Try your hand at scale models. Scholars create a scale model of an object using a scale factor of their choice. As part of the project, they give presentations on their processes and calculations. This is the last installment of the...

Here's a clever math worksheet that has learners measure their hand span, foot length, come up with a ration, then use that information to figure out the hand span, and foot length of basketball giant Shaquille O'Neal. A good activity!

Using a game format, learners engage in an activity called Deal or No Deal. Taking real life scenarios involving items for sale, such as cereal boxes three for $5.00, they determine whether an example is a deal or not. This lesson...

Given a box of certain dimensions, young mathematicians must determine if a box that is twice as big, actually holds twice as much. This is a brain-teaser of a problem. The worksheet provides a handy table that has learners calculate the...

Young geometers explore relationships between units of measure and objects. Three activities provide varied opportunities to practice. Learners calculate the volume of two cylinders made by rolling a piece of paper vertically and...

It is plane to see that simple machines help reduce the force needed to perform a task.  This resource introduces three of the simple machines--the inclined plane, the wedge, and the screw, and  the formulas in order to be able...

Young scholars engage in an activity which demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by...

Young mathematicians work to recognize the relationship between their scale models of the Joides research vessel and the real vessel. They calculate the relationships between various parts of the ship using fractions, ratios, and...

Help young scientists connect with nature and learn about trees with a fun life science lesson. Heading out into the school yard, children choose a tree to adopt, taking measurements, writing descriptions, and drawing sketches of it in...

Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a...

Estimate and explore the length and weight of classroom items using standard measurement and scales. Students will work in groups to determine appropriate measuring tools, weigh or measure items, and record their results on a data chart....

How do dilated line segments relate? Lead the class in an activity to determine the relationship between line segments and their dilated images. In the fourth section in a unit of 16, pupils discover the dilated line...

What information can come from a box? Learners choose a data set to display as a box plot and decide whether to include the median in the calculation of the quartiles, show the outliers, and change the scale. To finish the lesson,...

Create a Height-Time plot of a bouncing ball using a graphing calculator. Graph height as a function of time and identify the vertex form of a quadratic equation that is generated to describe the ball's motion. Finally, answer questions...

Why do I have to do bean counting if I'm not going to become an accountant? The 24th installment of a 35-part module has the class conducting experiments using beans to collect data. Learners use exponential functions to model this...

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

Learners, working with their parents in real world situations, calculate to complete three word problems associated with multiplying and dividing fractions.

How can baseball and skeet-shooting be modeled mathematically? Sports lovers and young mathematicians learn how to use quadratic equations and systems of equations to model the flight paths of various objects.

How does your class measure up? Young scientists create a scale drawing of the JOIDES Resolution in a collaborative activity. The lesson incorporates mathematical principles with deep-sea exploration to focus on enhancing measurement...

Add up areas of squares to discover the pythagorean relationship. Small groups create right triangles with squares along each side. They calculate the areas of each square and notice the relationship. Groups construct other types of...

Should we be afraid of a large asteroid impact on Earth today? Young scientists estimate the size and composition of an asteroid similar to the one that caused the K-T mass extinction. They apply algebraic formulas to answer questions...

Seventh grade math is so much fun! They solve 10 different problems that include using patterns to complete a table, describe the pattern, and identify the specific term in the pattern for each. Then they give a description of the...

In this elapsed time instructional activity, students analyze a schedule of events at a picnic with the starting times listed. Students read and solve 6 problems in which the elapsed time is calculated.

RJ had an awesome basketball season this year! Use division by double-digit numbers to calculate his scoring average in this instructional presentation. Starting with an explanation of the terms dividend, divisor,...
