Young mathematicians to the rescue! Pupils use an interactive to find lengths relating a ladder against a building. The problems involve determining how long a ladder must be to reach a given floor to what floor can a given ladder reach.

Speed up your pupils' understanding of derivatives. Two cars travel in perpendicular distances to each other. With the aid of the interactive, learners visualize the situation. Pupils use the derivative to calculate the instantaneous...

Rise to the challenge of trigonometry. Watching a video of an ascending funicular at the Sacre Coeur in Paris sets the stage for a challenging task. Young mathematicians use a given diagram, along with the concepts of slope and...

Problem solve across the content standards. The presentation slides provide 19 sample items from the Smarter Balanced high school assessment. Items illustrate Claim 2, problem solving, of the test and are drawn from all the high school...

In this trigonometry learning exercise, students use the sine and cosine law to solve problems. They investigate obtuse triangles using these laws. There are 40 questions.

Students investigate the relationship of triangles with its sides and angles. In this geometry instructional activity, students create visual on the graphing navigator as they study triangles. They move the sides around to create...

In this geometry worksheet, 10th graders answer questions about right triangles by identifying the 3 sides of the triangle. They analyze the different shapes of polygons and relate them to right triangles to find the sides using the...

For this geometry worksheet, 10th graders solve problems that are based on the theorems associated with perpendicular and angle bisectors of a triangle.  An application on the coordinate plane is included.  The one page...

Students explore the design of sailboats. In this sailboat lesson, students recognize right triangles and find the missing side of the triangle. Students solve word problems and draw diagrams. Students relate the triangles to sailboats.

Students investigate geometric shapes. In this geometry lesson plan, students read the book The Greedy Triangle and define the shapes mentioned in the book. Students make the shapes by using their bodies.

In this geometry worksheet, students practice finding the measure of 4 different angles. Students work independently as they refine their ability to correctly calculate the measure of an angle.

Four fabulous worksheets are included in this resource, all having to do with the measurement of angles. On the first, anglers will use a protractor to determine the degrees of 10 different angles. An arc is drawn on each. On the second,...

Students calcute distances using trigonometry and angle measurements. They estimate the width of the Trig River, measure it and compare their results with their classmates. They collaborate with a group to research and find the results.

Break out the slide whistles, triangles, and tambourines. It's time for a punctuation lesson. This richly detailed plan is loaded with ideas and activities for using rhythm instruments to accent the punctuation in folk tales. A...

In this addition activity, students fill in the numbers inside 7 penguins by adding together the 2 penguins right above each one. Students figure out the sums for each penguin with Pascal's triangle.

Scholars first learn the definitions of the sine ratio, the cosine ratio, and the tangent ratio. After mastering these definitions, they use the new information to solve triangles.

Sew up learning on writing rules for patterns with an assessment task that has pupils investigate the number of triangles needed for cushions of different sizes. They then use the data to generate a rule for a cushion of any size.

Prove the Pythagorean Theorem using multiple informal proofs. Scholars first develop an understanding of the origins of the Pythagorean Theorem through proofs. They round out the lesson by using the theorem to find missing side lengths...

Your class may believe that geometry is a trial, but they don't know how right they are. A thorough math lesson combines the laws of logic with the laws of geometry. As high schoolers review the work of historical mathematicians and...

Here is a very interesting way of studying triangles and polygons. Pupils work together and use pieces of string to create a variety of shapes. Depending on how many kids are manipulating the string at any one time, the number of...
