Iskra Posted October 31, 2012 Share Posted October 31, 2012 (edited) Ok, so this is a problem from Singapore 2A Intensive Practice. It is problem number 3 from "Take the Challenge" for Topic: 2. In my edition of the book it is on page 28. It is complete the pattern problem and it has 3 chains: chain 1: 9 13 5 17 chain 2: 8 12 6 14 chain 3: 10 6 5 ? What's the missing number? My son actually figured out that it is 11, but it was a lucky guess, because when I asked him to explain the pattern to me, he gave me the wrong explanation. So he definitely has not solved the problem. I want to help him get to the solution by himself, but I don't know how. I already gave him the hint that he will need to do some addition and some comparing, but that didn't help him. Does anyone have ideas of how I can guide him through the thinking process, without giving the solution away?

Night Elf Posted October 31, 2012 Share Posted October 31, 2012 How about having him write the numbers using the math symbols required, + and -. I'm embarrassed to say it took me a few mins. to figure out myself! :tongue_smilie: Quote Link to comment Share on other sites More sharing options...

KungFuPanda Posted October 31, 2012 Share Posted October 31, 2012 Build the pattern with different colored Legos so he can see what's happening. Quote Link to comment Share on other sites More sharing options...
