# Learning on Demand: Numeracy - The Basics - Video Tutorial

## Averages - Practice [Video - 6:36] (2011)

This video tutorial gives learners a chance to reinforce their knowledge of averages by trying three progressively more challenging problems. They are asked to pause the video to work out the problems on their own, then restart it to see the instructor’s solutions.

## Averages – Concept [Video - 12:29] (2011)

This video tutorial uses a variety of examples to introduce the concept of averages.

## Ratio & Proportion - Practice [Video - 8:46] (2011)

This video tutorial provides an opportunity for learners to practise solving problems involving ratio and proportion.

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

## Ratio & Proportion - Concept [Video - 8:46] (2011)

In this video tutorial, the instructor explains the concept of ratio and proportion, describing it as simply comparing one thing to another. It can be written as a fraction or as two numerals separated by a colon.

## Solving Equations Part 2 - Practice [Video - 11:06] (2011)

This video tutorial offers learners the opportunity to practise solving 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 detailed solutions.

## Solving Equations Part 2 - Concept [Video - 10:24] (2011)

In this video tutorial, the learner begins working on more complicated equations, including ones that contain fractions.

The instructor provides step-by-step solutions to three equations, each one more challenging than the one before.

To solve one equation, the learner has to apply the order of operations to calculations contained within brackets.

## 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.
