This Week's Challenge
Cookies! Cookies!

Andrea decorated 20 cookies to take to a party.
She lined them up and put icing on every second cookie.
She put sprinkles on every third cookie.
She put a chocolate kiss on every fourth cookie.
There was nothing on the first cookie.

1.  How many other cookies had no decorations?
2. Did any cookies get all three decorations? How many?    
3. If Andrea kept decorating cookies, what would be the next cookie with all three decorations?
4. Out of any number of cookies, is there a way to predict which cookies will have all three decorations? Just icing? Icing and sprinkles?

Meet Zac and Zoey

Zac and Zoey are students like you. They like to think, they like to share their ideas and they sometimes disagree. They also sometimes make mistakes, but this helps their brains grow and helps them become better thinkers.

Did you know...
Making mistakes actually makes your brain grow! Every time you struggle with a problem or make a mistake and think about a new strategy to try, a new connection is made in your brain. It's like connecting two roads. So, go ahead and take on a challenge. Don't let your brain be a one way street!
