Maths isn’t TOO HARD; it’s TOO BORING, Sir!

Lego Mathspig 2

Hello my little Peeps,

In 2012 The New York Times ran an article by Andrew Hacker titled ‘Is Algebra Necessary?’ The argument was, basically, that too many students find algebra difficult and colleges in America use math results to screen students thus further disadvanting already disadvantaged students. The author had a point. eg. Of all who embark on higher education, only 58 percent end up with bachelor’s degrees. The main impediment to graduation: freshman math.

Perhaps, algebra could be taught in a different way. Mathspig was inspired by New York Grade 3 teacher, Alycia Zimmerman, who uses Lego to teach fractions (See next post) and came up with the following examples.

Lego Mean, Median and Mode

Lego Algebra

But Mathspig has always lerved Lego Maths. Here are just a few examples;

Ratios: Lego Olympics

Ratios: The Rosetta Project Scaled down to a Lego Universe

Other links to Lego Maths.

And while you are doing your Lego Maths you an also use the Lego Template to design your own Lego Figurine.

Lego Mean, Median, Mode

January 15, 2016

Students can calculate the Mean, Median and Mode using Lego. Here is the exciting part:

The lego stacks become the graph

START with 40 LEGO BRICKS

Draw a graph of No. of Blocks Vs No. of Prongs (per block) Make sure all blocks are the same height.

Mean median mode Lego 1

Start with 40 bricks.

Mean median mode Lego 2

Sort into Stacks to create graph of

 No. Prongs Vs No. Bricks

Mean median mode Lego 2a

This is a close up of the stacks above.

Mean median mode Lego 3

The no. of bricks in each stack is written on top of the stack.

Lego Mania 1: Going Loopy

May 29, 2012

As part of our Mid-year/ End of year madness here are some crazy things to do with Lego.

The idea with these projects is to challenge you, my pretties, by giving you  the Lego, the time and the inspiration so you can go, go, go for it and, maybe even, surprise yourself.

…………………………………………………………………………………………………………

1. Going  Loopy

Can you make something round from oblong Lego blocks?

…………………………………………………………………………………………………………

…………………………………………………………………………………………………………

You will find more awesome Lego Loops at Discovery News and more cool curves and loops @ Sanders Brick Bending Blog

…………………………………………………………………………………………………………

2. Going Bloomin’ Crazy

Lego constructions can move. Here is The Blossoming Lotus built by the Brickengineer. If you click on this link you can see the Lotus blossom. Cool! Can you make a Lego flower bloom, mathspigs?

But if you really want to see some Lego flowers bloomin’ get yourself down to the Reiman Gardens @ Iowa State University. They have the Lego flowers, the Lego birds, the Lego butterflies, a Lego Zoo. Perhaps, mathspigs, your class could put your heads together and make a Lego garden or a Lego Zoo.

……………………………………………………………………………………………….

..

…………………………………………………………………………………………………………

3. Going Square

Lego artist Nathan Sawaya’s Lego sculptures are mind boggling. You can find the following sculptures @ sayhi-todesign blog spotto or @ Nathan’s own blog, The Art of the Brick. Maybe, mathspigs, you could build a geometric sculpture out of Lego blocks.

…………………………………………………………………………………………………

Or get inspired by Nathan Sawaya’s other sculptures

Wow! That’s just how Mathspig feels when I’m waking up in the morning.

Lego Mania 2: Going Musical

May 29, 2012

Another way to get your brain wrapped around the idea of symmetry, 2D patterns and 3D image rotations is by building a musical instrument and some of them even play music, um, sort of!

……………………………………………………………………………….

1. Lego Harpsichord built by a kid

with ordinary Lego that works!!!


2. Lego Electric Guitar that really works

……………………………………………………………………………..

 3. Lego Flute that works

They say it works. Mathspig hasn’t heard it. The kid could be just spending time blowing on a Lego block.

More @ Izakoo Blog Spot

……………………………………………………………………………….

4. Lego Cello

Here is another art work by Lego artist Nathan Sawaya. The cello doesn’t play music, but this is such an awesome video of Nathan building the cello, it is a MUST see, mathspigs.

……………………………………………………………………………….

5. Lego Guitar

This one is by Patrick Dube

It doesn’t play music, but think about it mathspigs. It would look soooooo cool sitting in your bedroom. Besides, many a guitar sits in a bedroom without being played.

……………………………………………………………………………….

6. Lego Saxaphone

Here is another work by Pat Dube. It doesn’t play music but it’s just cool, man. Put on those sunglasses, feel the vibe and chill.

Lego Mania 3: Going, Going, Gone!

May 28, 2012

Now mathspigs, let’s get mobile.  There is a lot of symmetry and 3D rotations involved in building a Lego ca. You can go low -tech or high tech. Get ready mathspigs here we go:

1. Lego Balloon Car

 I don’t think you’ll need instructions for this one. Maybe you could pimp that ride, mathspigs.

……………………………………………………………………

2. Lego Rubber Band Car

You will find instructions @ eHow     

……………………………………………………………………

3. Cool Lego VW

Ramping up the challenge, how about building a Lego street car.

If you have a Lego Car Kit you can make a really cool VW and a cool video clip as well:

……………………………………………………………………

4. Lego Street View Car 

If you are the ultimate geek then this is the Lego car project for you. It could take years, mathspigs, but worth the sweat.

……………………………………………………………………

5. Lego Bike

Or just get on your Lego bike.

Get Ready for the Lego Olympics

February 23, 2012

Get ready mathspigs. You need one Lego Man, Girl, Vampire or Alien each for this exercise. Now we are going to set out the Lego Olympics Athletics track.

……………………….

But this story of the Olympics begins with Carl Lewis, one of the greatest athletes of all time who won 9 Olympic Gold medals in 100m, 200m, relay and long jump.

.

Carl Lewis

Mathspig needs to find out how big the Lego Olympics track would be. How? Easy.

Carl Lewis will be our standard Lego Man.

I chose Carl Lewis because he kindly gave me his autograph once when I sprinted in high heels across a ballroom floor at a sports dinner in Melbourne and beat all other journalists.  It was my personal best in high heels, I think.

……………. 

Lego Olympics to Scale2016……….

………

This means everything at the Lego Olympics  will be

1:50

of the real Olympics.

The Lego Beijing Water Cube Swim Centre will be 1/50th of the Real Water Cube.

EXERCISE 1:

Now mathspiggies over to you. The first thing to do is calculate the Lego Olympic measurements (table below). 

………………………………………………………..

EXERCISE 2:

Then mark out a Lego Olympics 100m sprint to scale and/or

draw a Lego Olympic track (in chalk, perhaps) and/or

step out a Lego Olympic marathon track and/or

make a pole vault pole to scale for your little Lego Man.

Or bring in a Lego Man/Girl/Pirate and step out the Marathon Track (840m to scale).

This little guy has to run 840 m!!!!! Wow!

1. Flag Fractions

EQUIPMENT: Mixed Lego Blocks

Here is the maths. It’s fractions. It’s simple.

………………..

…………………………………………………

A. National Flag of  Comotosia

They’re a bit sleepy in Comotosia so you better design a flag to wake them up, mathspigs.

The flag must measure ………….   6 blocks x  12 blocks.

One block is a 4 bumps blocks (See pic). An 8 bumps block equals 2 blocks.

……………………

Here’s the catch, mathpiggies.  1/4 of the blocks in the flag must be RED.

How will you do this? (Hint below)

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

…………………………………………

.B. National Flag of Bordom

Once again the Bordonians need a lively flag.

The flag must measure 6 blocks by 12 blocks, but this time it must contain 1/4 red and 1/3 blue. How do you do this?

Hint: Mathspigs! You will have to count the number of red and blue blocks.

 

2. Design A National Flag to Lego Scale

First, name your Lego man, girl or alien and pick a name for their country, planet or crypt.

You will be drawing two flags.

All national flags are rectangles except Switzerland and Tibet, which have square flags but not at the Olympic Games.

Olympic Flags measure:  150 cm x 90 cm

or …………………………….. 60 inches x 35 inches.

These sizes are not equal so which flag is bigger the decimal flag or the Imperial Units flag?

The Imperial units flag is 152.9 cm x 88.9 cm. It turns out the area of the Decimal flag is 13,500 cm2 and the Imperial Flag 13,593 cm2

You will be designing a decimal flag.

Note the Flag ratio of length: width = 150 : 90

…………………………………………………… =  15 : 9 = 5: 3

First design a flag with 5: 3 ratio.  One measuring 10cm x 6 cm would be ideal.

 

BUT

How big are the national flags at the Lego Olympics:

Real flags at the Olympics =  150 x 90 cm

Lego Flag measurements =  150/50 x 90/50 = 3 cm x 1.8 cm = 30mm x 18 mm

Here are my two Lego people with flags  I prepared earlier:

The Enforcer from the Constellation of Obeymia and Mr Boopy from Bozonia.
