Dear Fellow Classmates,

As we all know, the school spring carnival is the most exciting event of the year. Among all the exciting activities during the carnival is the opportunity for our class to outshine the 7th and 8th-grade classes. There is an inter-class competition for the most creative class booth. I know it seems a long way away, but now is the time to start planning. Some of us have some great ideas that we think will get us 1st prize. I cannot share these ideas here in the letter, but you can ask me about them in person if you are curious.

We need to start raising the money that we will need for our class booth right away. One of the reasons why the higher grades usually win is they have higher quality stuff. Therefore, I have a proposal on how we can raise enough money for what we need. I suggest we all volunteer to rake leaves for donations. There are just over a 100 of us in 6th grade and if we all find two houses that would donate $5 each to our class booth, we will have more than enough to build a great booth. Additionally, since most trees have just started dropping their leaves that should make it easy for everyone to find homeowners willing to help us out.

Here's to the best spring carnival yet!
