Area of Compound Shapes

The measurements are all in the can. The review for the math portion of the General Certificate of Secondary Education assessments provides scholars the opportunity to review finding volume and surface area of a cylinder. Pupils work on...

A triangle, square, hexagon, and circle all have a perimeter of one unit. Eighth graders must attempt to find the area of each and arrange them in order from least to greatest areas. A terrific task for applying four different...

Seventh grade statisticians randomly select five states and then determine the mean area. The class then works together to create a dot plot of their results. 

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

Develop a strategy for adding and subtracting fractions with your classes. The video shows a procedure for adding and subtracting fractions by finding common denominators. Each example increases in difficulty.

Composite figures—because everything isn't shaped like a rectangle, triangle, or circle. Learners practice separating compound shapes into something more manageable. A video shows them how to make the calculations, and worksheets give...

Trapezoids can be tricky! Break down the process of finding the area of a trapezoid with an engaging math video. Learners explore area formula and shown exactly how to plug in information, solve, and simplify. 

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...
