Looking for an engineering project that will tower above the rest? Try a design experiment that has built-in fun! Groups examine a variety of skyscraper designs, then compete to create their own slender towers. The teacher's guide is...

Young mathematicians practice measuring and graphing skills while working in groups to measure objects found in the classroom. Using their measurements, they create one bar graph displaying the lengths and another displaying the widths.

Take a coordinated look at rectangles. The task asks pupils to plot the length and width of created triangles in the coordinate plane. Using their plots, scholars respond to questions about rectangles and their associated points on the...

Five questions—multiple-choice, fill in the blank, and discussion—make up an interactive that challenges scholars to mail a teddy bear using the smallest box possible without squishing it. A box with movable sides allows mathematicians...

Estimating whole number multiplication and division is the focus of an interactive that uses a garden plot with moveable points to answer six questions.

Model finding the area of a rectangle using a helpful video lesson. Young scholars watch as the instructor shows how to find the area of a rectangle. Additionally, the instructor shows how to calculate the length or width when given the...

Writing expressions is a basic skill of algebra—but it's a skill that causes scholars to struggle. A thorough video provides examples and explanations to help individuals understand the process. From defining the variable to representing...

Roll right along with an informative lesson that makes cents. Scholars learn that some shapes roll without any change in its width. The video in the Numberphile "Coins" series starts with two-dimensional figures, such as Reuleaux...

Give your scholars the support they need to work with formulas. A reference page offers definitions and picture examples of perimeter, area, surface area, volume, the Pythagorean theorem, a variety of shapes, and more. 

Finding the area of a rectangle is the focus of this metric worksheet. Here, mathematicians use their knowledge of finding the area of a shape in meters to discover how much material can fit inside a shape.

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry lesson plan. Through a series of problem solving exercises, children use their math knowledge to design different-sized garden plots that...

It's not a complicated word problem, but the picture frame just gives the problem a little context. So you are trying to find the difference, which means subtraction. The instructor reviews how to distribute the negative sign to the...

Length times width times height. Yes, the formula for the volume of a rectangular shape. But the values are monomials. Use the knowledge you have to multiply the monomials and then write it in simplest form.

It's not a complicated word problem, but the picture frame just gives the problem a little context. So you are trying to find the difference, which means subtraction. The instructor reviews how to distribute the negative sign to the...

The teacher illustrates a diagram to help you learn about perimeter. First she adds the sides together to get the perimeter. Then she shows how to use the perimeter formula to make it a bit simpler.

Area=Length x Width. Locate the value of the length of the rectangle and locate the given width and plug them in to solve. Don't forget to include the units and multiply them too.

Area=length x width. Locate the value of the length of the rectangle and locate the given width and plug them in to solve. Don't forget to include the units and multiply them too. This three-minute video can be watched at home to review...

Learn how to use the formula for area to solve a problem about a rectangle. The demonstrator shows how to plug in the known values of a rectangle, and then how to use the formula for area to solve for the variable in question.

Discover how to find the algebraic formula for the perimeter of a rectangle through this tutorial. Your algebra learners will be guided towards the thinking steps around this concept. After showing the video, invite your class to model...

Yards or inches? Understanding measurements has a lot to do with units, so give scholars some scenarios and have them choose the appropriate unit. There are six labeled images here requiring weight, distance, length, and capacity. They...

For each of these eight rectangles, scholars write out the multiplication sentence to find the area given the side measurements. They use an example for reference and must remember to include square feet in their answer. All measurements...

Each of these rectangles and squares has the length and width given with units. Can scholars solve for the area? Designed for beginners to this skill, all of these are whole-number single-digit measurements. There is a detailed example...

Using just the measurements of ten rectangles, scholars match them to their calculated areas. Each of these is measured in feet, so the areas are labeled with square feet. The lengths and widths here are double and triple-digit whole...

These rectangles have everything scholars need to find the area, but none of them has units. Beginners to this skill multiply the length and width, all of which are whole numbers, to calculate and record the area for each. Consider...
