Today, I had Jay take the placement test in Perfecting the Point (the Decimal & Percent book in Mastering Mathematics). He's been working in this book, doing the section on Place Value. However, I didn't see the point in having him do the entire book, if he didn't need practice in all the areas it covers. So, I had him take the placement test, skipping the last section (percentages). He got all the problems correct in the sections on adding decimals, subtracting decimals, and multiplying decimals. He does seem to need a little more work on dividing decimals, though. So, when he's done with the Place Value pages, he'll do the sections on Percents and Dividing Decimals. Then, we'll move onto the Fractions book (Finishing Fractions). Next week, he'll also be starting on Life of Fred Decimals & Percents. Life of Fred is actually meant to have Fractions before Decimals & Percents, but Mastering Mathematics is set up to do Fractions last. So, we'll do Decimals & Percents first, especially since we'll be doing so little of the book. We will do some of the pages from the sections on adding, subtracting, and multiplying decimals. I'll have him do some for review now & then.
He is not happy about needing to do the dividing decimals section. I told him, though, that getting 3 out of 5 problems wrong on that section of the test implies that he still needs some work in that area. It could just be that he was too distracted. There was a lot going on at that time & his sister kept interrupting him. However, the section on dividing decimals is only 16 pages, so it's not like it will be too much review.
