Now that learners figured out how to solve for one variable, why not add another? The lesson demonstrates, through examples, how to solve a linear system using graphing, substitution, and elimination.

Students listen to a lecture covering the process of going from one cell to two cells. Using the textbook, students differentiate between meiosis I and Meiosis II. Students work in pairs to create one stage using pipe cleaners, sequins,...

Whether recognized or not, extraordinary women were integral to breaking gender barriers and putting Americans into space. For Women's History Month, explore a series of video clips and biographical information that profile these...

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...

How do you build a polygon from an inequality? An engaging lesson challenges pupils to do just that. Building from the previous lesson in this series, learners write systems of inequalities to model rectangles, triangles, and even...

Young mathematicians examine area of different figures with the same cross-sectional lengths and work up to volumes of 3D figures with the same cross-sectional areas. The instruction and the exercises stress that the two...

Solve a real-world problem of discovering how many doctors and nurses can be hired within budget and building constraints. Using different colored pencils to shade each graph, they then find the intersection points and use these to solve...

Learners find the common point of a linear and quadratic system given a graph of the system. Then they find a specific point located only on the parabola.

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

Students analyze the First Amendment. For this Bill of Rights lesson, students listen to their instructor present a lecture regarding the facets of the First Amendment. Students examine cases which pertain to the freedoms that...

Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...

Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade...

Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...

Create a strong understanding of the relationships formed when parallel lines intersect a transversal. Discuss each type of angle pair and their relationship to each other. 

Sixth graders explore geometric figures. In this geometry activity, 6th graders manipulate properties and relationships of geometric figures to identify objects on the coordinate planes and describe where figures sit on the planes.

Rhombuses, rectangles and squares are have special properties. For this lesson, young geometers investigate and make conjectures about diagonals, angles, and parallel lines of parallelograms. 

Sixth graders find the perimeters of polygons and use perimeters to form polygons. In this perimeter instructional activity, 6th graders study vocabulary associated with finding perimeter such as polygon, line segment, variable, and...

Learn through constructions! Learners examine a translation using constructions and define the translation using a vector. Pupils then construct parallel lines to determine the location of a translated image and use the vector as a guide.

Students explore intersecting lines. In this intersecting lines lesson, students investigate shapes consisting of parallel, perpendicular, and similar lines. Students investigate these lines in shapes around them.

Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

Apply, apply, apply! A measurement lesson applies a number of concepts to help learn a new construction. Scholars learn to divide a segment into n equal parts using a method that uses the Side Splitter Theorem and a method that...

Use the handout as guided or independent practice in drawing a reflection of a rectangle over a line. Three rectangles are provided for practice in addition to a critical thinking question.

A comprehensive lesson on acceleration awaits your physicists and engineers! Two YouTube videos pique their interest, then sample F=ma problems are worked and graphed. The highlight of the lesson is the building of a Lou-Vee air car!...
