extra credit due Monday, April 28

Here are two extra credit assignments. You can do either assignment, or both assignments. Your work in due by Monday, April 28. That is a 7th grade testing day, so if your class doesn't meet that day, just bring the assignment by between classes. Or, of course, you can turn it in earlier. 

Each question is worth 10 points. So, each assignment is worth up to 50 points. Write your answers on a paper and turn them in before the end of Monday.
