Students investigate proofs used to solve geometric problems. For this geometry lesson, students read about the history behind early geometry and learn how to write proofs correctly using two columns. The define terminology valuable to...

Middle schoolers compute the area of a rectangle.  In this area lesson, students measure the sides of rectangles and squares.  They cut figures, measure them, and determine the area of each given figure.  Middle schoolers...

Students find the volume of rectangular prisms.  In this volume lesson plan, students use a formula to find the volume of rectangular prisms.  They discuss the definition of volume and draw rectangular prisms.  Students...

Students analyze graphs of two equations. In this algebra instructional activity, students rewrite word problems as linear equations. They graph their solution and compare and contrast the two items being represented.

Students explore conics using four different graphs. In this calculus instructional activity, students analyze parabola, hyperbolas, circles and ellipses. They find the directrix and discuss how they relate to each type of graph.

How do you make a penny grow to $5,000 in just 15 days? Use the examples in this lesson to explore the concept of exponential growth and its comparison to linear models. Pupils come to understand that exponential growth eventually...

Wow! Put on that thinking cap and solve multi-step equations. To solve equations, learners review the use of the distributive property and combining like terms. This three-day lesson comes with about 20 pages of worksheets, warm-ups,...

Groups explore sets of 10 items in two varieties (i.e. 3 white buttons and 7 black ones, or 5 bears and 5 bunnies). They brainstorm about their objects, write math sentences to represent what they have, and report their discoveries...

Pre-algebra protégés critique a graph depicting Tom's trip to the bus stop. They work together to match descriptive cards to distance-time graph cards and data table cards, all of which are provided for you so you can make copies for...

Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

Students explore basic algebra formulas. In this introductory algebra lesson, student use basic algebra formulae to simplify expressions that include 1 or 2 operations.

Fourth graders complete a role playing activity to build understanding of number concepts. They use Algebraic Closure throughout six operations to better comprehend and review basic number theory. They utilize a worksheet imbedded in...

Ninth graders examine mathematical patterns. In this algebra lesson, 9th graders collaborate to think outside the box and share solutions to problems they have encountered. Students use popsicle sticks to solve various building problems...

For this algebra and patterns practice worksheet, learners sharpen their problem solving skills as they solve 6 story problems.

Through discussions and journaling, classmates determine methods to associate types of functions with data presented in a table. Small groups then work with examples and exercises to refine their methods and find functions that work...

Building upon previous knowledge of sequences, collaborative pairs analyze sequences to determine the type and to make predictions of future terms. The exercises build through arithmetic and geometric sequences before introducing...

In statistics, probability rules—literally! Learners use their previous knowledge and explore a set of rules for conditional probability, independent probability, and complements. Given different scenarios, they must determine what type...

All data is not created equal. Scholars examine the different types of studies and learn about the importance of randomization. They explore the meaning of causation and when it can be applied to data. 

There's a function for that! Scholars examine real-world situations to determine which type of function would best model the data in the 23rd installment of a 35-part module. It involves considering the nature of the data in addition to...

Why do we have to do so much work? Scholars learn how to set up bar models to represent a situation involving work. They use these bar models to help set up equations with rational coefficients to solve the problem situation.

Why do I have to do bean counting if I'm not going to become an accountant? The 24th installment of a 35-part module has the class conducting experiments using beans to collect data. Learners use exponential functions to model this...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

The power to solve exponential equations lies in the resource. Scholars first learn how to solve exponential equations. An activity matching cards with equations, intermediate steps, and solutions strengthens this skill.
