Explore the world of shapes! After free tangram exploration and pair share time, learners describe various patterns and shapes in both the natural and designed world. They investigate the use of tangrams to create patterns and shapes.

Intelligent? Arrogant? Obnoxious? After completing Chapter 18 of Freak the Mighty, individuals fill out a semantic feature chart for characters in Rodman Philbrick's novel. Group members then use their charts to discuss relationships...

Measure a tree? Yes, measure a tree! Students get outside and measure a tree's trunk, crown, and height. Each group compares their answers to determine if any re-measuring is necessary. Once back in the classroom, students make bar...

First graders complete a variety of experiments with solids, liquids and gases. They read books about matter, identify the characteristics of solids, liquids and gases and the sort and classify a variety of matter. Students make...

Students identify the concepts of density, mass, and volume that define the property of a substance. They also determine that the properties of materials, such as, density and volume, can be compared and measured by using rulers,...

Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...

Middle schoolers build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...

Students demonstrate the process of creating a scaled rubber band enlargement of a simple drawing. They observe and discuss a teacher-led demonstration, and create a scaled rubber band enlargement of simple drawings and their invention...

Here is a quick 15 minute lesson intended to introduce subtraction. Learners count and subtract gummy bears to complete 5 problems. The lessons suggest that the gummy bears can be saved and used the next day, but gummy bears get gross...

Linear, square, and cubic units are all investigated as different types of packages are measured. The teacher will need supplies such as a box of aluminum foil, a package of ribbon, and a bag of mulch. The class determines the...

Eighth graders explain the relationship between the position of the sun, a city's latitude and shadow length. Ratio's, geometry, and algebra are used to determine the shadow lengths and building heights. A sun angle (altitude) charts to...

Second graders review measurements in inches and practice measuring different objects. As a class, they estimate various objects in their classroom and compare their estimation to the actual measurement. To end the lesson, they complete...

First graders explore geometry by completing a worksheet in class. In this non-standard measurement unit lesson, 1st graders discuss different techniques for measuring items without the use of a ruler. Students read several short stories...

Eighth graders make inquiry about the existence of matter. A definition of the word is needed before students can engage in various activities. The application of knowing about matter is done in the working of experiments.

Third graders use an online database to gather information about five dinosaurs that are of interest to them. Using a chart, they record their length, height and two interesting facts for each dinosaur. They draw a picture of the...

Students review what a cylinder is and how a cylinder is measured. They build a variety of cylinders with different heights and radii. They compare the surface area and volume of each cylinder and discuss anything that surprises them...

High schoolers differentiate between similarity and congruence using polygons. In this geometry lesson, students label triangles based on their properties. They find missing sides and angles using the interior sum theorem.

Fourth graders practice measuring different objects in inches. Individually, they estimate the length of the same object in centimeters and then calculate the actual length. They compare and contrast their estimate to the actual length...

Eighth graders measure height and shadow length of other students on a sunny day and develop a ratio. They apply the ratio to other students and objects using shadows to determine height.

Students examine the elevation of the sun to discover the changes in seasons. They observe and measure the length of their shadow. They compare this measurement to one taken four months later.

Student measure the length of the sides of rectangles and squares using inches, feet and yards. They determine perimeters of rectangles and squares. They then determine areas of rectangles and squares. Student compare measurement of...

Students will measure common everyday objects in order to calculate pi. In this measurement lesson plan, students measure the circumference and diameters of objects and fill them into a chart which helps them calculate pi.

First graders observe and measure their shadows. They go outside at three hour increments during the course of a day. Each time students measure and record the length of their shadows. Students read books about shadows and discuss why...

Students order their classmates from smallest to largest foot length.  In this ordering their classmates from smallest to largest foot length lesson, students trace each of their classmates foot.  Students read a story called,...
