World Math(s) Day 2011 - March 1st

By , February 19, 2011 2:23 pm

The annual world mental arithmetic challenge is back! March 1st is World Math(s) Day.

Teachers can sign up their classes, homeschoolers and parents may register their children also. There are levels for ages 4-18 and your kids can help set a new world record of one billion correctly answered questions!

Kids have 48 hours (as long as it is March 1st somewhere in the world) to complete up to 100, 60 second math games. Students who answer the most questions correctly will be listed in the hall of fame.

Jealous of your children’s math fun? This year there is an adult category too (ages 19-119).

There is also the option to turn this into an easy fundraiser with 50% of the earnings going to your school and 50% to UNICEF. Download a fundraising pack for more information.

Register now to participate. It’s FREE!!

PS. If math isn’t your thing, how about joining World Spelling Day on March 3, 2011?

NOTE: Registration closes the day before on the 28th of February; however, registration is unneeded if already registered for Mathletics, Spellodrome, VmathLive or World Spelling Day as the registration for those will work for World Maths Day.

Cool Math

Do you have a reluctant math student? Unfortunately I have two of them. My 7 and 9 year-old are stuck in that very tedious phase of math where everything seems to be all about drilling problems. According to her recent parent-teacher conference, my 4 year-old on the other hand, currently spends much of her time in the “math environment” of her Montessori classroom. As her proud Mom, I have of course already planned out her future career as an engineer!

The foundation of math can be pretty boring. I remember that from my school days. Fortunately I ended up loving math later, and even took it in college.

I keep thinking, if only there was some way to make it clear to them that math can actually be really cool later on, then perhaps they’d be willing to slog through this early stuff until the light bulb comes on for them as it did for me.

Fortunately I recently discovered the math stories by Theoni Pappas. I bought Fractals, Googols, and Other Mathematical Tales (that’s some of the cool stuff!) and The Adventures of Penrose the Mathematical Cat (my kids love cats).

I have begun reading the fractals book out loud with my oldest daughter. We have read several chapters and she keeps wanting more! Each short chapter has an easy and creative explanation of a different complex, mind-bending concept presented in story format. Often there are related activities to do, or puzzles to solve. At the end of the chapter is a highlighted box with more complete information about the concept, usually involving history or practical applications.

The Möbius strip was one of the real WOW chapters that we have read so far (see our photo above).

Will these books turn my children in to math-lovers? Who knows, but they are fun!

Join in World Math Day! (March 3rd, 2010)

By , March 2, 2010 4:59 pm

Teachers and parents, are you looking for a fun and different math activity for your students or kids? Then you’ll be happy to learn that tomorrow, March 3rd 2010, is World Math(s) Day!

Teachers can sign their classes up to participate in this online math contest with same-aged students (5-18 years) from around the globe for a chance to win prizes. Individual students or homeschooling families can register too. This year for the first time there is even a category for teachers and parents who want to join in the fun. Plus, it is all COMPLETELY FREE!

Here is how it works:

“Students play at home and at school against other students around the world in live games of mental arithmetic. Each game lasts for 60 seconds and students can play up to 500 games, earning points for each correct answer. The students who answer the most questions appear in the Hall of Fame. Students cannot select their level but will move up as they progress.”

(“About World Maths Day,” from the World Maths Day website)

So far there are over 2 million students from 37,000 schools in 200 countries registered for tomorrow’s event. The goal is to beat last year’s world record of correctly answering 452,681,681 questions!

I had fun just browsing the lists of students and classes registered from an amazing array of locations. It would make for a great geography lesson in addition to the math fun!

Head on over right now and register your students, children, and yourself!

Geometric - String Pattern Art (Weekly Unplugged Project)

By , August 30, 2009 9:55 pm

The theme for this week’s Unplugged Project was geometric.

Inspired by this article from Family Fun we made geometric string patterns. However, not being able to resist changing instructions, we did it a little bit differently.

The article uses painted wood panels and nails. While this would certainly produce a sturdier and probably more striking result, I didn’t want to mess with sawing and painting, so I came up with a simpler alternative: foam board and straight pins.

You’ll need foam board, colored yarn, scissors, and pins.

Cut the foam board into a 12 inch square. The edges were messy so I bound them with red duct tape which actually made a nice frame.

Trace around a dinner plate onto a piece of paper to get a perfect circle. Cut out the circle. This will be your pattern for placing the pins.

Fold the paper circle in half four times and unfold. You should have 16 evenly spaced creases. Lightly tape the circle to the center of the foam board.

Stick a pin in at the top of each crease touching the edge of the circle. The pins will be sticking out pretty far, but that will give you lots of room to wrap the yarn. (NOTE: We experimented with cutting the pins in half to make them shorter, but they kept falling out and didn’t leave enough room for multiple strands of yarn.)

Remove your paper pattern and choose your yarn.

Tie the end of the yarn onto the top pin (the “12 o’clock pin”, let’s call it number 1). Create a repeating pattern and wrap your yarn. For example, moving clockwise, skip two pins and wrap around number 4, then go back to the next pin over from the “12 o’clock pin” (number 2) and wrap, moving clockwise, skip two more pins and wrap, etc. This pattern would be: 1, 4, 2, 5, 3, 6, 4, 7, etc. (NOTE: Pattern in the photo below is different, don’t get confused!)

Work all the way around the circle. When you are finished you should have a nice design. Cut the yarn and tie the end onto the last pin (should be the 12 o’clock pin).

Tie a new color onto the 12 o’clock pin and proceed with a different pattern. Any pattern at all is fine as long as it repeats itself all the way around the circle of pins. We found that three different patterns were all the pins would hold comfortably.

The article suggests putting a dab of glue on the knots. We didn’t bother, but probably would have if we had gone all out and done the wood and nails method.

My 9 year-old daughter loved this so much that she made two other little ones in the corners of her board:

My 3 and a half year-old enjoyed it too. I gave her a small piece of foam board, stuck pins in for her, and told her to do whatever she wanted.

This was the result:

She was very proud and couldn’t wait for me to take a photo!

USEFUL TIP: Remove all cats from the room. Much to everyone’s aggravation, Pita The Adventure Cat enjoyed this project tremendously:

OTHER IDEAS: You don’t have to use a circle. Try triangles, squares or rectangles. Try different numbers of pins. If you really want to get fancy, you can even make these in three dimensions!

Fun Wooden Math Game (Toy Recommendation)

By , February 26, 2008 5:58 pm

Santa gave the 4 Way Countdown Wooden Game to my 7 year-old daughter because he was hoping it might be a fun way to work on memorizing math facts.

The board consists of a simple square wooden box. Each side has ten wooden numbered bars that flip up and down. The object of the game is to be the first to flip up all your numbers. Players take turns rolling two dice. They can add, subtract, multiply, or divide the two numbers appearing on the dice in order to equal a number on one of their bars. They then flip up that bar. To make things a little more interesting, if you roll and eleven, you can of course flip up the 1 (6-5=1) or, instead, make another player flip all their bars back down. Fun, but beware: if you roll a twelve, then you must flip down all your bars!

This makes for a surprisingly entertaining game. What I like best about the game is how it can grow with your child’s abilities. Younger children can play by simply adding and subtracting. Multiplication and division can be added later as math skills progress.

I must also mention that even I like playing this one. Since many games aimed at children are deadly boring for grownups, I am always excited to find one that is at least tolerable, at best fun.

So, did Santa pick wisely? Yes! This game makes basic math facts easier to memorize and is way more fun than flash cards. Thank you Santa!

4 Way Countdown is also fairly practical as a travel game. The box is about 10.5″ x 10.5″ and 1.5″ thick, doesn’t weigh much, and the only loose pieces are the two dice. Dice are rolled inside the box, so are unlikely to escape during play.

Great math practice for 2 to 4 players (or you could even play alone). It would also be a great addition to a homeschool classroom.

PS. My daughter just saw me writing this post and wants to play 4 Way Countdown now. I’ve got to go so we can get in a quick game before dinner!
