What can jump 150 times its own length? Fleas! Assign this reading passage to your class, and they'll not only develop reading skills, but they'll learn about fleas. After reading the excerpt, they answer the questions that follow. All...

Would you use a ruler to measure the length of a soccer field? No way! Pupils explore four tools of the trade: yardstick, measuring wheel, tape measure, and ruler. They label 12 measuring tasks with the most appropriate...

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

What to wear today; such a vexing question. Spend some time introducing the names, fabrics, types, colors, and functions of various articles of clothing to your class. Each child will take turns asking each other what they are wearing....

Have you ever wondered how many ants make up an elephant? Inquisitive minds will be amazed as they use scientific notation to compute and compare the mass of an elephant to an ant. Have participants make guesses and see how close they...

After reviewing characteristics of seven types of triangles, young geometers discover how to find the missing angle of a triangle. Then, they practice identifying triangles, find missing angles, and find missing side lengths of...

Use patterns to your advantage! The Pythagorean Theorem allows learners to find missing sides of right triangles. Problems include those with both rational and irrational lengths. 

Don't be a square! Young mathematicians determine the slope and length of a line segment. They then prove whether four given coordinate points form a square.

The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value...

Designers in Prague are not diagonally challenged. The mini-assessment provides a complex pattern made from blocks. Individuals use the pattern to find the area and perimeter of the design. To find the perimeter, they use the Pythagorean...

Determine the number of possible genetic codes. Class members are challenged to determine the number of possibilities of a genetic code that is 20 bases long. They continue to explore the average lengths of broken RNA molecules.

Begin seeing the world through the lens of geometry! Use the 19th installment in a 25-part module to apply the Pythagorean Theorem to solve real-world problems. Individuals sketch situations resulting in right triangles such as the...

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

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...

Class members investigate rectangles on the coordinate plane. They determine the length of line segments in the coordinate plane with the same x-coordinate or same y-coordinate and then solve geometric problems involving perimeter...

Model geometric concepts through a hands-on approach. Learners apply similar triangle relationships to solve for an unknown side length. Before they find the solution, they describe the transformation to help identify corresponding sides.

And round and round the park we go! Given a description of an amusement park with the locations of three attractions connected by walkways, learners consider what happens when additional attractions join the mix by doubling the length of...

Is the gestation length of an animal a predictor of the average life expectancy of that animal? Learners analyze similar data for more than 50 different animals. They choose a data display and draw conclusions from their graphs.

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become familiar with the...

In this science worksheet, students identify and explain what each unit represents and how much each one equals. Then they use a metric ruler to locate each measurement and write it on the line. Students also locate the distance between...

In this math instructional activity, students are shown a variety of objects such as a bridge, a chair, a couch, and etc... Students are asked to look at the objects and determine which is the longest, narrowest, shortest, and etc...

Give pupils a ruler and this instructional activity so that they can practice measuring down to the quarter inch! Drawings of six various objects are depicted for them to apply their measurement skills to. The assignment concludes with...

In this volume problem instructional activity, students determine the volume of various objects. They compare similar objects and determine the percent of increase and decrease of the surface area and volume. This one-page instructional...
