Wing Area Effects Problem Set

What is an annulus? Pupils first learn about how to create an annulus, then consider how to find the area of such shapes. They then complete a problem set on arc length and areas of sectors.

Using trigonometric ratios to solve geometry and application problems is the focus of this detailed problem set and solution presentation. The presentation covers many ways to use trigonometry, from finding missing measures in right...

Using a similar process from the first lesson in the series of finding area approximations, a measurement resource develops the proof of the area of a circle. The problem set contains a derivation of the proof of the circumference formula. 

Use a triangle area formula that works when the height is unknown. The eighth installment in a 16-part series on trigonometry revisits the trigonometric triangle area formula that previously was shown to work with the acute triangles....

What do you do when you don't think you have enough information? You look for another way to do the problem! Pupils combine what they know about finding the area of a triangle and trigonometry to determine triangle area when they don't...

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

This quick but detailed geometry problem set effectively mixes multiple choice and open-response questions. Focused on standard solids of revolution concepts to start, questions then extend to a reverse engineering of equations that...

Begin this study on the relationship between area and perimeter with the hook activity featured at the bottom of the "What Shape is Your Land?" link, which offers a fun optical trick to engage high schoolers. Learners should have a basic...

Mix it up in math class! The video provides an equation hint to be able to setup mixture problems. Two problems are provided as examples on how to use the equation in order to solve mixture type word problems. 

Radical, dude! The resource provides an explanation on how to simplify radical expressions. It makes clear that radical expressions are ones that are strictly numerical but also are algebraic expressions. One of the problem sets includes...
