7th grade proportional relationships

Grades 6–7 (ages 11–13) · 24 videos · Checked and refreshed daily

Quick answer

In 7th grade (ages 12–13), students learn to find unit rates, spot proportional relationships in tables and graphs, and write equations like y = kx. Lessons come from Khan Academy, Math with Mr. J and Math Antics' "Ratios And Rates". Loop one worked example with A–B, slow it to 0.75×, and repeat it until it clicks.

What should a 7th grader be able to do after this unit?

They should compute unit rates, including rates with fractions, decide whether two quantities are proportional from a table or graph, find the constant of proportionality k, and write an equation such as y = kx. The playlist starts with rates, then tables, graphs, equations and word problems.

How does an A–B loop help with proportional relationships?

Many Khan Academy videos here are short single examples. Loop the moment a teacher reads k from a graph or table, and it replays on its own. Save each example on keys 1–9, and use Stop after N loops to keep a review session short.

Frequently asked questions

Is this the same 7th grade unit every school teaches?

Grade levels vary by country and school. In the US, proportional relationships are usually covered in 7th grade (ages 12–13). Elsewhere the same topic may appear a year earlier or later, so use the playlist wherever it fits.

Where should a student start?

Start with Math Antics' "Ratios And Rates" and Mr. J's unit rate lessons, then Khan Academy's "Introduction to proportional relationships". Finish with the word problem and proportion-solving videos at the end.
