Jam on with this multi-faceted activity teaching triangle classification. Start with a learner-paced lesson describing the different qualities of triangles and follow with a fun karaoke session. Also provided are two types...

In this triangle learning exercise, learners identify a set of triangles, labeling as equilateral, scalene or isosceles. A reference web site is given for additional activities. 

In this triangle worksheet, students identify triangles as either equilateral, scalene or isosceles. A reference web site is given for additional activities.

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

Have scholars show what they know with a 20-page assessment aligned to the California State Standards. The test covers concepts such as large and whole numbers, all four mathematical operations, fractions, decimals, geometric figures,...

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

Something for young mathematicians to remember: the sum of any two sides must be greater than the third. Class members investigates the Triangle Inequality Theorem to find the relationship between the sides of a triangle. At the...

Get lost in the classifications. Using the backdrop of the Bermuda Triangle, pupils classify it by angle and side measures. They also learn information about the triangle and its history.

In this geometry worksheet, learners locate 12 geometry vocabulary words that are included in a word bank at the bottom of a word search. They find words such as equilateral, isosceles, and scalene which can be found across, down, or...

Students classify different types of triangles. In this geometry lesson, students identify and use properties of triangles. They differentiate between isosceles and equilateral triangles.

In this triangle worksheet, students label triangles as acute, right, obtuse, scalene, equilateral or isosceles. A reference web site is given for additional activities.

For this triangle worksheet, students identify triangles as scalene, equilateral, right, obtuse, acute or isosceles. A reference web site is given for additional activities.

In this triangle worksheet, students identify a set of 4 triangles as either equilateral, isosceles or scalene. A reference web site is given for additional activities.

In this triangle worksheet, students check the appropriate label for triangles: right, acute, obtuse, scalene, isosceles or equilateral. A reference web site is given for additional activities.

For this triangle worksheet, students check the correct answer, identifying triangles as either right, obtuse, acute, scalene, isosceles or equilateral. A reference web site is given for additional activities.

Junior geometers use hands-on manipulatives to explore and describe the properties and attributes of a fundamental polygon, the triangle. They learn different kinds of angles and their measurements. This well-written lesson plan provides...

 In this geometry lesson, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

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. 

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

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.

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Use this comprehensive pre-instruction assessment tool to focus your teaching where your class needs it most. Multiple choice questions assess your budding geometers' conceptual and vocabulary knowledge, but they do not solve any...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Are your geometry whizzes learning about angles and shapes? This online instructional activity gives 10 multiple choice questions based on images and word problems. Concepts include deducting angle degree, classifying shapes, and...
