Perimeter check! Pairs work on finding the areas of semicircles and quarter circles using a relationship with squares. The problems challenge pupils to find areas of composite figures made from rectangles, semicircles, and quarter circles.

In this circle worksheet, students solve problems involving the circumference, area and arc length in a circle. They explore the union of circles and semicircles, as well as the line segments tangent to the circle. This two-page...

Students identify different parts and properties of circles. In this geometry lesson, students identify the radius, diameter, semicircle and inscribed angle of a circle. They identify the tangent lines to a circle.

Learners construct a variety of right triangles using a right-angled set square, cutting corners from pieces of paper or cardboard, and using dynamic geometry software. They measure the sides of these various right triangles and record...

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

How do you find arc lengths and areas of sectors of circles? Young mathematicians investigate the relationship between the radius, central angle, and length of intercepted arc. They then learn how to determine the area of sectors of...

Students make several models of the solar system to learn the positions of the planets in the solar system as well as relative distances and sizes. Creation of these models will help them identify the planets by size, shape, color,...

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this lesson. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is by viewing a...

Students read The Hungry Caterpillar to examine healthy eating habits. In this food and nutrition lesson, students role play the various responsibilities during family mealtime. They will discuss the struggles of healthy eating, and the...

Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.

Make origami ducks with your class to reinforce geometry concepts and vocabulary; develop fine motor and visual translation skills; and enrich study of Japanese culture, the pond habitat, or migration. Create a whole group "worksheet"...

This is the first lesson out of nine in this golf unit. So, let's start at the beginning. A little history, some rules, and an introduction to golf terms. Practice the full golf swing without a club in hand. Focus on stance and posture....

Conduct a Reader's Theater. Third, fourth, and fifth graders rewrite books with a baseball theme to a Reader's Theater format. They form groups of four or five, practice reading the script, and then perform it for an audience.

The class will examine a series of live or stuffed animals in order to learn how different animals survive in distinctive habitats. As they examine each animal, they will be asked a series of critical thinking questions geared at getting...

In this geometry worksheet, 10th graders calculate the perimeter and area using the specific formula for that polygon. There are 5 questions with an answer key.

Students examine public opinion about the war in Iraq. They read and discuss an article, participate in a poll, analyze statistics, create annotated scales demonstrating their findings, and write a reaction paper.

Students examine the signs associated with a childs readiness to start solid foods.  In this infant development lesson students understand the signs of hunger in infants.

Students read Lilly's Purple Plastic Purse by Kevin Henkes. They complete a variety of cross-curricular activities surrounding events of the story. Included are reading, art, math, science, writing, social studies, and library connections.

Students follow the directions on the attached worksheet to construct shapes using Geometer's Sketchpad. To start the lesson, it is suggested that the teacher guide the students through the initial problem. When constructions are...

Twelfth graders build a model of the following figures with the base from column I and the cross-section from column II. Draw the base with labeled axes on the graph paper and construct the figure on top of the base with the play dough...

First graders identify different kinds of lines found in common shapes. They discover ways in which an artist utilizes lines in a painting.

Young scholars manipulate and observe a 3-D model which simulates the activity of the Sun, Earth and Moon during a solar eclipse.

Tenth graders apply their knowledge of angles related to a circle, radii, secants, tangents and chords of a circle. They practice using formulas related to a circle. They also apply what has been practiced to real life situations.
