In this video Paul Andersen shows you how to use mathematical and computational thinking in a mini-lesson on mathematical representations. Two examples are included in the video and two additional examples are included in the linked...

Pupil outcome: I can appreciate the connection between multiplicative relationships and direct proportion. Key learning points: - Direct proportion can be represented on a graph. - Direct proportion can be represented on a double number...

Pupil outcome: I can identify, write and solve direct proportion questions involving algebra. Key learning points: - Direct proportion equations are of the form y = kx - k is the constant of proportionality and it is also the gradient of...

Pupil outcome: I can identify and solve proportion questions involving algebra. Key learning points: - The question does not always state the type of proportion. - The context of the question can be used to determine the type of...

Pupil outcome: I can identify direct proportion graphs from their features and can use the graph to create an equation to algebraically model this relationship. Key learning points: - Direct proportion can be recognised graphically. - A...

Pupil outcome: I can convert between metric and imperial speed measures. Key learning points: - Sometimes speed is measured in different units. - Approximately 17 countries (roughly 9%) use mph. - When travelling abroad, it is useful to...

Pupil outcome: I can use my knowledge of direct and inverse proportion to solve problems. Key learning points: - Algebraic manipulation is needed to solve proportion problems. - Proportional relationships can be modelled graphically and...

Pupil outcome: I can use the general form for a directly proportional relationship to find k. Key learning points: - Direct proportion equations are of the form y = kx - k is the constant of proportionality and it is also the gradient of...

Pupil outcome: I can recognise direct proportion graphically and be able to identify features of the graph. Key learning points: - Direct proportion can be recognised graphically. - A direct proportion graph is always a straight line. -...

Pupil outcome: I can use the general form for the directly proportional relationship y = kx^n to find k. Key learning points: - y can be directly proportional to x^n - This is because x^n could be written as a different variable.

Pupil outcome: I can recognise direct proportion graphically and can interpret graphs that illustrate direct proportion. Key learning points: - Direct proportion can be recognised graphically. - The equation of a direct proportion graph...

Pupil outcome: I can recognise direct proportion in a range of contexts, including compound measures. Key learning points: - Direct proportion can be used in a number of contexts. - One context is converting compound measure. - Another...

Pupil outcome: I can recognise direct proportion in a range of contexts, including compound measures. Key learning points: - Direct proportion can be used in a number of contexts, for example in currency conversion. - Proportional...

In this video I will show you how to use direct variation to help determine the missing variable, as well as how to determine if an equation is an example of direct variation or not. For an equation to be an example of direct variation...

This video is a presentation on proportional relationships and graphs. The speaker discusses direct and inverse proportion and provides examples along with constant rates of change. They also explain how nonlinear functions can create a...

This video provides an explanation and examples of interpreting gradients as rates of change. The speaker discusses how the gradient of a line can represent the rate of change, with steeper lines indicating a greater rate of change. They...

This video explains the concept of direct proportion and how to solve problems related to it. The lecturer explains the mathematical language associated with direct proportion and provides examples where it can be applied. The video then...
