Congruent Trianges - Is This Enough Information?
Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.
Curated OER
Tri this Angle!
First graders draw and describe various types of polygons. they investigate their own environments for examples of polygons. After reading the book, The Greedy Triangle, they discuss everyday objects that are polygons. They create shape...

Measurement Investigations 1
Fifth graders find perimeters, areas, and volumes of everyday objects and state the precision. They work in small groups in order to take measurements, perform calculations, and write a group report about the investigation.
Curated OER
Terrific Tessellations
Students construct tesselations that fosters their ability to create, transform, and critique their own piece of work. This allows them to become aware of repeated patterns in math, and connect these patterns to artwork.

Math is Everywhere: Part 2
Second graders identify shapes and measurements in everyday life. In this measurement lesson, 2nd graders locate rectangles in their classroom and use standard and nonstandard forms to measure them. Students view a video clip...
Curated OER
Watch It Slide!
Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.

Congruent Triangles - Is This Enough Information?
Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.
Curated OER
Parallel and Perpendicular Lines
Fourth graders create a dance with a partner that shows parallel and perpendicular lines. In this lines lesson plan, 4th graders create symmetrical designs and line pairs with their partner.
Curated OER
Ovals, Rectangles, Squares, and Triangles
Students identify geometrical shapes displayed in photographs of everyday objects in a metropolitan setting.

Swinging on a String
Young scholars explore how pendulums work and why they are useful in everyday applications. In a hands-on activity, they experiment with string length, pendulum weight and angle of release.
Curated OER
Slide Right On By Using an Inclined Plane
Fourth graders examine the simple machine known as a plane. They build their own pyramid and identify the role of screws. They participate in a hands-on activity in which they determine the angle in which to make it easier to pull.
Curated OER
Geometric Fractals and the Chaos Game
Students define fractals and patterns. They explore how a seemingly random process can result in a pattern. Students practice probability and fractions skills by playing the chaos game online.

The Way Levers Work
Fifth graders discover the rules by which the lever slants and balances. They determine that there are a great many tools that employ the lever principle even in their ordinary environments. They consider how to use objects easily...
Curated OER
Seesaws
Students make direct comparisons between objects using balance and spring scales. They also are encouraged to estimate which object is heavier by holding the objects before using the balance scales. Comparing the masses of objects is the...
Curated OER
Translations, Reflections, and Rotations
Students are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.
Curated OER
Terrific Tessellations
Students create, transform, and critique their own piece of artwork. In doing this lesson, students get more experience working with angles, lines, and measurement. They gain experience seeing, and creating their own patterns and shapes.
