Lesson Planet

#### Area of an L-Shape

Think about your shapes as tangrams as you find their areas! Scholars learn to decompose L-shaped compound figures to find their areas. A video shows how to break the figure into rectangles, and learners practice using the included...

#### Real-Life Math | Estate Appraiser

Real estate is all about location, location, location—and perhaps a little bit of math. A set of two videos has real estate appraisers describe the work that they do. Scholars discuss how mathematics plays a role in these jobs to...

Lesson Planet

#### Area of a Triangle

Base times height or one half base times height ... area formulas are pretty predictable! Given the base and height dimensions of a triangle, a video lesson explains the process of finding the area. Learners have the opportunity to...

Lesson Planet

#### Area of a Parallelogram

Find the area of a rectangle, square, parallelogram, and rhombus by multiplying the base by the height. A well-designed lesson has scholars first view a video showing examples of finding the area of a parallelogram before practicing on...

Lesson Planet

#### Real-Life Math | Woodworker

Woodworking is math-intensive work. Viewing a video of a woodworker explaining how he applies math in his craft sets the stage for a crafty lesson. Pupils use ratios and proportions to create scale drawings of objects.

Lesson Planet

#### Square Partitions

Challenge your classes while developing their problem-solving skills. A square is divided neatly into four equal triangles by its diagonals until one diagonal is moved from a vertex to the midpoint of one side. Now, scholars must devise...

Lesson Planet

#### Sticky Stickies

Don't let your classes get stuck on area calculations—grab their attention with an inquiry-based lesson! Scholars must develop a plan to determine how may sticky notes it takes to cover the surface of a door. They decide on the...

Lesson Planet

#### Bubble Wrap

Let your lesson pop by using the resource. After watching a video of a man popping a square piece of bubble wrap, young mathematicians determine the time it would take to pop other pieces of bubble wrap with given dimensions. The...

Lesson Planet

#### Boxed In and Wrapped Up

If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...

#### More Chocolate Candy?

Everyone knows that candy is the best part of any holiday—but which holiday's candy gives you the most bang for your buck? Analyze a chocolate heart, a chocolate bat, and a normal piece of chocolate to decide which piece of candy has the...

Lesson Planet

#### Buoyant Boats

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

Lesson Planet

#### What Floats Your Boat?

Clay's as good a material as any to build a boat, right? An introductory activity sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

Lesson Planet

#### Area and Perimeter of Triangles: Lesson

Go from a parallelogram to a triangle. A segment of an extensive playlist on basic geometry shows the derivation of the formula for the area of a triangle. The resource works examples that require finding a missing side or height to...

Lesson Planet

#### Area and Perimeter of Rhombuses and Kites: Lesson

Flip the triangles up and create a parallelogram. Using the idea of transformations, the video develops the area formula for rhombi and kites. The segment of an extensive geometry playlist uses the formula to find the areas of different...

Lesson Planet

#### Area and Perimeter of Trapezoids: Lesson

With a little averaging, a trapezoid becomes a parallelogram. The section of an extensive geometry playlist shows how to derive the formula for the area of a trapezoid by changing it into a parallelogram. Using the formula, the video...

Lesson Planet

#### Area and Perimeter of Rectangles: Lesson

Around and in—take a different look at rectangles. A portion of a basic geometry playlist discusses the area and perimeters of rectangles. Using the formulas, the presentation works perimeter and area examples with rectangles and squares.

Lesson Planet

#### Area of Composite Shapes: Lesson

To find the whole, add and subtract the pieces. A portion of a massive geometry playlist shows how to approach finding the area of a composite figure. The resource works with a couple different composite shapes to find their areas.

Lesson Planet

#### Area of a Parallelogram: Lesson

Sliding over a corner makes a rectangle. The resource demonstrates why the formula of the area of a parallelogram works. As part of a larger playlist on basic geometry, the video works examples dealing with parallelogram areas.

Lesson Planet

#### Discovering the Area Formula for Circles—Apple Pi

Need an activity that brings your class' understanding of the area formula full circle? The second installment in a two-part series involving geometric calculations further develops the young mathematician's measurement, approximation,...

#### Fluency Support for Grades 6–8

Fluency is more than just timed tests. A helpful resource provides a series of fluency-building activities designed for middle school mathematics. The activities come in two forms, one that uses whiteboards and a second designed to help...

Lesson Planet

#### Area

Area is a two-dimensional measurement for a two-dimensional figure. The introduction of area expands on the idea of the one-dimensional measurement of length, but instead of staying one-dimensional, it goes in two directions. The video...

Lesson Planet

#### Finding Triangle Vertices

Where in the world (or at least in the coordinate plane) is the third vertex? Given two coordinate points for the vertices of a triangle, individuals find the location of the third vertex. They read an account of fictional...
