8B students received a packet with a significant amount of practice material for chapter 4, sections 1 through 5.
The minimum requirement for Friday is section 4.3, Practice Masters B and C.
Students who find Practice Master B confusing should start with the pp. 183-184, questions 13 to 23, odd, so they can check their answers in the back of the book.
Students who received at least a B at the quarter may skip Practice Master B if they can do C comfortably. I recommend they continue on to the other included 4.3 materials.
All students would be well served to review the material from sections 4.1 and 4.2. Most are very comfortable with the mechanics of proportionality and percentage included therein, but less comfortable setting up the word problems.
