Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...

Students explore Geometry with Twizzlers Candy, pipe cleaners, paper, pencils, and protractors. They manipulate these items to create different angles introduced by the teacher.

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...

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,...

Remove any ambiguity about using a helpful resource. Individuals use an interactive to find the number of triangles that fit given conditions. They find that some conditions can result in more than one triangle in the ambiguous case.

There is no such thing as someone who is not artistic when using this app. In fact, this is the type of app that makes you want to go out and buy a tablet computer. Whether you have a creative lesson planned, or just need a place to take...

Students observe brine shrimp as they are affected by household cleaners, develop observation scale, collect and analyze data, and discuss how household products and pesticides negatively impact environment.

In this triangles learning exercise, 10th graders solve 3 extensive informal geometry problems that involve triangles. First, they sketch a triangle, selecting 3 of the sides and constructing 3 midpoints. Students then draw each of 3...

In this geometry worksheet, 10th graders complete an indirect proof and order the sides or angles of a triangle. Also, students determine if a triangle can have sides with the given lengths. The two page worksheet contains twelve...

In this math learning exercise, students examine 10 geometric shapes. Students read 10 short descriptions and place the number inside the shape that is being described. Example: I have got 2 acute angles and 2 obtuse angles.

Third graders recognize geometric shapes with acute angles, make geometric shapes with acute angles on geoboards, and draw acute angles on geopaper.

Students find the orthocenter of a triangle. In this geometry activity, students identify where the altitudes meet in a triangle. They use Cabri software to explore acute, obtuse and right triangles.

Students explore the concept of concurrent lines in triangles. In this concurrent lines in triangles lesson, students work in groups to investigate properties of concurrent lines in acute, right, and obtuse triangles. Students use a...

In thins triangles review worksheet, students examine 3 triangles and their measurements. Students classify them as acute, right, obtuse, equilateral, isosceles, or scalene.

In this angle vocabulary card instructional activity set, students identify the vocabulary associated with angles such as: ray, vertex, acute angle, segment bisector, and corresponding angles. They identify 23 terms but there are no...

Students use wax paper to look at different properties of circles such as chords, tangent lines, inscribed angles, and inscribed angles in a semi-circle, as well as finding the center of the circle, and use GSP to investigate cyclic...

In this math review worksheet, 4th graders read a graph and identify the amount of money earned during a specific week. Then they solve a word problem using multiplication or addition. Finally, students identify which angle shown is best...

Introduce young learners to the read-aloud process with a short biographical passage about Ray Charles. After listening to the passage, class members respond to factual, inferential, and evaluative questions, and then create a timeline...

Fifth graders practice the concepts related to finding and identifying different angles. There are examples included in the instructional activity that are useful for the teacher to deliver the instructional activity.

Students are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.

In this word search learning exercise, students locate 7 types of triangles. Triangles include isosceles, acute, equilateral, right, and obtuse.
