First graders access prior knowledge about pumpkins and read the story Pumpkin, Pumpkin. They will sequence the life cycle of the pumpkin through the use of picture cards and then sing a song about the life cycle of the pumpkin and plant...

Take young geologists on an exploration of the collection of rocks and minerals that we call Earth with an upper-elementary science lesson. Through a series of class discussion and hands-on investigations, students learn about the...

After completing a task involving examining the ratio of areas of triangles and circles in a given figure, scholars examine sample responses to identify other strategies they could use to solve the problem.

Do your learners always, sometimes, or never remember the properties of the segments in triangles? Get that number closer to always with a creative lesson analyzing all four segments. Scholars consider a statement about one of the...

From the apple on your desk and the coffee cup in your hand, to the cabinets along the classroom wall, basic three-dimensional shapes are found everywhere in the world around us. Introduce young mathematicians to the these common figures...

High schoolers explore the concept of circles as they construct a circle using a program such as Cabri Jr. Learners construct a chord and a diameter that are perpendicular, then measure the bisected chord and notice that both sides of...

In this length activity, students read about the properties of carbon. Students also decide which of the given phrases go with which compound.

It's all about lines when going around. Pupils graph the relationship between the length of a side of a square and its perimeter. Class members explain the origin in context of the side length and perimeter. They compare the graph to the...

What kinds of cups can bend? Kindergartners find out with a straightforward science inquiry, designed to teach them about the properties of materials. They hypothesize about the flexibility of a china cup, a plastic cup, and a paper cup....

How does sound travel in space? Fifth graders investigate this question with a science activity, in which they research the properties of sound. Schedule a lab visit for individual Internet research, or include the activity after you...

Don't shine like a diamond, refract light like a diamond. Young scientists use an acrylic block and a laser light to observe refraction. Advanced scholars figure the sine of the angles of reflection and incidence as well as mastering...

Sometimes the best things are already done for you! Here is a six-problem quiz that has a variety of problems ranging from solving quadratic equations to interpreting a function. The piece-de-resistance is the worked out answer key in...

Students understand where the number for pi comes from. They understand and use the formula for circumference. Students measure the circles given out and the diameters of those circles and record the results on their worksheet.

In this multi-faceted introduction to pi, participants perform a bevy of pi-related activities. Ranging from measuring household items to singing pi songs and reading pi stories, this fun and non-intimidating resource serves to bring up...

A neat and organized formula handout makes the circle go round, doesn't it? Full of higher algebra topics, formulas and rules, graphs and definitions—there is a way to support everyone in Algebra II or Pre-Calculus. 

Young scholars investigate the properties of circles. For this geometry lesson, students calculate the area and perimeter of a triangle. They identify the perimeter and radius length of a circle.

This lesson plan is an investigation of soil properties, particularly texture, color and space for air and water. Student inspect soil samples found in their locale, perform several tests to determine different properties, and involves a...

Define plane shapes by their properties, then use this game to reinforce those skills. Learners use given properties as clues to determine each shape. They work to name ten different shapes, six of which are polygons.

Investigate relationships between angles, arcs, and segments in circles. Pupils use geometry software to discover the relationships between angles, arcs, and segments associated with circles. Class members use similar triangles to...

Students use wax paper to look at different properties of circles such as chords, tangent lines, inscribed angles, and inscribed angles in a semi-circle, as well as finding the center of the circle, and use GSP to investigate cyclic...

Students identify properties of trapezoids. In this geometry lesson, students are put into groups and use computer programs to analyze polygons. They drag and move the shapes around as they make predictions.

There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

Teach how to differentiate between chords and perpendicular bisectors. In this geometry instructional activity, students relate the properties of chords and circle to solving right triangle. They define what makes two chords congruent in...

In this algebra worksheet, students graph exponential equations and use the formula to translate the graph on a coordinate plane. There are 3 word problems.
