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...

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...

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...

Explore properties of integers! In this algebra lesson plan, pupils add, subtract, divide and multiply using integers correctly. They differentiate between rational and irrational numbers.

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...

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...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson plan can stand alone, but is best used as part of...

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...

Can you add variables if you don't know their value? Using an empty number line, scholars first locate the position of the difference, sum, product, and quotient of two unknown integers. Later problems mix operations as well as add...

Investigate expected value as a long-run average. The eighth installment of a 21-part module has scholars rolling pairs of dice to determine the average sum. They find aggregate data by working in groups and interpret expected value as...

Learners create a model volcano in groups, and discuss what each part of the model represents as they go along.  For this volcano lesson, students come back together as a whole group and discuss what group did the best work,...

Learners build a salt dough volcano. They the salt dough using the following ingredients: flour, salt, and water. Students mix flour and salt in a container and add water and mix until the dough is smooth. They then make the volcano....

Students experiment to determine if yeast is a microorganism. In this yeast blowup lesson plan, students mix yeast with other ingredients and observe the results by using a balloon. Students adjust the amounts of the ingredients and test...

Students 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 model the soils layers using Oreo's. In this lesson students use their favorite food items to create a model of soil layers. A discovery lesson from a youth camp is adapted for classroom modeling and discussion of soil...

Students observe projectile motion and calculate the speed of a baseball based on the time and distance traveled. They record the time, measure the distance, and draw the path of the ball's travel on a data table.

Students relate recycling to waste reduction. In this science lesson, students talk about the environment and how recycling certain natural resources actually saves on energy.  They also discuss what type of recycling causes...

Art can mimic life, and animals are always interesting subjects. Learners create large soft sculptures (stuffed) birds using paper, paint, and other basic collage materials. They view images of birds, and discuss bird traits and shapes....

Learners explore Literal Equations. In this literal equations lesson, students use the Internet to connect to links and solve linear equations. Learners investigate, analyze and record their findings on various activity worksheets.

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.

Young scholars explore consumer math by participating in estimate exercises. In this currency lesson, students identify and define each piece of U.S. currency and their value to the monetary system. Young scholars complete several money...

Students complete a variety of labs to help them explain how energy affects the changes in states of matter. They also be required to collect and record data, graph data, and apply interpretations of that data.
