Homeschool Conversations-Pt.3

We are working our way through Singapore's Challenging Word Problems 1. We just got to the section on multiplication. We haven't worked on multiplication since we covered it in Primary Math 1B which was around Christmas.

So here's how two of our problems went this morning:

D-Man: That's 9x2. I have to go potty. Be right back.

D-Man: (Immediately after the quick trip to the restroom) That's 18.

Mom: That was fast, how did you know that?

D-Man: Well, I was thinking about it while I was going potty. 5-2's is 10 and another 4-2's is 8. 10 plus 8 is 18. It's really just an adding problem.

Mom: Wow, that's exactly right.

Next problem...

D-Man: (After reading the probem) That's 3x2. Hmmm...That's 10-4. It's 6.

Evidently, he thought that 5x2 = 10 and 2x2 = 4. When you subtract them, you get 3x2.

Interesting math day.

Homeschool Conversations pt. 1

This was a conversation that occurred this morning:

D-Man: (while finishing his geography) Mom, can we do my word problems book next...PLEASE?

Mom: Sure. If if that's what you want to do...

D-Man: How many pages can I do? Can I do a lot?

Mom (who has planned for D-Man to do 1 page/day): How about 2 pages? That's a lot, right?

D-Man: No, how about 5 pages because I'm 5? Can I please do 5 pages? That would be 10 problems. (He continues talking to himself) Unless I do 20 problems...then I would only have to do 5 more pages.

Mom: Okay, you can do 5 pages (as she wonders what we're going to do when he finishes this book).

D-Man: GREAT!
