What does geometry have to do with geometry? The portion of a review series for a math assessment highlights how equation formation is assessed on the test. Pupils use geometric concepts such as perimeter and the sum of the measures of...

Test your third graders with a math review instructional activity, which features problems on square numbers and area. After finding the squares of increasingly large numbers (3-40), pupils solve for the areas of six squares. A great way...

Use the measurements provided on nine different triangles to find the perimeter and area for each. All measurements are in centimeters, making the worksheet simple and straightforward for learners of all levels.

Add a little algebra to the geometry. Class members learn about the Addition Postulate for segments and angles. The pupils use their knowledge of solving equations to find lengths of segments and measures of angles. Individuals apply...

Solving triangles is a breeze. Young boat enthusiasts solve problems involving triangles in the context of sails on a boat. They must apply different strategies, including the Law of Cosines and area formulas.

Stockings make your legs warmer and math more enjoyable. A drag-and-drop interactive has pupils take stockings out of drawers to calculate probabilities. This includes dependent events where the probabilities depend on previous stocking...

Future mathematicians use an interactive to see how changing the size of a basketball court and the size of a region in the court affects the probability that a ball will randomly fall within the specified region. No calculations are...

Learners read two word problems, observe diagrams of four gardens, and find the areas and perimeters. Pupils solve four questions.

Make your classroom interesting by teaching or assessing through tasks. Deepen the understanding of Geometry and motivate young mathematicians. The task uses investigation with tennis balls and their container to prompt learners to...

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

High schoolers explore quadrilaterals in this geometry lesson plan. They will draw a quadrilateral, measure the angles, and find the sum of the measures of the interior angles using Cabri Jr. The interactive capabilities of Cabri Jr....

Students identify chords and angles. In this geometry lesson plan, students calculate the length of the chords inside and outside of-the circle. They differentiate between tangent and secant lines.

Learners explore symmetry.  In this geometry and scientific inquiry lesson, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles.  Learners measure the plane's angles using a...

High schoolers identify triangles as similar or congruent. In this geometry instructional activity, students drag triangles around on the navigator to see the effect of different angles on the shape of the triangle. They discuss angle...

In this geometry worksheet, students calculate the midpoints of polygons using coordinate pairs. They find the  angle bisector, altitude and median of the given triangles. There are 33 questions.

Students 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.

Young scholars investigate proofs used to solve geometric problems. In this geometry lesson, students read about the history behind early geometry and learn how to write proofs correctly using two columns. The define terminology valuable...

To better understand that the intersection point of two lines lies inside a circle, learners use their keen measurement skills. They discuss arcs, rays, tangent lines, and reflex angles. Then, they put their skills to work as they...

In this geometry instructional activity, students find the missing angle that is inscribed inside of a circle. They define vocabularies related to the circle. There are 17 questions.

Students calculate the distance between two points. In this geometry lesson plan, students define the meaning of the distance between parallel lines. They find the point of intersection of other lines.

Find the length of an arc. Learners relate central angles to the area and length of a sector and graph circles on the TI to make predictions.

Three letter-sized mini posters can be displayed in your elementary geometry class when teaching about angles. One provides information about degree measurement and additive properties, and the other two define acute, right, obtuse,...
