For those who want to hear the tricks that were hard for my child: Number In The Middle such as 8+6 is the same as Doubles 7+7. While this is useful and needed information, I think conceptually, this was a lot for my 7-yr old to switcheroo. Also a bit hard, Magic Nine, BUT she already had a handle that if she subtracts 10, then adds one back, she'll have it. So here, my girl had her own trick, and one shouldn't mess with what works. Nevertheless, DON'T let these minor criticisms deter you from buying--your child may love these tricks too OR you'll work through them like I did. The point is that IF you run into a difficulty like mine, you can manage it. A great, very well put-together book! I thank you wholeheartedly Susan R. Greenwald! (And shortly, on to the Multiplication book!)
There is no adding or subtracting of two double digit numbers (10+25 or 20-12 equations), but there are plenty of adding and subtracting of double digit numbers with single digit numbers. There are also a lot of tricks to adding and subtracting, many of which I never learned and found were really helpful! This is a wonderful book for any kid who needs a little more help on math at school, or for home schooling kids. Highly recommended.
Finally, my daughter is successful. She doesn't have to memorize math facts, but learns the facts by looking for numerical relationships (i.e. next to each other). After practice tools that build these skills she quickly sees the patterns presented and no longer has to depend on rote memorization and recall.
Well, now summer session just started. I give her my own homework over the summer. I pulled this book back out. We had sporadically done it before and jumped around in Tier 1. I decided to start with Tier 2.
We're doing it! It's not learning, it's just finger addition for her-until she learns the rule. Learning the rule (and having to say it for each cumulative practice problem) takes it a step higher intellectually-and she does the book now!
In class, she had timed fact tests with similar problems. I wish we had used the book them! Next year will be multiplication facts. Addition is needed for that and almost any math problem. I'm so glad we have this book and I'm praying we finish it!
This fall, I'll get the multiplication fact book.
