Angles play a big role in the Mr. Math Puzzler questions for June.

Questions 3, 5 and 6 all involve figures with different types of angles. Knowing how to figure angles will be a key to a successful entry. There are basic formulas about angles in a polygon and the relationship of the sides in a triangle.

Then, you’ll need some understanding of principles concerning circles and cubes.

More kids entered the May competition and there was one winner. The number of entries probably went up because everyone was back from spring break. There were schools on spring break for much of April.

But, Mr. Math Puzzler says there’s room for lots more entries. Mr. Math Puzzler is Wayne Hesse of Green Park Lutheran School in south St. Louis County.

He’d be happy if kids from every school in the metro St. Louis area were to enter. Of course, judges for the Young Saint Louis.com contest might not be quite as happy when faced with a deluge of entries.

But, YSL.com encourages everyone to tell their friends about the competition. Maybe you can get together and have some fun trying to figure out the answers.

Before trying, however, you ought to check with some of answers to past questions. You can do that by clicking on Past Stories on the Home Page. Then, pick any month from September, 2001, on.

Each month, there is a story that gives the answers to the previous month’s questions.

Then, after some study, you’ll be ready to enter this June contest.

A reminder: These Math Puzzlers can be quite challenging, especially for younger kids. Remember, we don’t mind if you get help from a parent or older brother or sister. In fact, you might want to make this a family activity.

Here’s how to enter:

1. Print out the following entry form.
2. Fill out your name, address and telephone number.
3. Give your answers to the six Math Puzzlers.
4. Put your completed entry into a stamped envelope.
5. Mail your entry to:
