## Think Aloud in Mathematics [Video - 6:09] (2010)

Featuring Kate Nonesuch, Literacy Educator and Curriculum Writer

This video features literacy educator Kate Nonesuch, explaining how an instructor can use thinking aloud to help adults learn math.

She uses a math problem that involves determining what percentage one number is of another. As she looks at the problem, she discusses aloud the points the problem raises; estimates her answer; and draws a diagram to help in her calculations.

## Solving Equations Part 1 - Concept [Video - 13:12] (2011)

This video tutorial provides an introduction to mathematical equations.

The instructor explains that an equation contains an “equals” sign and must be solved for a variable. The goal is to make the left side of the equation equal to the right side.

The instructor solves a number of increasingly complex equations, providing step-by-step instructions for each one.

## Geometry Part 3 – Volume - Concept [Video - 13:25] (2011)

This video tutorial provides an introduction to the concept of volume in geometry. The instructor explains that volume is the amount of space an object takes up. For example, the amount of space available for storage inside a box is the volume of that box.

Volume is always measured in cubic units and involves calculations that include the three dimensions of length, width and height.

## Geometry Part 2 – Area - Concept [Video - 19:04] (2011)

This video introduces the concept of area, which the instructor explains is simply the amount of surface an object covers.

He focuses primarily on right-angle triangles, rectangles and circles, calculating the area for one example of each of those shapes.

He points out that in order to calculate the areas of those shapes, it is essential to know and remember the necessary equations.

## Geometry Part 1 – Perimeter - Concept [Video - 12:07] (2011)

This video tutorial introduces the concept of perimeter, the distance around an object. The instructor notes that while any object has a perimeter, he is limiting this tutorial to triangles, circles and rectangles.

For the triangle and rectangle, he simply uses a ruler to measure the length of the sides, then adds those figures together to come up with the perimeter.
