Young scholars explore the origin of tangram. In this algebra lesson, students form different shapes and figures using tangram. They solve for the area of different shapes without using any geometric formulas, but the idea of tangram...

In this fractions and patterns activity, students make patterns of parallelograms and trapezoids using pattern blocks. Students complete 6 problems.

Fifth graders study perimeter. For this math lesson, 5th graders use Cheerios to find the perimeter of various polygons. Students discuss how to figure the perimeter of triangles, squares and rectangles.

Fifth graders look at the Garrison flag and estimate how big it is. In this measurement lesson plan, 5th graders then calculate the area and perimeter of the flag.

In this determinant worksheet, students explore determinants, area and volume. This two-page worksheet contains explanations and examples. It provides two problems for students to solve.

In this math worksheet, students define the sets of vectors. They also observe the concept of area for the parallelogram and how vectors are used.

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

Investigate vectors in standard positions and use the CellSheet application on the TI calculator to find the sum of two vectors. Convert from polar to rectangular coordinates and vice versa, and show graphs of the vectors.

Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...
