There's just something special about lines in algebra. Introduce your classes to linear equations by analyzing the linear relationship. Young mathematicians use input/output pairs to determine the slope and the slope-intercept formula to...

Here is really nice set of resources on scientific notation. Eighth and ninth graders explore the concept of multiplying and dividing in scientific notation. In this multiplying and dividing numbers in scientific notation...

Young scholars convert quadratic functions from standard form to vertex form. In this algebra instructional activity, students solve polynomials using synthetic and long division. They derive and apply the remainder theorem and factor...

Study Islamic achievement in mathematics by exploring the six standard forms of equations. High schoolers will review the six forms of equations of Al-Khwarizmi. They solve equations using different forms. Links and resources are...

It doesn't get simpler than this. Scholars first learn to simplify radicals by determining the prime factors of the radicand. The lesson plan progresses to simplifying radicals involving algebraic expressions in the radicand.

I can multiply, so why can't I add these radicals? Mathematicians use the distributive property to explain addition of radical expressions. As they learn how to add radicals, they then apply that concept to find the perimeter of...

Scholars view the video, "Donald Duck in Mathmagic Land," and discuss examples in nature which have proportions of the golden ratio. They measure and record different body lengths from a worksheet and convert the ratios to equivalent...

Students solve equations through trial and error. In this algebra lesson plan, students first estimate their answers and then calculate it to check their work. They solve problems involving roots and integers.

Students solve quadratic function by completing the square. In this algebra activity, students use the quadratic formula to factor quadratics and find the roots. They graph the parabola and identify its properties.

Students develop an equation for finding the volume of a commonly known piece of candy (M&M, Hershey's Kiss, Tootsie Roll Pop, Life Saver, etc.) by using calculus.

Students perform mathematical operations on complex numbers. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice performing operations on complex numbers.

Students practice visualization as a strategy for reading and comprehending math word problems.

Introduce your middle and high schoolers to the correct use of quotation marks. They identify examples of correct and incorrect quotations in magazines and edit a paragraph in groups. Use this lesson as a way to reinforce proofreading...

Fourth and fifth graders study the Pythagorean Theorem and apply it to find the missing side of a right triangle.

A lengthy narrative about Pythagoras and his students precedes an activity in which your young mathematicians practice using the Pythagorean theorem to solve three problems about flight and distance. Answers are provided. 

Discuss scientific notation with this mathematics lesson. Middle schoolers predict which problem is bigger of two numbers. They analyze the problems by observing the powers of 10 in order to decide which is bigger. This appears to be an...

Does it? Kids find the perimeter and area of different shapes to assess whether their rectangle has guts. In addition to finding the area of a rectangle, learners work to find the area of a trapezoid. All worksheets are included. 

Upper graders use the properties of right angle trignonmetry to measure objects such as the school flagpole. They solve real world problems using these properties.

In this math worksheet, students must rationalize the denominators to solve radical expressions. Students square terms for fourteen of the problems. The other six problems involve different roots (3rd, 4th, or 5th roots).

Students research Babylonian mathematics. They calculate simple surd numbers. Students find the fractional form of rational numbers expressed as decimals. They work with numbers in base 60.

Students work together to discover the flow rates of faucets and rivers. They relate their results to engineering and applied science concepts. They make predictions on the flow rate of a nearby river in their local community.

In this Algebra I worksheet, 9th graders represent verbal expression algebraically and evaluate the expressions for the given replacement values of the variables. The three page worksheet contains the instructions for the card game and...
