Cars in the USA are how old? Really? No way! Look at the World and Do the Math

February 3, 2018

 

The average age of the 60 years of FORD vehicles here is 30 years. MODEL NAMES at end of post.

I did this to show that averages can tell us a lot or, in this case, not very much.

Here are some averages that tell us a lot about different countries and their love of cars!

The average age of vehicles in USA is a record-high of 11.6 years. More here.

Car ownership rates data here.

This is the average vehicle age, which includes vans and utes. Almost 1,000,00 vehicles were scrapped in 2015-16. More than 30% of vehicles are less than five years old. Data here.

In 2016, the average age of vehicles on Canadian roads was 9.66 years. Data here.

The average age of cars in UK is 7.7 yrs. some interesting stats here.

The average age of vehicles in New Zealand is 14.3 years. The average age of trucks and buses is over 17 years. Data here.

Cars in the European Union are on average 10.7 years old. Data here.

The average age of vehicles in Poland is 17.2 years. Daata here.

The average age of vehicles in Romania is 15.3 years. Data here.

The average age of vehicles in Greece is 13.5 years. Data here.

Ethiopia has the lowest car ownership in the world with 2 per 1,000 inhabitants in 2014.

The average age of Ethiopia’s fleet is 15-20 years. Best guess! Data here.

6. You’re either Good at Maths or You’re Not

September 20, 2017

The Complaint:  

You’re either Good at Maths or You’re Not!………………

………………………………………………………………………….

The Cause:

Most students who said “I can’t do maths’ when I was teaching, didn’t do maths. They talked, penned a tattoo on their arm. Or scribbled in the text book. Today they read texts or play games on their phones under table or fall asleep.

………………………………………………………………………….

The Solution: 

There is no point arguing. Students must ‘see’ they can do maths.  

Do something that grabs their attention, something counterintuitive. Here is one of the BEST revision projects ever for middle school maths students. Remember, the best way to learn something is to teach it.

7. Maths is really SCARY!

September 13, 2017

The Complaint: Maths is really SCARY!………………

………………………………………………………………………….

The Cause:

Some students think maths is always right or wrong and they are scared of making mistakes.

………………………………………………………………………….

The Solution:

You are going to do maths with no right or wrong answers. You just start and see what results you get.

………………………………………………………………………….

7a. Dad Jokes: The positive, the negative and the number line

Yeah! It’s a Dad Joke!

7b.  Middle School Maths Photo Scavenger Hunt  

Whoa! Totally CRAZY! Skiing a HELIX.

It looks like a Fibonacci Spiral, but that is an illusion. Steps on a spiral staircase are always the same length!

NO! This is not your homework. No stunts. 

Just show us where you see maths in the world.

7c. Crack a Security Code for Middle School…… Yes! Really!

Prime Numbers vs The Hackers!

Note: The last challenge involves guess work. Maybe, an intelligent guess, but, maybe, not.

1. Middle School Madness: BIG MATHS

June 12, 2017

…………………………………………………….

Community Maths can involve the school community or the wider, local community. The aim is to get maths out of the classroom and make it a hands-on experience.

Set up displays, posters, demonstrations or art/maths projects in your school library, gym or school yard or take some interesting maths to the local library, strip mall, town hall, local gardens or shopping mall. It will mean planning the project, collecting the materials and making a phone call to  the local, say, librarian, but libraries, for instance, welcome community involvement.

Here are just some community maths project ideas.

MATHS POSTERS

Major maths conferences around the world have poster displays. So why not a display of students maths posters in your school library or local library or even a nearby shopping mall. And students should be present at allocated times to explain their poster to other students, parents or members of the public.

Roosevelt Middle School students Jacob Klausner and Oliver Adelson WEST ORANGE, NJ, who were finalists heading to the National MathCon Competition.

Some of the best middle school maths posters can be found at MathsCareers, UK. Here are some posters from the 2016 competitions.

MATHS DEMONSTRATIONS

Maths students can construct displays that involve interesting maths. The most amazing maths dispalys Mathspig has seen were at the 13e Salon Culture & Jeux  Mathematique in Paris. Here is LAGA Phd student Attouchi @ the 13e Salon Culture & Jeux  Mathematique in Paris.

She was showing students how to use a graph to create anamorphic projections. More detailed instructions here!!!

Palestinian Maths teacher Daina Taimina has many zany ideas. You’ll more Creative Maths ideas here.

Mentalist Maths … OK. This may include some Card Tricks … but they’re amazing. You’ll find 10 amazing Mentalist Math Tricks here.

Make some interesting cubes here.

Give students a variety of maths challenges they have to solve

like these Maths Mystery Box Challenges here.

Or let students explore some of the inspiring maths websites and pick a project. You will love the amazing German website IMAGINARY. It’s in English and has some fascinating videos!!!!!

Perhaps students could construct double pendulum like this one demonstrated at the MiMa-Museum, Oberwolfach, Germany. Mathspig can’t stop watching it. Fascinating!!!!!!! The double pendulum has some demanding trigonometry, but at the middle school level the 2D graph traced by the lower pendulum is fascinating enough (Below). And maths can provide equations for this movement. That’s impressive.
