Mrs. Rubenstein and I have coached The Crazy 8's Math Club since 2017.

We meet after school, once a week. Bedtimemath.org is the creator of Crazy 8's. We love the opportunity that Crazy 8's shares with our Brooks Hill Students. If you know a parent that is interested in learning more about Crazy 8's, please email me. Thank you, sreindel@fairport.org

Our CRAZY 8's Math Club Kiddos know that MATH ROCKS!

We have started our first ever session of

CRAZY 8's Math Club.

Please check out the website for Bedtime Math. This is a FANTASTIC resource for children and families!

What is Crazy 8's Math Club?

The goal of Crazy 8's is to show that math is fun and recreational, not compulsory, in order to change our culture and get kids to think of math as play. Crazy 8's is a recreational after-school math club that helps kids enjoy the math behind their favorite activities! With that in mind, clubs always take place outside regular school hours, during the school year. Our club meets at school after dismissal from 3:30-4:30.

How often does the club meet?

Clubs meet weekly with the same group of kids. Another major goal of Crazy 8s is to make math a fun, social part of life for kids and their friends. Research has shown that the repeat math experience has a much greater impact on kids, so we to commit to a weekly schedule (with the occasional week off for holidays, etc.). All clubs meet once per week for 8 weeks. Our club meet for about an hour each week.

How is all of this funded?

Crazy 8s is funded by the Bedtime Math Foundation, a private, nonprofit organization dedicated to putting the fun and discovery back into learning math. In addition, all royalties from founder Laura Overdeck's Bedtime Math books go back into the foundation to support Crazy 8s and our other programs. CRAZY 8's sends us all materials and plans for our club. (You will note information on this Crazy 8's section of the web page is directly from CRAZY 8's. ) We feel very fortunate to be able to offer this club at Brooks Hill School. THANK YOU Bedtime Math Foundation!

Week 1 Glow-in-the-Dark Geometry

Our team members created many geometric shapes using glowsticks. We explored all sizes of triangles and quadrilaterals. Then we laid out mystical repeating patterns on the floor, OOOOOOOOOH, how awesome!

What’s the Math?

★ 2-D geometric shapes

★ Counting

★ Area

★ Pattern recognition

Week 2 Let’s Get Loud !

We used straws to generate different sounds, then made a pan flute out of milkshake straws. Can you see our performers lined up to serenade us? Imagine the beautiful sounds we heard. Finally, we got to yell into a decibel-meter and found out how loud we could be - using math the whole time to create funky music!

What’s the Math?

★ Comparing and sequencing lengths

★ Relationships between variables

Week 3 Time of Your Life

This week our team explored time in different increments, from lining up in birthday order, to being a clock, and racing against the clock trying silly stunts!

Can you see the clock numbers on the floor? Our kiddos created 2 amazing human analog clocks!

In the photo on the left they made 10:30. Notice how Elizabeth is the shorter hour hand with her knees pulled up. Addy is the minute hand which is stretched out to be much longer.

The next photo shows 4:00. The third clock is working to show 4:00 also.

What’s the Math?

★ Units of time

★ Time measurement

★ Time estimation and accuracy

Below you see some silly stunts. Stop watches recorded the time it took to do jumping jacks, and a few other silly things. Time sure flies when you're having fun with math!

We all are enjoying CRAZY 8's, and can't wait for next Tuesday when we'll get crazy with brand new toilet paper!

Yes, really....The Toilet Paper Olympics are coming to Brooks Hill Crazy 8 Club. Stay tuned for more math adventures.

THANK YOU PARENTS for your weekly pick ups. Feel free to "pop" in early to see what we're up to. You are welcome to join us any week as we make mischief with math.

Week 4 The Toilet Paper Olympics

“Welcome to the Toilet Paper Olympics!

For once we get to unroll toilet paper at top speed! Have you ever used a ruler or measuring tape to measure length? Today we’re going to compete in Olympic events – and use toilet paper to determine the winners!”

So, we began with The Long Jump and The Shot-Put events...

"Let the games begin!"

What’s the Math?

★ Counting

★ Measuring lengths; units of length

★ Estimation

★ Bonus: Single-digit multiplication and division

Did you know that our toilet paper measures 4 inches long, and 4 inches wide? Here is Elizabeth making a long jump. Noah and Mariam are measuring her jump. We measured by counting the number of toilet paper squares even with Elizabeth's heels. Then Mariam jumped. Noah and Elizabeth are measuring. Can you guess how far Noah's jump was?

Next you see our team estimating, then measuring the circumference (the distance around) their bodies.

Here are some estimates, and the actual total of our measurements. (Remember that we are measuring by squares of toilet paper, which equal 4 inches square.)

Child Estimates Actual measurement

Emily 12, 15, 21 TP squares 11 TP squares

Melody 6, 16, 15, 9 TP squares 11 TP squares

Brooklyn 15, 20, 13, 8 TP squares 13 TP squares

Sonia 12, 20, 21, 16 TP squares 11 TP squares

Alex 10, 14, 13, 21 TP squares 9 TP squares

Mary 16, 10, 14 TP squares 10 TP squares

Noah, Elizabeth and Mariam are showing you how long their TP is when stretched out on the floor. See them holding up their fingers to show you the amount of squares their strip measures. They compared the length of each strip.

Here our students becoming mummified! How many TP squares do you think this took? A LOT!

Here you see Addy doing the Shot-put. After her throw, we marked her "landing spot" with tape. Then she began to measure the number of TP squares... this was taking a long time. So, we decided to do the math to figure it out! Her throw was 31 inches less than 10 feet. See the math below....(pretty awesome work!)

Week 5 Spy Training

This week we’re going to learn how to be spies by solving coded messages, cracking codes to find treasure. We might even design a code for our parent's phone number!

What's the Math

★ Number recognition

★ Pattern recognition and completion

★Logical Thinking

Our pals at Bedtime Math sent us this introduction:

“Numbers are awesome, especially if you’re a spy using them to break secret codes. So let’s train to become number expert, mystery-cracking spies!”

...And we did!

Week 6 Flying Marshmallows!

This week we made marshmallow catapults out of plastic spoons, popsicle sticks and rubber bands.

What's the Math?

★Distance measurement

★ Comparison of numbers

What is a catapult?

A catapult is a simple machine that works a lot like a seesaw.

What fun! We made marshmallows fly through the air....or at least thump through the air.

After we created our popsicle stick, rubber band and spoon catapult, the fun began!

We used a pencil first as our fulcrum. Later we tried out a chunky marker as the fulcrum. It sure made a difference in the distance our marshmallow flew. It was hard for us to measure our distances because we were so excited that we often forgot to mark exactly where our white sugary snowball first landed!

Week 7 Zip Line Zoo!

A zip line is a long, long cord that stretches from a high point to the ground, and normally people ride down it. But today we made zip lines for our stuffed animal buddies!

This week our Bedtime Math friends asked us this question:

“Does anybody know what gravity is?”

Here's an answer: “It’s a force that pulls things to the ground."

What's the math?

★ Measuring distance and time

★ Basic relationships between distance, time and speed

Today we understood that sometimes we have to grapple with a problem in order to make it work better.

After measuring out out zip line ropes, and creating a safe harness for our critter, we began our zip lining.

We began our zip line at 4 feet. But, our animals did not travel far, fast. Mostly, they didn't travel much at all. Hmmmm, what to do?

So, we brainstormed, and remembered about gravity, we decided to change the height of our zip line. With a steeper fall, we felt that gravity would help our animals gather up enough speed and zip right down.

It was a good things our animals were not afraid of heights! We raised our zipline to 9 feet! We began our zip line at the top of our bathroom door!

Weeeeeee! We could almost hear our critters scream with excitement as they buzzed down at high rates of speed. They now had momentum!

It was a beautiful sight!

Week 8 Bouncy Dice Explosion !

This is our last week of session 1.

Thank you for participating!

On our last Tuesday, we tossed bouncy rubber dice to see what numbers we rolled. We played a comparing game to see who’s the high roller. (We called it Compare, some people call it War.) Finally, we moved onto a giant human Bingo board, where we rolled 2 dice and picked any number that could win! How high can a dice be tossed?

What’s the Math?

★ Counting

★ Addition

★ Subtraction

★ Frequency (Probability)

★ Strategic thinking

Bedtime Math asks:

★ “What’s the highest sum that 2 dice could add up to?”

★ “What numbers could you roll with 2 dice to add up to 7?”

Mrs. Rubenstein and Mrs. Reindel made an incredible discovery with us...

Are you ready for this?

The opposite sides of a die adds up to 7!!! I

Imagine working with dice all these years, and we didn't know that before CRAZY 8's. We were also delighted to learn that the dots on dice are called "pips."

THANK YOU CRAZY 8's!

Sam Bowley, a sixth grader at JP assisted us with our CRAZY 8's sessions. He was very helpful, as well as fun and friendly. We all said "THANK YOU SAM" for joining us with this awesome mug filled with chocolate treasures.

Thank you Bedtime Math for making these math adventures possible. Remember, MATH ROCKS, especially when you're "rocking out" with CRAZY 8's!

Thank you kiddos for joining us,

Mrs. Rubenstein and Mrs. Reindel
