Why in the heck are they making 3rd grade so hard?!?!?!?!?!?!?
Jessie brought home a math paper for homework tonight (in addition to working on her spreadsheet of presidents and important facts about them (online) and studying for 2 tests tomorrow). Want to know what the questions were?
"Solve the math problems mentally. Show wich number you would add to both, and then find the answer.
49 - 38 = _____
71 - 29 = _____
97 - 47 = _____"
So I call a teacher from the school, whose daughter happens to be in Jessie's class. No answer.
I call another parent, whose son is in Jessie's class. The parental response I haven't a freaking clue in h*** what they are doing in math. She puts her 9 year old son on the phone (who incidentally finished his math homework in school and so didn't bring it home).
After much roundabout talking between him, his mom, Jessie and I, you have to take the smaller number, add to it to get it up to a whole number divisible by 10, add the same number (that you added to the smaller number) to the other number and then subtract them.
So 49 - 38 becomes 51 - 40 = 11. And 71-29 becomes 72-30 = 42. And 97-47 becomes 100-50=50.
Now wouldn't it be simpler to just teach them how to solve the stupid problems????????
The good one though was when we got 2 calls from other friends in the class wanting to know what the heck they were supposed to do......
This ranks right up there with the problems from the other night: Estimate 789 - 543 = ___. Which we found out the answer is 300 (800-500).
