How to calculate percentages.
Percent simply means out of a hundred, and once that clicks, the three percent questions (find the part, the whole, or the percent) stop feeling like three separate formulas. Study Butler builds all of them from that one idea.
Here is what that looks like.
Study Butler will not print the answer. It points at the next step and lets your kid take it.
An example. The butler answers the question with a question.
what is 20 percent of 60.
percent means out of a hundred. so what is 20 percent as a decimal, and what do you do with it.
0.2, and multiply by 60?
exactly. you have got it.
Where students get stuck.
The same few mistakes come up again and again. Here is where the butler slows things down.
01Forgetting to convert the percent first
Students multiply by 20 instead of 0.2. Study Butler always has your kid turn the percent into a decimal or fraction before anything else.
02Mixing up the part and the whole
In percent-change problems, dividing by the wrong number flips the answer. The butler asks which number is the original, every time.
03Confusing percent of with percent off
A 20 percent discount is not the same as paying 20 percent. Study Butler slows down to check what the problem is actually asking.
Bring the problem they're stuck on.
Type it, say it, or snap a photo. Study Butler walks your kid to the answer one question at a time, so they learn it instead of copying it.
