Learners investigate surveying in this secondary mathematics lesson. They will explore a real world application of geometry and trigonometry as they create a plot plan using a geometry utility and calculate the area of the land parcel.

In this DC motor instructional activity, the learner answers 3 open-ended questions pertaining to the design of a DC motor. The instructional activity is printable and the answers are revealed online.

In this tessellation worksheet, students draw tessellations using specified figures. This one page worksheet contains five multi-step problems.

Students discover that side measurement is used in determining angle classification of a triangle. By squaring sides, they predict whether triangles be right, obtuse, or acute. They prove the Pythagorean Theorem and use it to solve...

Students explore measurement in terms of pizza toppings. In this math lesson plan, students draw a circle using string and a ruler, determine areas of different size circles, find how many two topping pizzas can be made using 14...

Your learners will construct the perpendicular bisector of a chord. They use Cabri Jr. to construct a circle and a perpendicular bisector of a chord. They then measure lengths of the chords and perpendicular bisectors. Learners 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 investigate ways to save our environment by creating a recycled product.  In this sustainable materials lesson, students create a magazine holder by recycling a large cardboard box and gift wrap or wallpaper.  Students...

In this geometry worksheet students explore similar polygons and determine measure of missing sides and angles. Students use indirect measurement with similar triangles and determine the area and volume of similar figures. The seven...

Students use roadside kill to use taxidermy skills, become comfortable working with animals and dissecting.

In this constructing triangles online learning exercise, students construct thirteen triangles on paper first and then type in their answers on line. Students can check their answers as they go and the computer calculates the overall...

In this math worksheet, students will work with a coach to determine which shapes (in a box of shapes) are congruent. Students will follow a step-by-step process and notes are provided for the coach.

Students set up and conduct a scientific experiment to demonstrate data collection. In this scientific process instructional activity, students complete an activity with the specific objective of using a slingshot to fire a t-shirt into...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

In this geometry worksheet, students answer questions about midpoints, distance, lines and segments. They are given different shapes and asked to calculate the angles, and sides of polygons.

In this law of sines worksheet, high schoolers solve 9 multiple choice and short answer problems.  Students use the law of sines to missing side lengths and angles of triangles.

In this geometry activity, students solve problems based on the triangle inequality theorem(s) in which determine if the given lengths can form a triangle, given two sides of a triangle determine the range of the third side, and order...

Investigate the properties of the shape formed by connecting the midpoints of adjacent sides of a quadrilateral. In this properties of the shape formed by connecting the midpoints of adjacent sides of a quadrilateral lesson, students use...

Students excavate an artifact. In this archaeology lesson, students get a bucket filled with dirt and a broken up artifact. They work in groups to take it out and to find what its purpose was. 

Students explore intertidal zones. In this intertidal zones lesson, students work in small groups and use ready-made materials to create a model of intertidal zones. Resources are provided.

Second graders design and sketch a model house. For this technology lesson, 2nd graders construct their house using teacher provided materials. They present their finished project and explain their design in class.

Learning how to define vocabulary words related to solving parallelograms will assist your learners in identifying different parallelograms. They use the navigator to view different shapes created by moving the parallelogram around.

Is the amount of information getting overwhelming for your geometry classes? Use this strategy as a way to organize information. The resource provides a handout of information studied in relation to triangle congruence. It includes a...

This lesson requires a worksheet that is not connected. It is integral to the lesson.
