Italian Street Painting Fair

This weekend the Italian Street Painting Fair is happening on Saturday and Sunday from 9 am -7 pm. It’s a wonderful fair and relates nicely to the enlargement the 7th graders are doing.

This weekend is also the RoboGames, an international robotics competition. MVMS is having a team going. We will be competing between 12-3 and 6-8. The competition is at Fort Mason in Building F.

Halloween is Coming

Halloween is coming and beside the overflow of sugar there is also a lot of garbage generated. Why not be original and create your own costume from things that you have or go to a thrift store and make a costume. Speaking of “make things”, here is how to make yourself into a zombie from Make Magazine. The guest artist is Eric Beck from Indy Mogul, a company dedicated to Do-It-Yourself (DIY) movie effects. Eric was one of the four gurus that was in the DIY meeting at YouTube that I went to this summer. He’s very creative. Check out some of the fun ideas on the Indy Mogul channel. I like the backyard rain machine.

Marin IJ Article about MVMS Robotics Team

Here is an article about the MVMS Robotics Team printed in today’s Marin Independent Journal.

Next Saturday the team will be competing in the Robogames at Fort Mason. If you have time, come out and check out the amazing things robots can do… and support your classmates. Tickets are $20 for adults and $15 for kids 7-17. I hope to see you there.

Lego Mindstorm Robots

As we wrap up the unit on robotics, a number of you have asked me where to find the kits. Here’s a link to the Lego Mindstorm kits.

People who like robotics and building things will also want to make sure they go to the Maker Faire next year. They had a whole building dedicated to robotics. You may also enjoy the podcast by Bre Pettis of  Make Magazine. Check out Mousey the Junkbot and Safety Ninja.

If you enjoyed the robotic unit, feel free to apply to be on the robotics team next year. The main event we’ll be participating will be from September to January with the Lego First. The focus will be on using technology and robots to solve ecological problems.

This is probably the last post of the year. Enjoy! You can also request to get deleted from the emails by looking at the bottom of the post.

Have a  fun summer!

Candy Math

Happy New Year!

 

If you liked Chocolate Math, then you’ll enjoy this puzzle that I created called Candy Math. Can you figure out why it works?

I’ll give you a hint, I am a math teacher and I love equations.

 

 

 

 

 

YOUR AGE BY CANDY MATH

This is pretty neat.

DON’T CHEAT BY SCROLLING DOWN FIRST!

 

 

It takes less than a minute.

Work this out as you read…

Be sure you don’t read the bottom until you’ve worked it out!

This is not one of those, waste of time things.

It’s fun.

1. First of all, pick the number of times a week that you would like to have candy (more than once but less than 10).

.

.

.

.

2. Multiply this by 4 (just to be bold) .

.

.

.

.

3. Add 9.

.

.

.

.

.

4. Multiply it by 25 — I’ll wait while you get your calculator. (See if you can do it mentally. It’s not that difficult if you think of 25 as one fourth of 100).

.

.

.

.

.

.

5. If you have already had your birthday this year, add 1782 …

If you haven’t, add 1781.

.

.

.

.

.

6. Now subtract the four digit year that you were born.

.

.

You should have a three digit number.

The first digit of this year was your original number (i.e. how many times you want to have candy each week).

The second two numbers are YOUR AGE! (Oh YES, it is!!!!)

.

.

.

.

.

This is the only year (2007) it will ever work, so spread it around while it lasts.

Can you figure out why it works? We’d love to hear your comments.

Fractions & Percent-Decimals-Fractions Test

The fractions, percents-decimals-fractions & multiplying & dividing monomials test is day 4 of this week. Math Tutor: Fractions is a great resource to help you prepare. This website that I created has tutorials, videos and fun games to teach you about fractions and how to change from fractions, decimals to percents. I’d love to hear your comments about the site. Leave a post.

If you haven’t see the YouTube video on multiplying and dividing monomials, I recommend it highly. It will help you to avoid common mistakes.

Multiplying & Dividing Monomials

A monomial is a single term. For example, 3x, -5xy and 7 are all monomials. When multiplying and dividing monomials, it’s a helpful to write the problem in expanded form. a^2*a^3 = a*a*a*a*a = a^5. (That looks weird. I’ll be happy when blogging supports math software!)

For a quick reteach of multiplying and dividing monomials, check out this video. It also discusses common pitfalls to avoid. [YouTube=http://www.youtube.com/watch?v=Z6T1BtXKZbs]
