Changing 8 percent to a decimal… it’s .0008, right? You take 0.08 and divide it by 100.
I thought the “do it once, not twice” would work but then… “Move the decimal two places” with a very, very, very careful and explicit Placing Of The Point, explaining that 8 dollars is not the same as 80 cents…. yes, we got this. We got this.
Okay, do it.
The number is written 8. (I think: now it’s 8.0 but I think I added that.) The student looked at it, wrote another dot before the 8, and moved it twice. 0.008, indeed.
I *think* adding the 0 will ameliorate…
