Examine ratios and proportions in several real-world scenarios. Children will calculate unit rates, work with proportions and percentages as they plan a party, purchase produce, and take a tally. This lesson plan recommends five...

They say a picture is worth a thousand words—and your pupils may agree after this instructional activity! They read a geometric description and create a diagram from that description. Their diagrams help them find unknown measures based...

Challenge your classes to combine geometric and algebraic concepts with an activity that builds on concepts learned in the first three lessons of the series. The fourth part asks scholars to identify geometric angle relationships and use...

Learners build confidence working with geometric tools and develop their construction techniques in the sixth lesson plan of the 29-part series. Given a geometric description, they use a compass, protractor, or ruler to create it....

Connect the size of a rolling cup to the size of circle it makes. Pupils view videos of cups of different sizes rolling in a circle. Using the videos and additional data, they attempt to determine a relationship between cup...

Discover the connection between calories and weight. Pupils multiply their body weight times calorie estimates for various physical activities to calculate calories burned per minute and per hour. Worksheets a well as website links are...

Pupils develop a definition of a circle based upon its radius in the 17th segment of a 28-part series. They determine the relationship between the radius and the diameter of a circle. To round out the lesson plan, they use the formula...

The third activity in the series of 29 asks learners to identify types of angles to verify angle relationships. They find unknown measures using vertical, adjacent, complementary, supplementary, and 360-degree angles.

The battle of the sexes? Scholars first examine data on hurricane-related deaths and create graphical displays. They then use the data and displays to consider whether hurricanes with female names result in more deaths than hurricanes...

High schoolers find the volume of pyramids and cones. In this volume of pyramids and cones lesson, learners explore the relationship between the volumes of prisms and pyramids. They investigate the relationship between pyramids and cones.

Ddefine the relationships between fractions, decimals, and percentages in a series of lessons. The class practices converting between these three versions of a number. They also find the common factor of a numerator and denominator and...

Fifth graders complete measurement problems where they use powers of ten, read metric measurement tools, estimate measurements, and more. In this measurement lesson plan, 5th graders complete 10 problems.

Fourth graders explore perimeters. In this measurement lesson, 4th graders examine example problems that highlight how to calculate the perimeters of rectangles in inches and centimeters. Students also practice solving problems that...

Young scholars explore geometry by using computer applications. In this spatial measurement lesson, students discuss the difference between area, weight, volume and other forms of measurement. Young scholars utilize computer applications...

Students explore geometry by conducting a science experiment. In this circumference measurement lesson, students review the Greek geographer Eratosthenes who first discovered the circumference of our planet. Students utilize...

Students practice math. In this measurement activity, students measure their favorite candy bars to the nearest inch. They work independently to compare the different lengths of the candy bars they measure.

Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

Middle schoolers explore angle measure as they estimate angle measure and measure and draw angles of less than 360 degrees. The lesson emphasizes the use of estimation when measuring angles.

Students recognize that measuring tools can come in many different shapes and sizes. In this early childhood math lesson plan, students develop creative-thinking, math, and social skills as they use nontraditional measuring tools.

Young mathematicians identify central angles, arcs and radius of circles in this pre-calculus lesson. They identify the proportion of the circle based on its radius while they convert between degrees and radians measurements.

High schoolers explore quadrilaterals in this geometry lesson. They will draw a quadrilateral, measure the angles, and find the sum of the measures of the interior angles using Cabri Jr. The interactive capabilities of Cabri Jr. allow...

Students investigate shapes and sizes by creating a riddle.  In this geometry lesson, students read one of two books and investigate facts about an object's size.  Students write a riddle using the facts they have read and cut...

Learners relate math to real life scenarios. In this geometry lesson, students launch a ball tracking each launch using a graph. They analyze their data for speed, angles and distance, trying to improve on each launch.

High schoolers investigate the sum of the measures of the angles of a triangle. They draw a triangle and measure the interior angles. Using Cabri Jr., learners find the sum of the measures of the interior angles. The lesson provides an...
