Math problems of the week: 6th grade Everyday Math vs. Singapore Math

I. From the second-to-last assignment in the 6th grade Everyday Math Student Math Journal Volume 1, p. 205:


In this unit, you had the opportunity to learn a second way to construct circle graphs. Which geometric tool do you find easier to use, the percent circle or the protractor?

Which activity in this unit do you believe is an example of your best work?

Which activity in this unit did you find the most challenging? Explain why.

What is something new you learned about geometry in this unit?

II. From the second-to-last assignment in the 6th grade Singapore Math Primary Mathematics 6A workbook, p. 103:

Ali had $120. He had $45 more than his brother. After his brother spent some money on a toy, Ali had twice as much money as his brother. Find the cost of the toy.

There were 20% more boys than girls in a swimming club. After 50 girls left, there were twice as many boys as girls in the club. How many boys were there in the club?

III. Extra Credit

The student who used my copy of the Everyday Math Student Math Journal (before I acquired it through Amazon used books) had the following answer to the third question:
The part when you have to use a protractor I think because I don't understand how to use it.
Is this the kind of answer that the authors of the Everyday Math program are shooting for?
