Young mathematicians explore integers. They review adding integers through engaging in mathematical labs. Each lab station is designed to reflect one of the multiple intelligences. Resources for all activities are provided.

Explore nonlinear systems through graphs and algebra. High schoolers begin by examining the different types of quadratic functions and their possible intersections. They then use algebraic methods to solve systems containing various...

Odd or even—fifty-fifty chance? Pupils first conduct an experiment rolling a pair of dice to generate data in a probability lesson. It goes on to introduce mutually exclusive and non-mutually exclusive events, and how to use the...

Why is that graph wider? Pupils learn about stretching and shrinking graphs of square root, absolute value, cubic, and quadratic functions. They study both vertical and horizontal stretches and shrinks in addition to reflections. 

Perform operations using matrices in this algebra lesson. Middle schoolers add, subtract, and multiply matrices. Additionally, they solve systems of equations using matrices.

When and how did the Cold War begin? To answer this question, you will not find a better-organized, in-depth, activity- and inquiry-based resource than this! Executing best teaching practices throughout, each portion of this inquiry...

Can you justify that mathematically?  Help learners see the process of solving as using mathematical properties rather than a set of steps to memorize in the fourth module of a nine-part Algebra I series. The module contains six...

Students review the concepts they were introduced to in a telecast on judicial review. After reading an article, they answer discussion questions and repeat the same procedure for another article. They participate in a debriefing session...

Students are introduced to the concept of judicial review. They read an article about this topic and the Bill of Rights. They answer discussion questions and review as a class.

Students review concepts shown to them in a telecast on the role of the judiciary in a system of separation of powers. After reading an article, they work together in groups to complete a chart on checks and balances. They also discuss...

How are systems related? Build on your pupils' previous knowledge of solving systems of equations by introducing systems of inequalities. Learners explore similarities between systems of equations and inequalities to make a strong...

It's more than just numbers on a line, its an organizational, mental math machine to help learners understand the value of numbers. The tool is handy when introducing positive and negative integers to see their values and...

There's a fine line between a numerator and a denominator! Learners find common denominators in order to add and subtract rational expressions. Examples include addition, subtraction, and complex fractions.

Explore how to graph lines from different pieces of information. Scholars learn to graph linear functions when given an equation, given two points that satisfy the function, and when given the initial value and rate of change. They solve...

Back to the basics: learning how to add numbers. The 17th installment of a 35-part module first reviews addition techniques for rational numbers, such as graphical methods (number line) and numerical methods (standard algorithm). It goes...

Develop a solid understanding of the manipulation of expressions to produce equivalent expressions. Given an expression, pupils rearrange it to create a new one. Their new functions must match the structure of the model expressions.

Shuffle 'em up and deal! Learners practice operations with polynomials using cards they pass around the room. The activity works with pairs or individuals, so it offers great flexibility. This is the fifth installment in a series of 42...

More of a mini-unit than a lesson, these activities lead inquisitors through a survey of oil deposits. In the first part, they read about and view diagrams of sedimentary rock layers that trap oil. Next, they test porosity and...

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

Discover the concept of fractions by using fruit as a model. Scholars discover fractions are part of a whole, similar to the pieces of fruit which are placed in front of them. They then cut up several different types of fruit and discuss...

Build on your learners' confidence in quick addition as they discover strategies to add tens to two-digit numbers. After reviewing counting by 10's, they discuss tactics to add multiples of 10 to other numbers. They visualize how to...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Put the graph into graphing and allow learners to understand the concept of point plotting and how it relates to data. The worksheet provides a nice way to connect data analysis to a graph and make predictions. The worksheets within...

Third graders investigate the events of geological time using a chart called a "Clock of Eras". In this geological events lesson plan, 3rd graders compare a standard clock to a geological clock. In addition, students consider periods...
