Fifth graders view prints of M.C. Escher's work. They look at examples of geometric figures and polygons and discuss places they have seen them. Students create their own tessellations. They write a report about the process they used in...

Learners use the CABRI application for their graphing calculator to rotate, translate, and reflect triangles. They use graphing calculators and follow detailed directions to manipulate triangles in specified ways. There are three...

For this math worksheet, students apply their knowledge of angles and rotation to solve a word problem involving an old pocket watch.  They discuss gears, rotation and accuracy.

Students investigate the reason for seasons on Earth during three activities. They construct a model of the Earth and Sun to identify patterns in the changes of the angle of light on the Earth's surface. Then they conduct a heat...

Reflected waves of light move within a plane, and because of this, polarizing materials can reduce the glare our eyes see. This resource explains how to set up a demonstration of this effect. Consider it for use in your physical science...

In this math worksheet, learners answer 3 questions about an equilateral triangle. Students then answer 3 questions about isosceles triangles. Learners then calculate missing angles on isosceles triangles.

Second graders explore the features of triangles and quadrilaterals. In this lesson on triangles and quadrilaterals, 2nd graders rotate with their group to five different activities all exploring a different aspect of geometry.

Students define properties of rectangular prisms. In this geometry lesson, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.

Learners explore the properties of rectangular prisms. For this geometry lesson, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.

Young scholars explain that many different cultures across the world developed their own reasoning for the weather around them. They explore the different cultural beliefs of the sun's cycle and to create their own story of the sun's...

Students scan a drawing and practice a blow-up procedure. They create a third generation from a second. Students are given a new point of view in handling a human figure in the drawing.

Combine transformations and triangle congruence in a single lesson. Scholars learn to view congruent triangles as a rigid transformation. Using triangle congruence criteria, learners identify congruent triangles and the rigid...

Complex numbers were first represented on the complex plane, now they are being represented using sine and cosine. Introduce the class to the polar form of a complex number with the 13th part of a 32-part series that defines the...

Students understand that the rotation of the Earth is responsible for the seasons. In this seasonal cycles lesson, students learn how the rotation of the Earth affects the seasons. Students answer questions about the rotation, the...

In this math worksheet, students will work independently to trace a stencil on an x-axis. Then students will follow a procedure to trace the image on the horizontal line of reflection. Students will observe that reflections and rotations...

Middle schoolers study the three types of mass media messages: visual media, written media, and audio media. After a class discussion which has them list examples of each, learners get into pairs and work on analyzing the "Four A's" in...

Young scientists use a globe and a light to simulate the rotation of the earth and sun to show the seasons. Additionally, they simulate direct sunlight and indirect sunlight showing intensity of the sun, and answer questions based...

Sixth graders conduct and analyze a survey that explores public perceptions about the reasons for seasonal change. They measure the changing length of days, observe shadows and discuss how the Earth's axis of rotation affects the seasons.

Time to learn about sundials. Scholars see how to build sundials after learning about Earth's rotation and its relation to time. The unit describes several different types of possible sundials, so choose the one that fits your needs — or...

Students compare graphs of their data that was generated on a NASA website.  In this seasons lesson students complete a lab activity. 

Pupils utilize The Nature Park Adventure educational software program to Introduce Modelling, Including the Estimation of Angles.

Proving triangles are similar is often an exercise in applying one of the many theorems young geometers memorize, like the AA similarity criteria. But proving that the criteria themselves are valid from basic principles is a great...

Students discuss that the conservatin of energy states that the energy imput must equal the energy output. They then figure out how can a machine help you to perform task otherwise considered impossible? Students discuss the six simple...

Why are there so many different types of triangles? Be that as it may, beginning geometers need to understand the differences between equilateral, isosceles, scalene, and right triangles, and they get a visual approach with this...
