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 instructional activity 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...

An informative module highlights eight polynomial concepts. Learners work with polynomial functions, expressions, and equations through graphing, simplifying, and solving. 

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...

Your sixth and seventh graders deepen their understanding of a number line and adding integers in this concrete, hands-on activity. Learners play "Warehouse Puzzle" and then discuss their game strategies and the characteristics...

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....

Designed as a follow-up to the lesson plan titled Watch Out for Parenthesis 1, this activity asks young learners to write an equation for the calculation described with words rather than numbers and symbols. The treasure that 5th...

A great hands-on activity involving adding and subtracting, beginner mathematicians determine how many games can be played with 20 tickets. Instead of tickets, youngsters use 20 counters or linking cubes to represent the amount of...

Ninth graders solve problems involving exponential functions. In this algebra lesson, 9th graders apply their knowledge of exponential properties to add, multiply, divide and subtract exponential functions. They perform these operations...

Students are taught how to add and subtract and use number sense to solve basic math problems. For this addition and subtraction lesson, students are being taught using theories from different philosophers in education. They are given a...

Young scholars explore the factors that can increase the rate of dissolution for a solid. They complete a laboratory exploration in which they compare the dissolution rate of a whole sugar cube to that of a crushed sugar cube in a...

Help your class discover the commutative property of addition with this exploration of the addition table. By folding and coloring the table, a symmetry is found that directs students to an understanding of this crucial mathematical...

Students investigate the concept of fraction and tangible application. In this algebra activity, students use fractions to solve real life scenarios. They convert between fractions and decimals and identify the numerator and denominator.

Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...

Students examine water samples from a local stream. They identify various types of macroinvertebrates found in that water ecosystem and perform a quantitative macroinvertebrate survey to determine the stream's water quality.

Students review the lecture portion of this lesson. Individually, they graph various points on a complex plane and identify conjugates based on their location on the graphs. They complete a worksheet and review their answers to end the...

Students explore the concept of weight and mass and the importance of units. Using a balance, they determine the weight of various objects in the unit of "pebbles" and in grams.
