Factor in different strategies in a lesson plan for factoring quadratics. Young mathematicians first create tables and area models to factor quadratic trinomials into two binomials by guess and check. Learners then investigate how they...

In this area of shapes unit, upper graders participate in hands-on problem solving activities to find the formulas for the area of a parallelogram, a triangle, and a trapezoid. They manipulate the geoboard to explore relationships among...

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

How's the weather today? Elementary and middle schoolers plan severe weather awareness day in this lesson on research presentations. They present their research reports, along with their action plan and any other associated products...

It's time to put the plan into practice. Using their plans from the previous lesson, scholars create multimedia and visual displays for their opinion speeches. Next, they watch videos of speeches and use a presentation rubric to evaluate...

Using a concept attainment approach, learners identify surface area and volume by sorting examples (photos) that depict each concept (positive)  from those that don't (negative). Then as a class, they develop definitions of each...

A deceptively simple question setup leads to a number of attack methods and a surprisingly sophisticated solution set in this open-ended problem. Young geometers of different strengths can go about defining the solutions graphically,...

This is a good model for learners to visualize triangles of the same base and height. They can can begin to comprehend that these triangles will have the same area no matter how the triangle is drawn. It is part of a series of resources...

Presenting ... the gold standard for a lesson. Learners first investigate a task maximizing the area of a plot for gold prospecting. They then examine a set of sample student responses to evaluate their strengths and weaknesses.

As Ken Jennings said, "There's just something hypnotic about maps." Certainly, the longer you look at them the more you can learn. In this project-based learning lesson, individuals study both historic and present-day maps of...

Should we continue to spend money on nanotechnology? Groups engage in a problem-solving unique process around the newly emerging research field of nanotechnology. In order to propose a solution, the groups must research nanotechnology...

Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

Give your classes practice at modeling using quadratic models with a resource that uses area and integer problems to allow individuals to create second degree polynomials. Young mathematicians solve equations using factoring and then...

Ninth graders demonstrate application of area, surface, and volume. They apply formulas to a model of the classroom so they can determine the volume and surface area of the classroom.

Students study area and quadrilaterals. In this multiplication and area activity, students use Polystrip models to change rectangles to form different parallelograms. Students find the area of the models use a Geometer Sketchpad to find...

Factor polynomial functions that have two and three terms. Using Algeblocks, your class will create models to show their understanding of these concepts.

Multiply your understanding of multiplying fractions. A short lesson teaches pupils how to multiply fractions. By using fraction models, they get a better understanding of the concept.

Young learners need practice speaking comfortably in front of others. Post a list of oral speaking tips on the board during this unit. Over a week-long period, they create a story from their interview sheet and present it to the class....

What are characteristics of a planet? With this plan, learners investigate the characteristics of the planets in our solar system. They gather research of the nine planets by using the Internet and other research tools. Then they create...

If shapes have the same area, do they always have the same perimeter? Learners explore the relationship between the area of square units and their perimeters in a hands-on activity. Observations are recorded, and they begin to recognize...

Middle and high schoolers investigate all the different places in math that square root is present. In this geometry lesson plan, pupils discuss square roots as it relates to a right triangle and construction. They go over altitude,...

The humble soda can gets the geometric treatment in an activity that links math and science calculations. After a few basic assumptions are made and discussed, surface area calculations combine with density information to develop an...

Third graders create posters of heroes and present their findings and what they think it means to be a hero. In this role models lesson plan, 3rd graders compare heroes and describe their characteristics.

Seventh graders complete activities to further their understanding of area formulas. In this area lesson, 7th graders watch as the teacher uses Polystrips to model parallelograms. Students find the area of a rectangle and answer...
