Barbie Bungee: A Maths Investigation

Last week we completed one of my favourite maths investigations. Basically, we tied a string of rubber bands around a Barbie Doll's feet and threw her out of a really tall window . . .

In reality, it's a lot more sophisticated. Barbie Bungee is an investigation which covers a number of mathematical skills and strategies, but with my Year 5s and 6s really served to teach them that a) patterns can be graphed and b) predictions can be made from these graphs.

To complete this investigation the class was broken into four groups (I have 4 Barbie dolls), given a Barbie Doll each and a whole pile of rubber bands which were the same size. We then broke the investigation into steps which were completed over a few days.

Step One: Students learned about the investigation. They practiced tying the rubber bands (one looped around another then pulled through), thought about how they were going to take measurements (grabbing 30cm rulers, 1m rulers and tape measures) and practiced throwing Barbie from various places (important to get this need out of their system) We also talked about the goal - to throw Barbie from the sound box in our school hall, getting her as close to the ground as possible without touching . . .

Step Two: Taking our initial measurements. Students staked out the best spots and dropped Barbie with one rubber band, two rubber bands, three, four and five rubber bands (and so on). They were required to complete three tests at each stage and then find an average (for accuracy) and they had to record their information in a table. This took one to two days. The best thing I saw during this was the use of different measuring methods (sticky taping two measuring tapes together) and creative placed to drop Barbie (out the classroom window).

Step Three: Graphing the results: Students used their results to make a graph (number of rubber bands against distance fallen). They then used this graph with it's almost straight line to predict how many rubber bands they would need.

Step Four: Test Day. We took the students and an audience to the hall and each group had three goes at tossing Barbie from the sound box. The measurements (how close to the ground) were averaged and the closest to the ground won. All in all, very entertaining and a fabulous time. We did a small write up afterwards - what steps did we take, what maths was involved, but nothing too much.

A great investigation.

Children's Book Week Recommendations: A Wrap Up

Here are the five books I recommended over the last week:

Juggling with Mandarins by V.M. Jones
Mahtab's Story by Libby Gleeson
Artemis Fowl by Eoin Colfer
CHERUB series by Robert Muchamore
Mail Order Ninja by Joshua Elder

I'm also going to add a special teachers book which arrived from Amazon.com on Friday and I devoured yesterday. The Reading Zone: How to Help Kids Become Skilled, Passionate, Habitual, Critical Readers by Nancie Atwell was a short, easy read which let me know what elements of Reader's Workshop I was getting right and where I might be able to make improvements. It also includes notes to the children and to the parents which would be invaluable in setting up Reader's Workshop next year.

Even before I read this book, I was intending to review Reader's Workshop with the children tomorrow. I think this book will be invaluable in providing alternative ways of 'doing stuff'.

Children's Book Week: Day Five: Mail Order Ninja

Check out Day Four: CHERUB Series

So, Book Week has wrapped up at our school, although my class doesn't do our craft activity until Monday. And that brings me to the fifth book of the week, which is actually a graphic novel. This book isn't an assigned reading, nor is it a book I'm reading to the students. Rather it's one that's being passed around and adored as soon as it's read.

Mail Order Ninja by Joshua Elder is one of my growing collection of graphic novels. It tells the story of Timmy, the graphic novel (not comics) obsessed boy who detests bullies, 'trust-fund queens' and his bratty sister. When he finds an advertisement for a Mail Order Ninja, he has to get it. The ninja then helps him clean out the bad elements of the school.

The first one has been in my class for a couple of months now, and I just received the second one from Amazon.com. What I love about this series is the way it's drawn, there's an awful lot of information for the students to gain from it and it's a very smart book. There's also a lot of sly humour that adults would appreciate.

I highly recommend this graphic novel, especially if you're putting together a collection for a classroom.

Children's Book Week: Day Four: CHERUB

Check out Day Three: Artemis Fowl

Day four is slightly late due to a little 9 and a half hour sleep :) But after a highly successful Book Day (with lots of brilliant costumes) I'm going to talk about one of the most successful series of books in my classrooms.

The CHERUB series by Robert Muchamore is a British series based around spies, who also happen to be children. The main character, James Adams (formally James Choke) is a gifted 12 year old, particularly in maths, but is always in trouble. When his mother dies, he is put in a home and steadily moves towards the criminal element. Until one morning when he wakes up in the nicest school campus he has ever seen.

There is a wide cast of characters in CHERUB, including some strong female characters and characters from diverse backgrounds. The books deal with missions ranging from environmental terrorism to unsolved deaths to gang setups. The books do grow in maturity with the ages of the characters, so some of the later ones may not be appropriate for younger children. (I have the first couple in my room, but the later ones are usually bought by parents who also read them :) They are universally popular)

What I have found with these books is that they get reluctant male readers to read - or devour. When I began reading the first one to the Year 7s I had last year a lot of them got their hands on their own copy to read themselves. I recommend these to 12 years and older, though some more mature 10 and 11 year olds could probably handle them too.

There's also a prequel series The Henderson Boys which is set during World War 2 and is really good :)

Children's Book Week: Day Three: Artemis Fowl

Check out Day Two: Mahtab's Story Here

And so we move on to day three, the halfway mark of children's book week. Today we're actually going back two years to a time when I taught contracts for terms rather than having my own class. At one point in time I had a non-gifted (but still some quite bright) class of grade 5s. Knowing I'd only have them for a term, I needed something which would grab them quickly and keep them going, but would be easy to complete in 10 weeks.

Enter Artemis Fowl by Eoin Colfer. Artemis is a genius. A criminal mastermind. And a 12 year old boy. He wants gold, but not just any gold - he wants fairy gold. And he's willing to kidnap to get it. On the opposing side is Holly Short, pointy eared and occasionally neglectful of the more important things. Also, desperate to prove herself in the male-dominated LEP-recon world.

This really is a scream of a book - fantasy, action and comedy all poured into one. For reading outloud it's perfect, with plenty of opportunities for voices. I was also able to tell immediately at one point which children were really listening - they were the ones who knew there was a rip-snorter of a fart joke coming.

I've had a few kids really get into reading through these series of books and others simply devour them. Well worth a read, but even better to read out loud.

Children's Book Week: Day Two: Mahtab's Story

Check out Day One: Juggling With Mandarins here!

Onto Day 2 of Children's book week, with a book we're studying now. At the moment we're focusing on Theme, Genre, Audience and Purpose. The students are all required to read four books that cover themes such as family, children on their own, survival, conflict, bravery etc. One of these books is Mahtab's Story by Libby Gleeson.

Mahtab is a young girl in Afghanistan, before September 11th. She's terrified of the Taliban, the men in black, who rule over the streets. She's not allowed to go to school, she's not even allowed to leave her home. After the death of her grandfather, her father begins to make plans for their departure to a country he's heard of - a place called Australia.

There is some beautiful writing in the beginning - some of the most descriptive writing I've read in a children's book, which just sort of picks you up and carries you along. The setting of the story is quite universal, there are refugees all over the world. However, there are some parts which really sit within an Australian context, with recent debates over 'boat people'.

The ending seemed a little rushed to me, which was an opinion shared with the students. I think we all wanted to know more about Mahtab's settlement into an obviously strange country. However these discussions about what makes a good story or a good ending are just as important.

This is another book I'd recommend, particularly if you are doing any work on Afghanistan or on refugees.

Children's Book Week: Day One: Juggling With Mandarins

So this week, as many of you in the Northern Hemisphere are heading back to school, is Australian Children's Book Week. To celebrate this, I'm going to point out some of the books I've read to and shared with my students over the last couple of years.

Today's book, Juggling With Mandarins by V.M. Jones is one I read to my Grade Sevens last year. It is a New Zealand story about Pip, the 14 year old who's good at English and bad at soccer. Sadly, it's soccer his gruff father cares about, and soccer where his older brother Nick excels.

While Pip deals with the expectations and often irrational behaviour of his father, he's also also handling his growing feelings for the girl next door. Then he discovers the new sports centre, the Igloo, and its special climbing gym.

This was a great book to read with 12 and 13 year old students who are dealing with the experiences of finding themselves and defining themselves as separate from their parents. We did some work in class with it - mostly vocabulary and writing - but most of the time we just enjoyed it. If you can get your hands on it, I'd thouroughly recommend it for whole class and small group work.

Summer in Winter (and other stuff)

So, it's supposed to be winter here in Australia. Unfortunately, today's temperature is supposed to reach 33 degrees Celsius. Classrooms in my part of Queensland don't have air conditioning, and they're rarely well ventilated, so I'm afraid today might be a little uncomfortable.

Luckily, we're doing heaps of fun stuff, which makes it easier. In maths at the moment we're Bungee jumping Barbies. This is basically an exercise to show the children that they can graph algebra patterns, and that they can use these to make predictions. Then it's about throwing Barbie from something tall.

We also begin our astronomy Unit today in which the children will finish up by making a model of a community for Mars. Lots of science in this one, but today we're beginning by listening to famous 'space related' music and talking about what we know - should be a blast.

Returning to class - again

So, I've been away at training to learn more about Coolabah Dynamic Assessment, which is, quite honestly, some of the most exciting stuff I've learned about in gifted education in the six years I've been reading and learning about it. But now it's back to school.

After three days away, I'm a bit nervous about what's been happening in my classroom. Will it be an absolute mess? Will the supply teacher have kept up the work while I've been away? Has anything happened that I needed to know about.

There's also the next, big thing I need to prepare for - our school's Poetry in your Pocket day. I need a funky way to announce it to the students and the teachers- and I must get it done by next week. Help!

New Carnival of Education

One of my favourite things about coming to education blogging has been the Carnival of Education. Now Clix from Epic Adventures are Often Uncomfortable has pointed out that Blog Carnival is listing the Carnival of Education as discontinued :(

Luckily, Clix is willing to do something about it and has set up EduCarnival v2. But she needs help!

"What's a carnival without articles, after all? Email me at uncomfortableadventures at yahoo dot com with a direct URL, or use this handy-dandy form to submit your article."

She'd particularly after summer reflections and she needs them by next Monday. I've submitted my mini-series on Reader's Workshop but it's your turn now. Go. Now. Now!
