Third graders review the scientific method and how and in which steps scientists use observations and measurements. Then as a class, they hypothesize which ramp will send the car the farthest. They break into groups and send cars down a...

Third graders review angle criteria and then stand. They demonstrate with their hands each type of angle called out by the teacher: right, acute, or obtuse. Music is added and students follow teacher in an angle aerobics class peppered...

Students identify the properties of a circle. In this geometry lesson, students relate properties of diameter to sections of a pizza. They calculate the measure of an arc and missing angles.

In this geometry activity, students use a ruler and a protractor to measure the lengths of the line segments and size of the angles that make up a drawing of a Christmas tree.  The one page activity has one problem.  Answers...

In this construction geometric shapes worksheet, student use the software program for instruction then construction shapes and bisect angles for four questions.

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Pie isn't just for eating! Scholars learn to create pie charts and circle graphs to represent data. Given raw data, learners determine the percent of the whole for each category and then figure out the degree of the circle that percent...

Take a coordinated look at rectangles. The task asks pupils to plot the length and width of created triangles in the coordinate plane. Using their plots, scholars respond to questions about rectangles and their associated points on the...

Presenting ... the gold standard for a lesson. Learners first investigate a task maximizing the area of a plot for gold prospecting. They then examine a set of sample student responses to evaluate their strengths and weaknesses.

Students study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.

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...

High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...

Students discover the Pythagorean Theorem.  In this discovering the Pythagorean Theorem lesson, students measure the lengths of various triangles to the nearest centimeter. Students record their measurements in a table. ...

Learners draw triangles on their graphing calculators using the Cabri Junior application. In this graphing calculator lesson, students follow step by step directions to create triangles on their calculator. They identify the type of...

Students engage in a lesson that is concerned with the concept of quadrilaterals and how they are used to create a rectangle for a door. They create a drawing of a quadrilateral while finding the sum of the angles. They practice problems...

Learners build polygons on their geoboards. In this geometry lesson plan, students build and then draw it on paper and label it. Learners then switch with a partner to try an make a symmetrical shape.

Students blow bubbles using various wands and observe the shape of the bubble. They design and construct new wands and then measure and illustrate the bubbles.

Your task today: count all the trees on a tree farm. To complete the assignment, learners first estimate the number of trees on a tree farm using random sampling. To improve their own response they then evaluate provided...

In this math worksheet, learners draw quadrilaterals and also find the sums of the inner angles for each. They practice drawing rhombuses as unique quadrilaterals.

Tenth graders investigate geometric construction.  In this geometry lesson, 10th graders explore the procedure for copying an angle and a segment.  The lesson emphasizes the difference between a sketch, a drawing, and a...

Learners identify the ratios of trig identities. In this geometry lesson, students solve the missing sides and angles of triangles using trig ratios. They relate the graphs and waves to real life scenarios.

In this congruent triangles worksheet, 10th graders solve 6 various forms of problems that include a proof and a word problem. First, they draw and label triangles and indicate the additional pairs of corresponding parts that would have...
