Answer:

There will be 14 avalible teams to compete in th compition.

Explanation:

What I did first is I figured how many boys and girls there are.I did
this by dividing the total students in half. Thhen I subtracted 8 from
one half fiding the amount of boys. Then I took that 8 and added it too
the other 22 equaling 30 girls.I then made a picture of the girls boys
and girls paired up in threes. I finally looked at the graph and
figured that there are 14 teams with 2 girls left.

>You set up the problem correctly.  Let's go back to check our math.  Hint:
There are 18 more girls than boys--> what is half of 18...you say it is 8.
Good Luck,
JC

Hi Jim,

I like a lot of what you doing. Here are some general comments to think about
when responding in the forum.

1. start by greeting the student by their first name (Hi Joe)

2. Careful with your word choice. These are middle school kids.

3. End by congratulating them or encouraging them to revise and resubmit, then
sign off with your name.

4. Be consistent whether you respond above or below the student and make sure
to clean up extraneous marks.

5. Look at the expected solution. We would like them to answer the question in
a complete sentence.

6. If you ask for a revision, don't give them credit for the problem. Remember
that CREDIT means they got it right, and INCLUDE means that they answer is so
good that we want to include it in the sample solutions section.

Cheers,

Craig

Hi Jim,

Here is an example of the kind of thing we are shooting for... (of course, add
your own flavor).

Dear Fred,

Thanks for trying the problem. 14 is not quite the correct answer. Go back and
try to rexplain, more carefully each step in your reasoning. For example, why
did you subtract 8 and then add it to the other 22? What is the other 22?

Also, if you use a graph, please share it with us and explain how you use it
to get the answer. To help, try thinking of how you would explain your
solution to a student who was having trouble with it.

I look forward to seeing how you fix this one up.

Best,

Craig

Hello Brian,
    I can see that you have put some thought into your solution.  Thanks
for trying the problem.  You have set up the problem correctly, but you have
a math mistake.  Ask yourself these 3 questions:

1. Why did I add 8 to 22, then subtract 8 from 22?
2. Why did I choose the number 8...?
3. What is half of 18?

    Use theese suggestions to try this problem again. You will recieve
full credit for your second try.  I am excited to see how you tackle this
problem this time.  Feel free to ask a question at anytime.  You can contact
me directly at: jec36@drexel.edu.  Good Luck‰Ű|

Sincerely,
James

Hello Brian,

I can see that you have put some thought into your solution.  Thanks
for trying the problem.  You have set up the problem correctly, but you made
a mistake in your arithmetic.  Ask yourself these questions:

1. Why did I add 8 to 22, then subtract 8 from 22?
2. Why did I choose the number 8...?
3. What is half of 18?
4. Is your answer statement as precise as you can make it? Hint: You say the
number of teams "will be," but there can be fewer than 13. What does the
problem ask for?

Use these suggestions to try this problem again. You will recieve
full credit for your second try.  I am excited to see how you tackle this
problem this time.  Feel free to ask a question at anytime.

Good Luck!

Sincerely,
James
