Review of Key to Decimals

I purchased Key to Decimals last week off Ebay. They arrived today in the mail and I couldn't wait to finally see what this Key to series was all about.

Well, my first impression was...that's why it's so cheap, no bright, shiny cover, just a paper cover. No biggie. Opening up the pages my first impression was......EWWWW. They use some old-fashioned (I'm thinking 1980s IBM Selectric typewriter font) and it was UGLY. There's also hand written problems. What I did like was occasionally there were pages with graph paper background. We use graph paper a lot in math to help DS with number size and lining things up properly.

Aesthetics are important to me and apparently they're important to DS, too. I called him over to take a peek. His first comment was, "Mom, that's ugly. Yuck." However, he sat down and did three pages on the spot and got over the ugly font.

I bought the entire decimal set. After I looked through all four books page by page, I understood why this series was so popular. It's to the point, good, solid, very repetitive stuff.

I'm sold. Ugly font and all. I will be buying the geometry set and possibly the measurement.

There's no rush when teaching a child. Mastery is a good thing, and we'll continue using our math program and then following up with work in these books.

Thanks for this review. I've been thinking about having my 11yo work through this book before moving on to Lial's. I'm going to Ebay now!

Peace, BridgetJ
