Middle school special ed. math. They'd been working on menu math. (Wow, this really works for M-day!) It was quiz day.
The teacher and instructional assistant realized that the students might have issues with the format of the quiz, so they decided to address this with a warm up. That looked exactly like the quiz.
We took it slowly. We gave them time for each of the five questions. #1 listed the items they'd order. How much did that cost (the subtotal)? We checked to make sure every student got that right before moving on to numbers 2 & 3: How much for the tip (assuming 20%) and tax (assuming 8.5%).
Once those were correct (and that meant that they all calculated it and got the right answer), they were to find their total bill. And finally #5, they were to figure out how much change they'd get back if they used a $10 bill.
Everyone got there with us. We helped them figure out what to do for each question, and we checked to make sure every student got those questions correct. Then we passed out the quiz.
The quiz looked just like the warm up. The only difference: the items chosen from the menu.
And... Some of them bombed it.
One student who seemed to easily complete the warm up was completely flummoxed. She was adding 0.20 and 0.085 to the subtotal. (Well, at least she converted percent correctly.) Others stared at the questions, unsure what to do.
Clearly, they're still not comfortable with the concepts. Sigh. It'll come. Eventually.
How are you at figuring percents? What sort of tip do you leave for your servers? We're at the halfway point this month--how's your April going? Is A to Z flummoxing you?
