math problems, such as drawing a picture, using counters, using fingers, using a number line, and memorizing facts. The teacher writes a simple addition problem on the whiteboard...

Students can practice addition and subtraction of 100 on a number line with this activity.

Get independent practice adding integers. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

Use the number line to recognize the opposite of a number.

In this lesson, students use a graph to choreograph a dance figure. Media resources and teacher materials are included.

Second graders demonstrate comfort with addition, but show less ease with subtraction. Repeated practice with subtraction is necessary to build fluency.
