My students are really enjoying “Stories with Holes,” which involve logic and problem-solving.  These stories are not what they seem at face value because, usually, specific words in them have a double meaning.

Here’s an example:

John was afraid to go home because the man with the mask was there.

After introducing a very short story like this, the presenter asks listeners to ask “yes” or “no” questions to help uncover the true meaning of the story.

The key with this one is to think of different meanings for the word, “home,” and if you think of it as “home base,” the story takes on a whole new meaning.  Yes, the “man with the mask” is the catcher and John is playing baseball!  He doesn’t want to go home because he doesn’t want to get tagged out!

Fun, isn’t it?

Well, some of my fourth-graders had so much fun with these logic puzzles lately, they decided to write their own.  Here’s a sampling . . . can you figure them out?  Post a comment if you think you’ve solved one of them . . . or if you have a question!

There was a guy named Bob.  He was playing a game.  He got lots of strikes.  Why was he happy?

A guy goes to a birthday party, but he locks his car and leaves his present and keys in the car.  How does he get the present without harming the car or picking the lock?

(Written by Jonathan)

Bob was at a store.  He walked around the store.  Then, he was thirsty.  Why didn’t he go in to buy a drink?

(Written by Rashad)

Jake just got knocked out by Robby.  And that was the end of his practice.

(Written by Jake, Weston, and John)

When Mark walked into the kitchen, the ground was covered with blood and dog drool.  Mark could not eat dinner that night.

The light shown on Millie and she couldn’t move.

If you haven’t played the online mathematical game, KENKEN ,yet, you should try it out.  Click here to take you to the site.

KENKEN is a mathematical puzzle, similar to SUDOKU, but much more challenging, as it involves lots of mathematical operations as well, not just arrangements of digits.  There are KENKEN puzzles for every ability level. 

A student and his family turned me onto KENKEN and told me how much they’re enjoying solving these puzzles as a family.  If you give them a try at your house, please post a comment to let me know what YOU think!

Friday was “Sports Spirit Day” at Island Avenue School.  Students and teachers had fun “sporting” their favorite sports jerseys.  I asked a group of students to use some “mental Math” as a quick warm-up to  find the sum of all the numbers they saw on each other’s clothes in the classroom and they soon came up with totals in four digits!

I had fun wearing one of my son’s football jerseys.  Some of my students were quite excited to see that his team had a 10-0 season.  Here’s a riddle to find the number of my jersey:

It’s an even, two-digit number, between 30 and 60. The sum of the digits is 13.  Any guesses?

Can you make up a Math Riddle for a number of your choice?  If so, post it here!

Whatever football team you may be rooting for this weekend in the Superbowl, have fun!
