An outstanding lesson plan on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Third graders discover the main purpose for totem poles was to communicate with others. In groups, they compare and contrast the four types of totem poles and the various symbols used. They write their own stories based off of pictures...

Graph A goes with equation C, but table B. The short assessment task requires class members to match graphs with their corresponding tables, equations, and verbalized rules. Pupils then provide explanations on the process they used to...

Students gain an appreciation of the polygons and polyhedrons around them that make their world one of order and strength. They build polygons and polyhedrons, and then construct airplanes out of polygons.

Tenth graders explore congruent triangles.  In this geometry lesson plan, 10th graders investigate the conditions necessary to prove two triangles congruent.  The lesson plan combines dry erase board activities and the use of...

In this geometric calculations of solar storms worksheet, students use a diagram indicating the location of 2 STEREO satellites, the earth and the sun to calculate the distance between a Coronal Mass Ejection and the Earth. They use...

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

Students work in groups to research clocks and practice telling time. In this telling time instructional activity, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles...

Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Students create a circle using the taxi-cab metric. In this geometry lesson, students identify the properties of circles. They identify the idea of geometric shapes and how they come about.

Learners find out the meaning for prefixes used in math vocabulary. By dissecting words used in everyday math, they figure out what the prefix indicates and what the word means. A variety of well-organized worksheets and activities...

Students identify the properties of solids and polygons. In this geometry lesson, students identify the different measurements of a triangle. They use congruence parts and theorem to prove their answer.

Students construct polygons. They identify attributes of three-dimensional shapes. Students name common three-dimensional shapes. They draw three-dimensional shapes, and sort three-dimensional shapes. Students use K'NEX materials sets to...

Students identify and define properties of triangles. In this geometry instructional activity, students identify the missing sides and angles of right triangles. They use the rules of the Pythagorean Theorem to solve their problems.

Second graders practice vocabulary related to measurement, mathematics, and dinosaurs. Using the engaging topic of dinosaurs, learners will calculate various information about dinosaurs and use measurement vocabulary. They will also...

Young scholars investigate the properties of two and three dimensional objects. In this geometry lesson, students differentiate polygons based on similarity and congruence. They make observation and interpret the data.

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Students design a cafeteria floor plan. In this area and perimeter lesson, groups create an efficient lunchroom layout on poster board by using geometric shapes and formulas as the basis for their designs. In the accompanying writing...

Sixth graders create polygons. For this shapes lesson, 6th graders explore prefixes such as oct, tri, quad, pent, etc. and share their findings. Students use pattern blocks to create two different polygons and label them.

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Students find triangles in the real world. In this geometry lesson, students analyze and identify properties of two and three-dimensional objects. They differentiate between similarity and congruence.

Fifth graders explore polygons. In this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

Students identify properties of circles. In this geometry instructional activity, students identify the center of two intersecting circles.They use Cabri software to create circles and move it around to make observation.
