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

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 - Practice [Video - 8:58] (2011)

A learner can use this video tutorial to practise solving simple equations.

The tutorial includes three equations. Learners are asked to pause the video, solve the equations on their own, and then restart it to see the instructor’s solutions.

## 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 - Practice [Video - 6:17] (2011)

This video tutorial gives learners the chance to practise their skills at calculating the volume of rectangular solids.

It includes three problems, all based on a rectangular box. The learner is asked to pause the video, work out the problems, and then restart the video to see the instructor’s detailed solutions.

## 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 - Practice [Video – 6:58] (2011)

Learners can use this video tutorial to practise their skills at calculating the area of a shape.

It includes three sample problems that involve either a rectangle, a triangle or a circle. The learner is asked to pause the video to work out the problems on his own and then restart it to see the instructor’s solutions.

## 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.

## Teaching Fractions, Percents and Decimals Together [Video - 9:28] (2010)

This video features Linda Thorsen, an instructor with Nova Scotia’s Valley Community Learning Association, offering strategies for teaching fractions, decimals and percents to adult learners.

## Geometry Part 1 – Perimeter - Practice [Video – 5:46] (2011)

This video tutorial gives learners a chance to practise their skills at calculating the perimeter of an object.

It includes three examples, involving either a rectangle, a triangle or a circle. The learner is asked to pause the video and work out the problems on his own before restarting the video to see the instructor’s solutions.

## 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.
