How does an A–B loop help with percent word problems?

Most percent videos solve several problems in a row. Loop just the one your student is stuck on, from reading the question to the final answer, and it repeats on its own while they follow how the percent becomes a decimal or fraction and gets multiplied.

When should a student slow a lesson to 0.75×?

Slow down for the setup of a proportion or a percent change, where a teacher quickly decides which number goes on top. At 0.75× there is time to copy the setup, then play the rest of the example at normal speed.
