Investigate the area and perimeter of polygons in this geometry lesson plan. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape...

Here is a real-life lesson plan! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

Review and use standard units of measure with your math class. They move from station to station estimating and measuring length, volume, weight, and area. At each station they estimate and measure, and then compute the difference...

Young scholars design their own playground equipment. In this design instructional activity, students take pictures of equipment they like and make a class pictograph of their favorite ones. They investigate the design, research...

Measure your pupil's learning in a lesson designed to explore decimals by weighing different candies on a scale and recording the weight. Small groups then compare and order the decimal weights on a number line to show their...

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Get three planes to line up safely. Individuals work through a set of problems to eliminate spacing conflicts between three airplanes in flight. The pupils use their knowledge to change the airplanes' speed or route to meet a...

Part lesson, part worksheet, this handout walks math minors through the comparison of two decimal numbers. It teaches them the trick of tagging zeroes in to get the numbers to be the same length to better understand place value. A set of...

Practice subtracting decimals to the hundredths place. This assignment includes amounts of money and units of measurement. Three sections of problems provide subtraction problems in both vertical and horizontal formats, as well as two...

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this instructional activity to...

Fourth and fifth graders make a protractor and identify various angle types. In this protractor and angle lesson, learners make their own protractor and use it to measure a variety of angles. They complete worksheets while identifying...

How are skyscrapers built? What does it take to make a structurally sound building? How can one work within a budget to complete a building project? These guiding questions will be investigated and answered within a hands-on...

It's time to roll up those sleeves and get a little dirty in the second lesson plan of this series on the science of food. Investigate where plants and animals get the minerals they need to live in this two-part exploration of soil....

Pattern blocks and shapes demonstrate how to add and subtract fractions. By aligning blocks with different shapes, learners figure out how to create a whole, and then how to add and delete parts from that whole.

Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

Patterns emerge as the class works together to fill in a number grid. This whole group activity is designed to make all learners feel successful, and ultimately turns into a lesson on the least common multiple.

Strengthen young geometric muscles with this exercise in finding surface area and volume. Six problems provide practice at determining the surface area and volume of two solid figures shown in cubic units, deciding which to find given a...

Nothing says organization quite like a table. The third lesson plan in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...

Harness the power of bacteria. Scholars see how using organisms that exist in nature can help solve human problems in the process known as bioremediation. They research and discuss several successful examples, such as using oil-eating...

Students explore weather instruments. In this weather lesson, students make rain gauges, anemometers, and barometers following the instructions given in the lesson. Students set up a weather station using their instruments and record and...
