In this video Paul Andersen shows conceptual thinking in a mini-lesson on proportional relationships. TERMS Quantities - the amount (or number) of a thing Proportional relationship - relation of one dataset to another dataset Directly -...

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, write and solve inverse proportion questions involving algebra. Key learning points: - Inverse proportion equations are of the form y = k ÷ x^n - k is the constant of proportionality. - To find k, you can...

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

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 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 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 read values from various scales and convert between units of measure. Key learning points: - Reading values from scales in a useful skill in a variety of contexts. - Different countries may use different...

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

In this video, we practice direct, inverse, and joint variation problems.

Electrical conductivity varies from metals to insulators. Solids can be divided into three categories: conductors, insulators, and semiconductors. Conductors are solids through which electricity can flow to a large extent, classified as...

Bohr's atomic model postulates that the radius of an electron's orbit around the nucleus is determined by the concept that electrons travel in quantised orbits with distinct and well-defined radii. According to the model, the angular...

In this lesson, we will compare their learning features to understand the fundamental difference between a kid and a computer.
