    Here is a question my 8 year old daughter is expected to answer for tomorrow. I'm no genius, but I can't for the life of me explain to her how to solve this one. IMHO it's beyond Grade 3 math, but that's a WHOLE other topic.......:mad: :mad: :mad:

    Fred and John are playing a game with their friends. Fred has 16 more chips than John. John and Fred have won 44 chips altogether. How many chips does each of them have?

    Could you please show me the steps to solve this one? Thanks......
    :crazy:

    44 total chips minus 16 that fred has = 28 chips for john and 16 for fred ?

    Wrong. Fred has 16 more chips than John.

    Don't worry, I know the answer but I figured it out by trial and error. I'm not sure how my 8 year old is supposed to be able to magically figure it out if grown adults can't.........

    This is grade 3? I'm almost sure I did this in grade 9. (so i might be rusty, but its something like this)

    Johns chips = x
    freds chips = y

    we know

    x + y = 44

    y = x + 16


    Both are simple equations that can be graphed from there to find the solution, or you can substitute

    x + (x + 16) = 44
    or 2x + 16 = 44

    2x = 44-16
    2x = 28
    x = 28 / 2
    x = 14

    See, thats how Kanada is gonna get us in the end. When I was in 3rd grade, we were still on animal flashcards. "No Allen, thats a berd, ya see dem thar wings, ya see, elafants don't got 'em no wings." I'm thinking about suing the Georgia public school system.

    That would explan the gentle gnawing I hear coming from the front door. Too bad you choose to wage war with Beavers. I don't see the 3rd Beaver Battalion, 3rd Quadraped Brigade, 2nd Rodent Airborne Division winning too many battles in the future.

    easy to explain how to do it with out elgabra, 44 chips total, 2 kids, one has 16 more than the other

    44/ 2 kids = 22 each
    22-8 (half the difference of chips)=14
    22+8 (again, half the difference)=30

    30+14=44

    i think i did this kinda stuff in 4th or 5th grade, but don't remember. ill have to ask my mom what she teachs her kids for math, she teachs 5th.

    You need to think about it in terms you understand.

    Fred and John drank 44 white russians. Fred drank 16 more than...

    Wow,

    Sharp mind. I never thought of doing it that way. I did the whole algebra thing and kept thinking the entire time that if third graders in Canada know this stuff, they're waaay ahead of us. Well, all except for one 3rd graders Daddy!

    I love math problems, bring on more 3rd grade homework!!

    Man, I gotta reach back 30+ years to solve this one;


    X=44
    2Y+16=44
    44-16=2Y
    28=2Y
    14=Y(John's number of chips)
    Y+16=Fred's chips
    30=Fred's chips

    Third graders have it tough up there. My daughter in third grade is just starting her multiplication tables!!!

    How do you come up with 2Y+16=44 from the original question?
    Fred and John are playing a game with their friends. Fred has 16 more chips than John. John and Fred have won 44 chips altogether. How many chips does each of them have?

    They wouldn't have survived the night. One of them, Fred, probably would have died of alcohol poisoning.

    How much alcohol you figuring was in each portion of white russian they each drank?

    I compartmentalized it:

    44 total chips, remove 16 to make the distribution equal, there are 28 remaining chips to evenly distribute.

    28 chips evenly divided between 2 individuals equals 14 per individual.

    Fred and John both have 14 chips. Add the 16 removed from the total to Fred's distribution, and he will have 30; 16 more than John, while the total distribution remains 44.


    I dont think this is beyond 3rd grade. We're probably overthinking it, which is what makes it appear more difficult than it is. I looked at the formulas and didn't even try to understand them... :rotfl:
