Lead the class in a Greek history lesson with a geometric twist. Pupils relate a short video about geometric properties to modern-day methods of solving for unknown angles. They discuss parallel line theorems and complete...

What's the moral of this story? Units save lives! Teach measurement conversion through storytelling in a quick math-based lesson. Young scientists learn how one country's decision to swap from imperial to metric standard units caused an...

Conduct research on the Internet about labyrinths and mazes to learn about proportions and ratios. Inquisitive minds design their own maze, one maze is chosen and proportionately enlarged to 20 feet by 30 feet. This is a fun challenge...

Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, students apply this new knowledge to...

Upper graders explore the topic of volume. For this math lesson plan, pupils count volume in cubic units, multiply to find volume, estimate volume, write a multiplication sentence to find the volume, and make a cost analysis of different...

How does your lifestyle measure up in terms of your ecological footprint? Young ecologists examine their impact on the planet using an insightful online calculator. A short quiz asks users to rank the size of their homes, their energy...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

You've investigated relationships between chords, radii, and diameters—now it's time for arcs. Learners investigate relationships between arcs and chords. Learners then prove that congruent chords have congruent arcs, congruent arcs have...

Explore lines tangent to a circle. In this math lesson, students manipulate circles and lines on a TI calculator. They draw a circle  and analyze perpendicular lines intersecting the circle in only one place. This activity works...

Computers are useful for more than just surfing the Internet. Pupils first investigate scatter plots and estimate correlation coefficients. Next, they use Microsoft Excel to create scatter plots and determine correlation...

Looking for a real-world situation to practice converting units? In this problem, learners must change miles per gallon to liters per km (or vice versa) to determine which car gets better gas miileage. It is a relatively short problem,...

Turn your classroom into a greenhouse with a lesson plan on plant growth. First, investigate the different parts of seeds, identifying the seed coat, cotyledon, and embryo. Then plant the seeds and watch them grow! Measure the new...

Here is a simple, yet clever lesson on how to teach the important concepts of greater than, less than, and equal to. Pupils write their names down on grid paper - one letter per box. They compare their names and find a name that is...

Teach statistics by analyzing raisins. A thorough activity provides lesson resources for five levels to include all grades. Younger pupils work on counting and estimation, mid-level learners build on their understanding of the measures...

A complete instructional activity on dividing whole numbers by other whole numbers and getting a fraction result. Groups of learners use fractions bars, and strips of paper that are cut to specific lengths. The hands-on activities in the...

Don't let your classes get stuck on area calculations—grab their attention with an inquiry-based lesson! Scholars must develop a plan to determine how may sticky notes it takes to cover the surface of a door. They decide on the...

Noah didn't construct this kind of arc. High school scholars first explore how angles can be formed in circles. They then learn relationships between angles and arcs by conducting an exploratory activity where they position and draw arcs...

Boat ramps move with waves and changes in water level. Scholars decide on the proper length for a ramp so the angle connecting both sides is appropriate. They visualize the situation and use a simulation to view the results with their...

Who's on second? Young mathematicians use a diagram of a baseball field to find the distance a catcher must throw to reach second base. A brief video of such a play during a baseball game sets the stage for the assignment.

First graders examine measurement. In this measurement lesson, 1st graders practice using nonstandard units to help in measuring objects. Students listen to How Big is a Foot and complete an activity using unifix cubes to measure line...

Fourth graders are introduced to the various types of measurements. Using a recipe, they practice measuring out the correct amount of ingredients while making the food. They also practice using a scale and following the directions on a...

Students work in groups to make accurate measurements. In this area and perimeter measurement instructional activity, the student groups determine what they will measure and what tools they will need, then find the accurate measurement...

Students measure and write specific metric distances. In this archaeology lesson, students are given specific artifact locations on a map and measure the distance using millimeters.

High schoolers use principles of geometry to measure the circumference of the Earth. In this applied geometry lesson, students use mathematics to determine scientific information. They make measurements, calculate the central angle,...
