This short video and interactive assessment activity is designed to teach fourth graders about adding decimals - word problems.

Students will review and practice the concepts of adding fractions. This is a great tool to use for extra practice or review for a test.

This short video and interactive assessment activity is designed to teach fifth graders about adding fractions with different denominators.

This resource from the National Library of Virtual Manipulatives shows students how to rename fractions to have a common denominator and then add them. It is appealing because it visually engages the students by showing them what happens to a unit (a rectangle is used here) as the denominator increases or decreases. As the denominator increases or decreases, the partitions are shown accordingly, and the effect on the numerator is shown as well. This is a convenient, visual way to show students how to manipulate fractions for adding.

In this lesson, students will develop their fluency with addition and subtraction through a real world application of collection data.

This task is a task that will be completed multiple times daily and in fact, ties in perfectly with the first objective. The learners will need to know how to log into the Runner program, how to access customer ledgers, and when the information will need to be inputted as prerequisites to the learning activity. 1-Learning Objective: Employees will add an item to customers ledger unassisted using Runner program.

Understanding adding and subtracting polynomials.StandardsCC.2.2.HS.D.3Extend the knowledge of arithmetic operations and apply to polynomials.

It is important to understand polynomials and to be able to classify them based on the number of terms, as well as recognize the coefficients, and degrees. You must also understand how to perform mathematical operations on them. This seminar will focus on combining polynomials using addition and subtraction. It will be important to understand the rules to make sure you are combining only like terms. You will apply techniques you have learned involving exponents and general addition and subtraction rules. You will use the techniques learned in this seminar to verify solutions to various other types of polynomial problems as you move forward. When adding and subtracting polynomials, you will first identify the like terms to combine polynomials to their simplest form.StandardsCC.2.2.HS.D.3Extend the knowledge of arithmetic operations and apply to polynomials.
