Young scholars use the data from USA TODAY Snapshot "World population milestones" to explore and explain the trends in the world population.

Students work with large numbers when determining the height of a stack of $20 bills.

Students read about the changes in the "new money" and then create a graph to represent various combinations of currency produced.

Factor polynomials using electronic manipulatives. Your class will create a spreadsheet in excel and use it to multiply and perform basic operations and solve problems correctly. They create a visual to go along with each multiplication...

You and your class will like this lesson on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and then...

Students explore the concept of equivalency. In this equivalents lesson, students use pennies to show equivalency as they divide them into groups. Students also convert the pencils into decimals and fractions.

Students explore the concept of ratios. They observe a website of Trident Gum that gives a real life example of ratios. Students practice ratio problems in three forms. They express ratios as a proportion and solve proportions using...

Fifth graders become familiar with problem solving strategies of guess and check and working backwards. They demonstrate the basic concepts of addition, subtraction, multiplication, and division using a math sentence.

Fourth graders explore negative numbers with this resource. They discuss positive and negative numbers by counting who is present and absent, placing numbers on a number line, and graphing temperatures. Using a variety of activities,...

Vectors and their connection to motion. A video will be presented to provide information for the class to use methods of solving vectors with and without grids. Real-world physical concepts will be explored in reference to vectors.

Pupils memorize four key decimal values for quick and accurate conversion. They convert decimal foot measurements to inches and fractions using math tables, computation or memorization. They memorize decimal foot conversions.

Fourth graders use inductive reasoning to find algebraic patterns in geometric figures. They use technology (i.e., calculators, computers) and manipulatives to discover number patterns involving geometric concepts. They solve concrete...

Introduce elementary students, grades 3-5 to the concept of equivalent fractions. Each student folds a paper in half and color one of the equal parts of the paper. They use this paper to define numerator, denominator and the idea that a...

How do you solve for a variable? This slideshow provides definitions, key concepts, and guided practice to teach learners how to solve literal equations for a specified variable.

How do you solve linear equations? Learn how to solve simple linear equations by applying properties of equality in this instructional slideshow. The materials include step-by-step instructions and key concepts to support understanding.

Students get the opportunity to investigate the concept of data collecting. They explore how to tally and read a bar graph. Vocabulary about data is also be included. At the end of the lesson, individual students collect data independently.

Most middle schoolers probably feel that quilting is at best an activity left to their grandmothers. This lesson uses the Zome modeling system to get them to realize how shapes in quilting are really tessellations and repeating patterns....

Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...

Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.

Students explore multiplication concepts.  In this multiplication lesson, students define "array" and draw several arrays to represent multiplication number sentences.  Students construct arrays on the computer using MathKeys...

Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...

Learners explore the concept of volume. They develop formulas for volume of prisms. Then use their formulas to find missing dimensions of various prisms such as height, length, width, radius, and diameter.

Geometers find the area of four circles given their circumferences. Circumference is presented in the form of "numeral (diameter) x pi"; the answer key shows solutions as  "numeral (radius squared) x pi," so computation is...
