New ReviewA short video describes how to find line symmetry in figures. It works through several different examples, including a few with multiple lines of symmetry.

Provide a large amount of information in a short statement. A segment of a playlist on basic geometry introduces the notation to denote congruence between two figures. The video shows how to read corresponding parts from a congruence...

Build up the basics of geometry, one point at a time. The segment in an extensive playlist on basic geometry provides the definitions of the essential building blocks of geometry. Using drawings, the video shows examples and descriptions.

Flip, turn, and slide to get there. With the aid of hands-on materials, pairs transform a figure from one place on the coordinate plane to another. They determine a sequence that will move one figure to another and present different...

Search high and low for geometry. Using cameras, groups scour the school campus looking for geometric figures. The goal is to collect the most points by finding the higher scoring geometric figures for each category.

Can you define that basic figure? Building upon the undefined terms in geometry, the lesson defines basic geometry figures. The resource defines line segment, ray, angle, perpendicular lines, and parallel lines.

Patty paper isn't just for separating meat. The lesson uses an inexpensive way to experiment with rigid transformations. Pupils use patty paper to create images after a translation, reflection, and rotation. Given a formative assessment,...

Geometry begins with a point. The video introduces the concepts of points, lines, and planes. Using diagrams, the presenter includes how to name the objects along with how to write the names. Previewing the concept of 3-D space ends the...

Given a certain amount of points, how many line segments can you connect between them? How many close geometric figures can you create? These are the types of questions learners are asked to solve in a assessment-based worksheet.

An assessment presents two triangles on a grid along with assumptions of the locations of the vertices. Pupils describe a sequence of transformations that will transform one triangle onto the other. 

No umbrella? No jacket? No problem! Physics scholars learn the mathematical advantage to running in the rain. The narrator illustrates the factors of top rain and side rain and how position and speed influence these factors.

Develop a precise and clear definition. Pupils draw and label a circle. They develop a precise definition of the circle using references to the center and distance from the center. 

Assess the class' ability to solve problems involving area, surface area, and volume with a six-question assessment that presents problems covering aspects of calculating measurements of 2-D and 3-D figures. Class members use the...

Pick up a resource on Pick's Theorem. Individuals watch a video explaining how to find the area of a polygon drawn on a lattice using Pick's Theorem. The film also shows a proof of the theorem using the Euler characteristic and algebra.

The ABCs of math are so important. Find commonly used math terms in a 42-page packet. Each page has the word, a place to write the definition, and a place to give specific examples of the term. A must-have for all math classrooms!

Cut and paste a facade study. After viewing a presentation on facades and facade studies, scholars apply their newfound knowledge to various buildings. They then complete a puzzle where they cut and paste a facade study of the Sta. Maria...

Discover how to analyze architecture from a geometric standpoint. The fourth installment of an 11-part unit on architecture first provides a presentation on axis, balance, basic form, formal, pattern, proportion, symmetry, and tripartite...

Two-axis rotations ... twice the fun as one-axis rotations! The last installment of a five-part module teaches scholars how to conduct two-axis rotations. They create isometric drawings before and after the rotations.

Investigate the effect of one-axis rotations on geometric figures. Scholars learn to use snap cubes and the right-hand rule to draw figures after rotations about the x-, y-, or z-axes. They try their hands at examples created by the...

How can your draw three-dimensional figures on paper? The lesson shows pupils how to draw orthographic projections of three-dimensional figures composed of cubes. After viewing a PowerPoint presentation, they practice this skill with...

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...

Can you see your class working on spatial visualization? The first installment of a five-part module introduces the concept of spatial visualization and provides a 12-question diagnostic assessment to test spatial visualization skills....

Boxing takes on a whole new meaning! The second installment of the three-part series has groups create lidless boxes from construction paper that can hold the most rice. After testing out their constructions, they build a new box....
