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 -...

In 1972, U.S. Congress passed Title IX, a law which prohibited discrimination against women in schools, colleges, and universities -- including school-sponsored sports. Before this law, female athletes were few and far between, and...

Pupil outcome: I can appreciate that there are an infinite number of pairs of numbers for any given multiplicative relationship. Key learning points: - There is a multiplicative relationship between the ratio parts, and other equivalent...

Pupil outcome: I can use a double number line to represent a multiplicative relationship and connect to other known representations. Key learning points: - A bar model is a representation of a multiplicative relationship. - A double...

Pupil outcome: I can use proportionality as a comparison rather than just absolute values. Key learning points: - A smaller percentage of one number can be greater than a larger percentage of a different number. - Proportionality offers...

Pupil outcome: I can use a graph to represent a multiplicative relationship and connect to other known representations. Key learning points: - A multiplicative relationship given algebraically can be represented on a graph. - From the...

Pupil outcome: I can express a multiplicative relationship as a ratio or as a fraction. Key learning points: - By expressing the multiplicative relationship as a ratio, it can be easier to scale further. - The relationship can be...

Pupil outcome: I can form equations from algebraic ratios and solve to find an unknown. Key learning points: - Equivalent ratios have a scalar multiplier. - Two equations can be written which are simultaneous. - This can be set equal to...

Pupil outcome: I can calculate percentage changes (decrease). Key learning points: - A bar model can be used to find a percentage decrease. - A double number line can be used to find a percentage decrease. - A ratio table can be used to...

Pupil outcome: I can use a scaling diagram to represent a multiplicative relationship and connect to other known representations. Key learning points: - A double number line can be used to represent a multiplicative relations. - Double...

Pupil outcome: I can understand and use the language and notation of ratio and use a ratio table to represent a multiplicative relationship and connect this to other known representations. Key learning points: - A ratio table is a...

Pupil outcome: I can calculate percentage changes (increase). Key learning points: - A bar model can be used to find a percentage increase. - A double number line can be used to find a percentage increase. - A ratio table can be used to...

Pupil outcome: I can interpret scaled drawings in a variety of contexts. Key learning points: - Maps are a practical example of a multiplicative relationships. - The scale factor is the multiplier. - The multiplicative relationship can...

In this video, I’ll show you *two easy methods* to determine whether two ratios (or even a whole table of values) are proportional: ✅ *Simplifying Ratios* – Reduce each ratio and compare! ✅ *Cross Products Property* – Multiply across and...

In this lesson, you will be creating a scroll with a torn paper effect in Blender.

In this math video we will learn how to compare & interpret a graph. We will connect unit rate to slope or constant of proportionality on the graph. We will write an equation using the unit rate. As we compare two lines on the graph we...

In the recent New Zealand Election, Prime Minister Jacinda Ardern’s Labour party came away with almost a majority of the vote, but from this, they will get an absolute majority in Parliament, so how did they manage this and turn 49% into...

Your friends might believe that Physics is dry and boring, but we’re going to prove them wrong! In subtopic 1, we’ll design theme park rides, such as rollercoasters and the rotor (aka the gravitron). Then, in subtopic 2, we’ll journey...

Gravity is a heart-warming story of attraction. These farm animals would fall for each other even if the laws of Physics stop working! This lesson will formally revisit the gravitational force (from year 11), focusing on Newton’s Law of...

This video explains about Basic Proportionality Theorem with the help of an activity .

In this video lesson, we cover proportional relationships and slope, including how to graph equations and interpret slope in the context of a problem. We also discuss comparing relationships and using different representations to...

This video explains how to write an equation that represents the proportional relationship between distance and time. It demonstrate how to find the unit rate by dividing the total distance by the total time. The video clarifies that...
