This video introduces basic concepts related to statistics, focusing on the idea of variables. Variables are defined as numbers or characteristics that can be counted or measured. The video gives examples such as age, length,...

A video entitled "Compose Functions" that covers the concept of substituting one function into another to form a composition of functions.

A video entitled "Coefficient" that covers the concepts involved in solving equations where the variable has a coefficient.

A video entitled "Rearrange Radicals and Rationals" that shows how to use inverse operations to isolate various variables in equations.

Solving differential equations can get pretty tricky, but in this modern age we have some tools that can be very useful. We can use computers to carry out sophisticated numerical methods that can solve any differential equation, no...

Howcast - An algebraic equation is an equation that includes one or more variables. These equations can be solved as long as the number of variables does not exceed the number of equations.

Isolating a variable is a matter of separating and simplifying.

When looking at branding there are internal and external perceptions of brands and we look at things we can be flexible with and things we can't be flexible with, so if you are looking at your brand vision this is internal and our brand...

Pupil outcome: I can use variables to store values and trace how they change in a program. Key learning points: - A variable is used to store a value in a program. - A variable can be updated with a new value which replaces the initial...

Pupil outcome: I can use condition statements in selection to control the path a program follows. Key learning points: - Conditions are built using expressions that evaluate to either True or False. - Selection provides program control...

Pupil outcome: I can interpret line graphs representing two variables. Key learning points: - A line graph is a way of representing the relationship between two variables. - One variable is represented by the x-axis and the other by the...

Pupil outcome: I can construct line graphs representing two variables. Key learning points: - A line graph is a way of representing the relationship between two variables. - One variable is represented by the x-axis and the other, by the...

Pupil outcome: I can use the distributive law to multiply an expression by a term. Key learning points: - The distributive law can make multiplication easier. - The distributive law can be understood using an area model. - A bar model...

Pupil outcome: I can carry out an investigation into friction and evaluate the results. Key learning points: - Scientists carry out investigations to measure and compare the amount of friction created between different surfaces. - The...

Pupil outcome: I can explain why it is important for a plant that its seeds are dispersed over a wide area, and carry out an experiment to measure seed dispersal. Key learning points: - Seeds are dispersed by different mechanisms to...

Pupil outcome: I can plan to investigate variables that may affect the brightness of a bulb in an electric circuit. Key learning points: - A variable is any one thing in an investigation which could be changed. - Adding other components...

Pupil outcome: I can recognise that a letter can be used to represent a specific unknown or a variable and know the difference. Key learning points: - A letter can be used to represent a specific unknown in a variety of ways. - A letter...

Pupil outcome: I can use a letter to represent a generalised number. Key learning points: - A letter can be used to represent an unknown number in context. - A letter can be used to represent a variable number in context. - A letter can...

Pupil outcome: I can use my knowledge of expressions and equations to solve problems Key learning points: - Standardised notation is important when using algebra. - Algebra allows us to generalise real life problems. - Algebra allows us...

Pupil outcome: You can explain how to use representations to calculate unknown values. Key learning points: - Bar models can represent unequal sharing or many to many sharing with three variables. - Representations show the relationship...

Pupil outcome: I can appreciate how to maintain equality between two statements. Key learning points: - Bar models can be used to compare expressions. - If the expressions are equal the bars will be the same length. - Operations can be...

Pupil outcome: I can consider the implications of installing solar panels. Key learning points: - The size of a property determines how many solar panels can be installed - The amount of energy generated depends on the a variety of...

In this video, we define direct variation and work an example problem.

In this video, we work examples of exponential growth and decay regarding colonies of bacteria and radioactive decay. We will find the "k" value, and solve for it using logarithms. These exponential word problems are very similar to...
