Students investigate ways to enhance an object's flying ability.  In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and contrast the two...

Students research Pythagoras and learn how to apply his theorem. They solve real life problems using the theorem and demonstrate knowledge of exponents, equations, and radicals. Students include diagrams in their research papers.

Third graders engage in an enrichment lesson exploring the concepts of area and perimeter. They construct new pentominoes that are 3 times the size of normal ones and then identify the area and perimeter measurements. They then create a...

There's a reason this worksheet is done in groups! Tricky word problems give geometry scholars a challenge as they use prior knowledge about shapes to find the area and perimeter given a few measurements. Students will enjoy discovering...

This resource was written for the younger math learner, but finding the volume of an irregular solid is also a problem for algebra and geometry learners. Based on Archimedes’ Principle, one can calculate the volume of a stone by...

A quadrilateral is drawn on the coordinate plane, and eighth grade geometers find the length of each side and the diagonals by applying the Pythagorean theorem. 

Provide your class some practice with the dimensions of geometric figures. Here you have a set of three different-shaped, stemmed drinking glasses with diameters and heights provided. Math-minded individuals calculate the volume of each....

Students explore geometry by conducing a student measurement activity. In this height instructional activity, students identify their own height by utilizing a tape measure and marking their height on a wall. Students identify their...

In this geometry learning exercise, students solve 6 problems in which an angle is analyzed. From 5 choices, students circle the correct math symbol that names the angle. There are no examples or explanations for the symbols, which would...

In this geometry instructional activity, 10th graders identify the missing angles using the polygons sum conjecture. They measure exterior and interior angles using their angle theorems. There are 63 problems.

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson plan, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional...

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...

Learners identify triangles as similar or congruent. In this geometry lesson, students drag triangles around on the navigator to see the effect of different angles on the shape of the triangle. They discuss angle similarity and angle...

Learners will differentiate between inscribed and central angles in this geometry lesson. They answer questions dealing with circles as they relate to inscribed triangles and angles. This assignment includes a printable worksheet.

High Schoolers investigate the perpendicular bisector of a line segment. They use Cabri Jr. to construct the perpendicular bisector of a segment. The dynamics capabilities of Cabri Jr. allow your learners to observe the lengths of the...

High schoolers differentiate lines and angles using betweenness in this geometry lesson plan. They differentiate angles and lines using Cabri Jr. and analyze the data and make conjecture.

High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...

Young scholars identify the relationship between angles and arcs. In this geometry lesson, students rotate and move the circle around to create different arcs on the TI-Navigator. They differentiate between major and minor arcs.

Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.

Students explore similar objects. They participate in a series of hands-on, multimedia and online activities to examine how the edge length affects the angle measures, perimeters and areas of similar regular polygons. Students find the...

In this geometry worksheet students explore similar polygons and determine measure of missing sides and angles. Students use indirect measurement with similar triangles and determine the area and volume of similar figures. The seven...

Students graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They classify the lines as parallel or perpendicular and write an equation of a given line.

Students investigate an accident and relate it to math. In this trigonometry lesson, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.

For this geometry worksheet, 10th graders apply the properties of parallelograms to find the indicated angle measure or segment length. The two page worksheet contains twenty-two problems. Answers are included.
