The Common Core is intended to help all children meet high academic standards. Here is a Common Core designed lesson that is intended for learners with communication or language difficulties. The lesson is written in a narrative style...

Challenge your scholars to show what they know about the Law of Sines, Law of Cosines, and inverses. The six-question assessment is the last in a series of 16. Pupils find the area of triangles and show that the Law of Sines and Law of...

Add up areas of squares to discover the pythagorean relationship. Small groups create right triangles with squares along each side. They calculate the areas of each square and notice the relationship. Groups construct other types of...

In this problem solving strategy worksheet, 6th graders solve a story problem using the strategies of understand, plan, solve, and look back.

Students investigate the concept of the Pythagorean Theorem. After conducting independent practice to find the hypotenuse of a triangle, they work with the teacher using examples in the lesson plan. The direct instruction is delivered...

Students use the Pythagorean theorem to discover the relationships between the lengths of sides of a right triangle. In this right triangles lesson plan, students use their reasoning and mathematical skills.

Students review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.

In this geometry worksheet, students look at a picture of downtown landmarks and identify different shapes, lines, and more. Students identify 18 items.

Students explore the history of Pythagoras and his contributions to mathematics. In this middle school geometry lesson plan, students use one inch tiles to investigate the Pythagorean Theorem and to find the length of the sides of a...

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

Eighth graders explore the Pythagorean Theorem. They use Geometer's Sketchpad and explore features of various figures. Students use the software to build a figure using the given measurements.

Young scholars use the inequality theorem to solve triangles and their properties. In this geometry lesson, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to...

For this geometry worksheet, 10th graders apply the Pythagorean Theorem as they determine the length of the missing leg or hypotenuse in right triangles.  The one page worksheet contains twelve questions.  Answers are...

Fifth graders write and illustrate books to make a class library of math term books. They utilize vocabulary associated with geometry to make their books. For example, one character may be, Mr. A Cute.

Students identify triangles in the real world and construct their own triangle using drinking straws. They explore abstract triangles and find additional geometric shapes such as trapezoids. Students discuss similar shapes and examine...

Students engage in a lesson that is about the classification of triangles and the mathematical proofs involved in working with them. They work on a variety of problems that are created by the teacher with the focus upon the importance of...

In this right triangles worksheet, 10th graders solve and complete 12 various types of problems. First, they solve for x given each of the right triangles shown. Then, students determine the length of the shorter diagonal given the...

In this triangles worksheet, students solve 4 multiple choice problems. Students find the centroid, orthocenter, incenter, and circumcenter or various triangles.

Learners study West Virginia quilts. In this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Students explore differents types of triangles and quadriaterals. In this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference between...

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Learners view a segment of Futures With Jaime Escalante showing the application of math in basketball, and they try to find some of these applications in a tape of a game played by their home school. This fun lesson should be very...

Students explore the global grid system. For this globe lesson, students identify latitude and longitude lines and how these can tell the coordinates of any place. They use the Internet to find the exact coordinates for their town. 

Students classify, flip, slide, and turn a quantity of quadrilaterals.
