Young scholars explore counting, sorting, and graphing skills. In this data analysis lesson, students sort jelly beans by color, count the jelly beans, and create a bar graph of the jelly beans according to color.

Seventh graders investigate a ratio found in nature and in numerous pieces of artwork throughout history. The instructional activity is cross-curricular and builds a sense of appreciation of design for students.

Students create a ruler for the purpose of measurement using the standard and metric systems. The rulers are of different lengths and are compared to one another. Then students make conversions of different lengths using both systems of...

Eighth graders participate in an experiment that emulates a sonar signal bouncing off the ocean floor. They determine how the ocean floor is measured by the length of time it takes for the sonar signal to return. They work with a wooden...

Second graders learn about plant systems and how plants grow and function. In this plant lesson plan, 2nd graders collect data based on roots, leaves, terrariums, plant uses, and locations of certain kinds of plants. They fill out...

Pupils investigate similar triangles and proportions as they make conjectures about the length of sides of similar triangles. For this lesson, have your class construct similar triangles using Cabri Jr so that they share a common vertex.

Students make origami frogs to race. After the race they measure the distance raced, collect the data, enter it into a chart. They then find the mean, median, and mode of the data. Next, students enter this data into Excel at which time...

Students create an airplane by listening to directions. They also to measure the pieces for the airplane and compare and contrast their test flights.

Fifth graders study environmental changes by examining the annual rings of a cross-section of a tree trunk. They access websites to complete a worksheet on the parts of a tree. They count the annual rings on a tree slice while observing...

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Students complete a unit with cross-curricular activities to learn about a healthy body and maintaining their health. In this health lesson, students complete 8 lessons to learn about good health, a healthy diet, healthy foods, healthy...

Students participate in a Mini-Olympics with measurements. In this measurement lesson, students throw items and predict how far they will go. They measure the actual distance and find the difference between that and their estimate. 

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

Math vocabulary has never been easier to understand! Use vocabulary cards to bring word walls to your classroom, helping kids make the connection between important math terms and easy-to-understand illustrations.

How do dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...

Clarify key math vocabulary terms with this series of printable cards. Three different versions of each term are provided; one with only the word, one with the word and a picture, and one with the word, a picture, and a definition. Note...

Students properly leap and measure their distance. In this leaping lesson plan, students practice leaping for accuracy and proper form. Students estimate their leaps and measure with rulers. Students determine distance covered by the...

Properties about triangles are explored in this instructional activity. Geometers make conjectures about the length of a triangle's sides, the length of the angles in relation to the length of the sides, and the measure of the exterior...

Students discover the Pythagorean Theorem.  In this discovering the Pythagorean Theorem lesson, students measure the lengths of various triangles to the nearest centimeter. Students record their measurements in a table. ...

Third graders explore vocabulary associated with three dimensional figures.  In this transformations instructional activity, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with...

Sixth graders calculate perimeter of rectangles with different dimensions.  In this perimeter lesson, 6th graders define length, width and perimeter.  Students complete a perimeter activity using a web tool to change the...

Students explore proportional reasoning.  For this middle school mathematics lesson students investigate scale drawings as they create a proportional representation for the carvings on Mt. Rushmore.

High Schoolers investigate the perpendicular bisector of a line segment. They use Cabri Jr. to construct the perpendicular bisector of a segment. The dynamics capabilities of Cabri Jr. allow your learners to observe the lengths of the...

Students create a sundial and track the movement of the sun throughout the day. Modifications to the lesson are provided for both lower and upper elementary students.
