What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

Student statisticians calculate ratios to determine how many shades of green were mixed by Ms. Baca's art class. They graph the number of blue parts against the number of yellow parts for each combination and discover that some produce...

For this dilations and similarity worksheet, pupils solve 10 different problems that include various dilations. First, they determine the scale factor of dilations found in the illustrated graphs. Then, everyone determines the...

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

Students examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...

Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...

Students solve problems involving transformations of geometric figures. They review graphing points in the coordinate plain, plot points and connect to create a triangle. Then, they reflect triangles over the x and y axis and use...

Students explore transformations. In this math lesson, students plot points on a coordinate grid and construct shapes. Students discuss movements on the grid as flips, turns and slides.

Students identify the types and characteristics of geometric figures. In this lighthouse geometric lesson plan, students review shapes that represent plane or solid.  They select items that could be used to construct a lighthouse...

Twelfth graders solve problems involving linear and angular speed. Using information about a compact disc, they solve the problem using multiple rates and conversion factors. Students also solve additional problems involving bicycle...

First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

Third graders explore vocabulary associated with three dimensional figures.  In this transformations instructional activity, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with...

Shape shifters recognize characteristics of polygons. Embracing language arts skills in addition to math, they use a thesaurus to pinpoint specific attributes of a set of polygons. They also participate in a 21-question guessing game...

A very basic presentation on the vocabulary associated with circles has come around. Math whizzes see definitions and examples of the radius, diameter, chord, and central angle of a circle. The last slide says "practice time," but there...

Learners construct a variety of right triangles using a right-angled set square, cutting corners from pieces of paper or cardboard, and using dynamic geometry software. They measure the sides of these various right triangles and record...

Solve story problems using fractions or decimals. Then, determine the reasonableness of answers using estimation.The detailed lesson plan includes essential questions, vocabulary, a materials list, and links to related units.

Examine a coordinated geometry grid to decode the hidden message. Pupils write a coded message to their parents using letter coordinates from the grid.

Graph transformations, write rules to describe transformations, find coordinates of vertices after given transformations: geometers practice these skills on a two-page worksheet in 14 problems. No answers are provided.

Fifth graders work with polygons.

Second graders identify shapes and measurements in everyday life.  In this measurement lesson, 2nd graders locate rectangles in their classroom and use standard and nonstandard forms to measure them.  Students view a video clip...

In this 6th grade math instructional activity, 6th graders solve 25 multiple choice questions.  Students determine coordinate of figures, use units of measure, expand exponents, etc.

For this slopes of lines worksheet, 10th graders solve and graph 10 different problems. First, they determine the slope of each line named in the figure and any line parallel to line b and perpendicular to line d. Then, students graph...

In this shape identification worksheet, students mark the correct answer to each of 4 multiple choice questions while working on-line. They choose from 4 choices as they identify a square, triangle, circle, and rectangle. They print the...

In this number puzzle worksheet, 5th graders use multiplication and division to fill in the missing numbers. They examine a key and fill in the shapes with the numbers that make each puzzle true.
