Solving Problems Using Triangle Inequality Theorem
Sixth graders investigate triangles and the inequality theorem. They will collaborate in groups to determine the length of a longest side of a triangle. Then relate the size of the triangle to its angles using protractors, yard sticks,...

Making Shapes
Tenth graders construct geometric figures using compasses and protractors.
Curated OER
Classifying and Measuring Angles
Fifth graders explore the three types of angles. In this math lesson, 5th graders estimate the measure of angles and draw the angles using a protractor.

Cover Your Mouth Please!
Second graders investigate how to slow the spread of germs from coughing and sneezing. In this illness prevention lesson, 2nd graders talk about why people cough and sneeze before telling about ways to prevent the spread of germs. They...

Landslides!
Students discover soil and Earth movement by experimenting in class. In this Earth Science lesson, students utilize a stream table, soil, graduated cylinder and water to create a re-enactment of a landslide. Students simulate different...
Curated OER
Designed to Scale
Seventh graders study ratios, scale and distances according to a three dimensional model. For this exploratory lesson students create their own constellation and prepare an oral presentation that describes their model.

My Angle on Cooling: Effects of Distance and Inclination
Learners discuss what heat is and how it travels. They discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
Curated OER
Graphing
Students collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.
Curated OER
The Lunar and Terrestrial Tug of War
Fourth graders, in groups, locate, comprehend, interpret, and evaluate information about celestial bodies that influence ocean tides on Earth. They apply this information through graphic representations.
Curated OER
Measure and Draw Angles
Six word problems provide practice for young geometers to review angles, the angle a of straight line, circles, right angles, and others. I like the approach of these questions; they require thinking and explaining, not just computation.

Shapes and Designs
For this shapes and designs worksheet, 10th graders solve and complete 6 different types of problems. First, they fill in the first two columns of the table show with their shapes. Then, students measure the interior angles of each...
