Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.

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.

Learners inspect the causes and effects of earthquakes and examine how seismic waves travel. In this earthquake lesson, students determine where earthquakes happen and why, before determining how to build an earthquake resistant...

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.

Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.

Students examine the effects on motor functions in mice. They make observations and graph their data. They analyze the data and draw conclusions in each of the three experiments.

In this end of the year math test worksheet, 4th graders complete problems including addition, division, measurement, decimals, and more. Students complete 22 problems. 

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 construct three-dimensional models of the three pyramids at Giza. They research the building of the pyramids and record the height, base and angle measurements of each pyramid. They create a file of facts regarding the pyramids.

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.

Student form and test hyptheses using indirect and direct observation. They launch marbles to determine the shape of a hidden object.

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...

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...

In this AC phase worksheet, students answer 24 questions about AC and DC voltages, phasor diagrams, sine wave graphs and Lissajous figures.

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 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...
