Choose a restaurant where you will eat (make one up if you need to). Pick at least 3 things to buy off the menu, and total up the cost of these items. Add 7% sales tax to your total, then find a 15%-20% tip on top of that to find your total cost.

A complete answer will have:

1. Name of restaurant
2. Name of each item you buy
3. Cost of each item you buy
4. How much tax you pay, in dollars and cents (What is 7% of the total of your items?)
5. What percent you tip, and what dollar amount that comes to
6. The final/total cost for your bill

I copied this post and its comments from the old blog location at Wordpress:

Here’s my (pathetic?) decimal rap:

To add decimals, you draw a line.
To divide, you move it out.
Subtract, you also draw a line.
Multiply, you have to count.

I’m pretty sure you can do better. Your assignment? Make up your own song or rap that tells how to add, subtract, multiply, and divide decimals, and post it here as a comment. Remember my post “Wrapping up decimals” — it has the key ideas that need to be included in your song or rap. If you have a different idea (other than a song or rap) for a creative way you’d like to show your learning about decimal operations, please ask me about it at school or through e-mail, and I’ll be glad to accommodate you!

Well, the first quarter is coming to a close…it’s time to reflect on what we’ve learned together. Thinking back on what you learned about in math class during first quarter, answer at least two of the following questions:

1. What was the most interesting thing you learned in first quarter, and why?
2. What was the most difficult thing you learned in first quarter, and why?
3. What did you learn this quarter that you will be able to use in your future? How will you use it?
4. How could math class be made better for the upcoming quarter?
