Pupils multiply by one-digit whole numbers.

Investigate simplifying rational expressions. Learners define rational expressions, review how numerators and denominators are polynomials and complete several problems using a checklist to ensure they don't skip any steps. Work can be...

Young scholars practice multiplying decimals and/or mixed numbers, explore the effects of multiplying decimals and mixed numbers, and practice predicting the effects of multiplying a number by a decimal or mixed number.

Student are assigned one of the sections on whole numbers. After reviewing the content, they teach their assigned sections to other class mates. They publish their findings on a PowerPoint slide show to use when they teach their section.

Learners find percents and unit price using popcorn.

Students, in groups, determine the volume of a box large enough to hold a million dollars. They calculate the dimensions of a bill and the volume of the money.

In this online math worksheet, high schoolers factor a series of trinomials given specific equations. This excellent resource allows the students to check their answers and to get "hints" should they run into difficulties.

Need more detail in showing your class how to solve two-step equations and proportions? This lesson plan outlines the steps young mathematicians need to solve simple equations and check their results. 

Young scholars explore the concept of adding integers.  For this adding integers lesson, learners simulate the battle of the 300 spartans at Thermopylae.  Young scholars use colored game pieces to represent positive and...

Seventh graders create a graph of their Christmas gifts. They develop categories, compute fractional and decimal parts for each category, identify the number of degrees to represent each fractional part, and create a circle graph to...

In this exponent rules worksheet, students simplify 56 negative exponents and scientific notation problems.  Students use exponent rules to simplify each problem.

Second graders practice the multiples of three as an introduction to multiplying by three.

Eighth graders demonstrate the mathematical components of a scientific problem as well as illustrate how real world problems can be solved using math. They demonstrate math skills such as rate calculation, graphing, and linear equations.

Second graders use a number line to practice subtraction.  In this subtraction instructional activity, 2nd graders use a number line to count backwards.  Students participate in mad math activities and solve problems.

Students explore the concept of solving two-step equations. In this solving two-step equations lesson, students watch a short video about solving equations. Students view a PowerPoint presentation about solving two-step equations....

Students listen to Gill's story and determine how many number points she has. They then find the number of points their own name has and get into groups where all the name points are the same.

Third graders create a box big enough to hold a million dollars. This is a project fun to do near the winter holidays with inexpensive gifts included in the boxes. This hands-on lesson very effectively demonstrates the concept of volume.

Students sort Lego Duplo pieces after determining the attributes to classify them by. They work in pairs to sort a group of Duplo pieces and explain their process to others.

Students listen to the problem being read. They then brainstorm possible approaches and are encouraged to plan ways of recording their work so that others examine what they have done and share their findings.

Students learn about the concept of adding algebraic fractions by exploring a tutorial. They can then test their knowledge by taking a ten question assessment that increases in difficulty as they correctly answer questions.

This site provides students practice with the concept of algebraic fractions. Students can learn about the topic by completing an interactive tutorial. Students can then take a ten question timed test to practice the skill.

Here is a site that clearly and thoroughly explains adding algebraic fractions (rational expressions) both with common denominators and with different denominators. There are example problems solved, problems for the student to attempt,...

Use this site to learn how to add and subtract algebraic fractions, even if there aren't common denominators. Provides plenty of examples.
