Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Your learners collaboratively find the lines of symmetry in an equilateral triangle using rigid transformations and symmetry. Through congruence proofs they show that they understand congruence in terms of rigid motions as they...

See how art can communicate the idea of working together with your class. They will view art and describe space, color, shape, and lines in art. Then they will overlap in their art to show a sense of space. In the end, they will be able...

Challenge: create an assessment that features higher level thinking from beginning to end. A ready-made test assesses knowledge of dilations using performance tasks. Every question requires a developed written response. 

A diameter is the longest chord possible, but that's not the only relationship between chords and diameters! Young geometry pupils construct perpendicular bisectors of chords to develop a conjecture about the relationships between chords...

In this health worksheet, students examine the human body and make mental connections to the target function highlighted in the sheet.

Eighth grades can master the ELA Common Core standards! Show your learners the connection between classroom activities and assignments and the standards with this set of "I Can" statement posters. Each standard has been rewritten as an...

Graph A goes with equation C, but table B. The short assessment task requires class members to match graphs with their corresponding tables, equations, and verbalized rules. Pupils then provide explanations on the process they used to...

Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the lesson. Copious, comprehensive...

Students research, brainstorm and analyze the events that lead up to the Revolutionary War. They critique a piece of artwork depicting a scene from the Revolutionary War. Each major battle is plotted on a map to show a visual...

Celebrate Opposite Day by using a Visual Thesaurus to match words to their antonyms. They match a list of vocabulary words to their antonym counterparts using the Visual Thesaurus, and then they play Antonym Bingo with the words from...

What information can be gleaned from a box and whiskers plot? Discuss the five summary values - minimum, maximum, upper and lower quartiles, and median - and what conclusions can be made from these values? Included here is a matching...

The Common Core is intended to help all children meet high academic standards. Here is a Common Core designed lesson that is intended for learners with communication or language difficulties. The lesson is written in a narrative style...

Whether or not you are new to using The Odyssey with your classes, this publisher-produced teaching guide deserves a place in your curriculum library. The packet includes background information, chapter by-chapter summaries, study...

Self reflection is an important skill to reinforce in our children, and it's especially helpful to help them realize who they are in the context of their environment. A collection of lessons about self image and community encourage...

Fourth graders discuss the various attributes of quadrilaterals. In groups, they use the attributes to sort quadrilaterals into different classes and a hierarchy. They review the new vocabulary and attributes with a partner to end the...

Students differentiate between parallel and perpendicular lines. In this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

Students study the layer of the atmosphere. In this lesson on the atmosphere, students discuss the composition of the air around us and how the atmosphere was formed. Students create a scale model of the layers of the atmosphere.

Young scholars build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.

Geometers explore symmetries of isosceles triangles by using rigid transformations of the plane. They complete four tasks, including congruence proofs, which illustrate the relationship between congruence and rigid transformations. The...

Students view a video to discover how patterns in nature relate to math. They explore the concept of exponential growth by observing and creating fractals. They solve and design word problems.

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Students, through various activities, explore online databases. Using the internet, students explore the distributors websites. They collect specific information on selected products. An spreadsheet with price comparisons is developed....
