Mixed numbers can be added conceptually, algorithmically, and physically. Have the class visualize mixed numbers by adding fraction bars together. They then discover the algorithmic process that simplifies adding mixed numbers. Finally,...

There is more than one way to add mixed numbers. This worksheet asks 5th graders to find and record two ways. The purpose is to help pupils realize there are different ways to reach a common solution in math. The two most common ways are...

Seventh graders practice measuring skills as they add mixed fractions. In this fractions lesson, 7th graders measure the distance from their wrist to the tip of their finger, record the measurement, and repeat this procedure with other...

In order to create some tasty fudge, learners must adapt a recipe. Using a recipe for fudge, ingredients must be correctly converted using fractions. If one fraction is incorrect, the fudge will reveal it! Although you will only make one...

Common Core mathematical practices require that young mathematicians not only know how to add fractions with unlike denominators, but also to recognize when adding fractions are appropriate for the word problem. Fifth graders are given...

A simple question, with a not-so-simple answer. Working with whole and mixed number measurements in inches, feet, and yards presents a problem with many possible solutions. A great activity that challenges the minds of young...

Using a real-world example, this problem illustrates the thought process that learners need to engage in to understand adding mixed numbers with common denominators. First by looking at estimation, and then by drawing models that...

Learners convert between fractions and decimals. In this algebra lesson, students investigate fractions and differentiate between largest and smallest fractions. They add fractions and decimals using a common denominator.

Students work with the concept of equivalent fractions. In this equivalent fraction worksheet, students double a recipe, triple a recipe, and reduce a recipe for Tiger BITES by one-half and one-quarter. They apply multiplication and...

Sixth graders solve and analyze fractions. In this algebra lesson, 6th graders solve fractions using addition, subtraction, multiplication and division. They work in groups and do peer-review.

The 15th lesson plan in the series of 24 helps your classes understand the ppm (part per million) unit of measure. First, scholars experiment with food coloring to determine concentrations before applying their findings to calculate...

Here is one of the better lessons I've come across on how to teach fractions and decimals. This instructional activity does a great job of showing how these two mathematical representations of numbers are interrelated. Some excellent...

Recipies are a natural medium for using fractions in real-world problems. This delicious activity has learners adapting the ingredients for coconut and chocolate chip macaroons, a Passover treat, for fewer and more cookies than the...
