A Question about the Alphabet

May 10, 2013 · 1 Comment · Finding Out, Maths

Over the school holidays Mrs S was doing some research about grammar and vocabulary. She found a book called Blake’s English Guide for Primary Students. It contains alphabetically arranged entries on all sorts of topics about the English language. It also has some great little snippets of trivia tucked amongst the pages. When Mrs S was reading the page entry about alphabetical order she read this snippet:

The order of the alphabet from the most used letter to the least used letter would be: e a r i o t n s l c u d p m h g b f y w k v x z j q

[Concise Oxford Dictionary 11th edition 2004]

She share this with our class and suggested that we could collect some data by counting letters and see if we got the same result. We decided to count the number of each letter used in three sentences from a book that we were reading. We found our books and started tallying. After we had totalled our tallies we each created a bar graph. Each bar graph showed the order to be slightly different.

The next step was to combine our data into one graph. We did this by entering our data into a Google doc form and we saw the collected data on a bar graph that the google doc spreadsheet created. Take a look at our combined results (click on the image to see it full size).

 The letter ‘e’ was definitely the most used letter and this was followed by the letters – t, a, i, o, n, h, s, r, d, l, m, c, g, u, f, w, p, k, y, b, q, v, j, x, z. Our data was showing a different order to the one in the book.

We now hope that you will help us collect even more data to see if our graph changes and whether we can get the same result as the list in the book Mrs S shared. To help us out you will need to tally the number of each letter in three sentences from a book you are reading and add the data to our Google Doc form.

Follow the link to see the bar graph of our results.

Please leave a comment to tell us about some data you may have collected or make a suggestion about why our results may be different to those in the book.

Word of the Week – last one for Term 1 and Other Things

April 26, 2013 · 20 Comments · Books and Reading, Finding Out, Mrs S, Spelling

Stopped WatchTerm 1 has finished and the time went so quickly. We have been working very hard researching, writing, calculating, keeping fit, reading and thinking. We have explored the writing genre of exposition and written several different pieces of writing that fit into this genre. We have explored graphing and are gradually creating a collection of graphs about our class.

During the last week of term Mrs S shared an interesting book with us. She had borrowed it from the State Library. The title of the book was Tick-Tock and it is part of a series called Wonderwise. When you look at the cover you might think that this is a book just for younger readers but there is plenty to think about within it’s covers. We had the quick tour of time from heartbeats to seconds to minutes and right up to centuries.Time is measured in many different ways.

Did you know that in ten heartbeats a snail could crawl the length your hand?

Did you know that in fifteen seconds a  fly can beat its wings about five hundred times? We tried flapping our arms for fifteen seconds. Try it yourself and let us know how many flaps you counted. A side benefit of this time trial was to get our hearts beating faster!

Our word of the week was also related to time. Do you arrange anything in chronological order? Take a look at our Prezi containing the spelling, vocabulary and grammatical observations we made about the word chronological.

Please leave us a comment letting us know whether you tried flapping your arms for fifteen seconds. Have you arranged anything into chronological order? Just tell us an interesting fact about measuring time.

Word of the Week Number 3 for Term 1 2013

March 23, 2013 · 4 Comments · Uncategorized

We are more than half way through Term 1 and Easter is coming up next week. We have been working hard in our classroom looking at graphing, rounding off and other maths. We have been talking about the different genres that we can use to sort the books we read into categories and Mrs S showed us the page on our blog where we can quickly add a review about a book that we have read.

The word we looked closely at this week was chosen because of our graphing work. There is a great video that some of the class watched and it is all about bar graphs. The x-axis of a bar graph is horizontal – our word of the week. We used this word to show our spelling and grammatical knowledge by making as many observations about the word as we could in our books. Watch our Animoto to see some of the things we listed.

Did we miss any? What else could we have noticed? Please add a comment to this post adding some more information or using horizontal in an interesting sentence that shows you understand it’s meaning.

Word of the Week Number 2 for Term 1 2013

March 4, 2013 · 1 Comment · Spelling

Our Word of the Week for last week was frequency.

We are exploring displaying data collected from surveys as part of our Maths. Last week we looked at recording data in a frequency table.

Take a look at our Prezi to see the spelling and grammar observations we made about the word frequency. Remember that you can click on the full screen button at the bottom right of the Prezi to make it easier to read.

Please leave a comment with any more observations you would like to add. We didn’t mention them all.

Last week in out class we had a discussion about the symbols we use in Mathematics. They are a little bit like a secret language and you have to know their meaning for mathematics to make sense. We listed quite a few on our whiteboard during our talk. It was interesting to see how some of them were written.

A symbol is a picture or image that is used instead of words.

Take a look at our Padlet wall. Add a sticky note to the wall to tell us about some maths symbols. You can add a link to a website or add a link to a picture you may have found.

Why do you think that mathematicians might like using symbols? Please leave a comment with your thoughts.

Word of the Week Number 1 for Term 1 2013

February 23, 2013 · 5 Comments · Maths

Here is our first word of the week for this year. We will be exploring lots of words during the year and have started out by looking at maths words.

There are many words we hear that have a special meaning when used during Mathematics. We could almost say there is a Maths Language just like there are other languages around the world such as Japanese, French, German and English.

The first word we have focused on is ADDEND. Please watch our Animoto to see all the spelling and vocabulary observations we made when talking about this special maths word.

Please leave a comment and share an observation of your own about the word ADDEND. Can you make some spelling connections to other words?

Thinking about Learning

February 16, 2013 · 9 Comments · In The Classroom

Last week during our time with Mrs S we looked at some posters about The Parts of a Reader, Mathematician and a Writer. We used these as the starting point to create our Word of the Week book covers with The parts of a Speller on them. We can use this to remind us of all the things we do that help us with our spelling. There are some interesting suggestions in this blog post that might help us with our learning of  new words.

While Mrs S was doing some reading about education and learning she wondered whether there was another poster we could create. Could we make one for The Parts of a Learner? She wondered what do we do when we learn. How do we use the different parts of our body to help us learn a new idea or concept? What do we need to think about to become a better learner?

Mrs S found this video, by another teacher who blogs, where she asked some of her students to talk about learning.

How do you learn? What helps you to learn? Please leave a comment to start a great conversation about learning.

A New Year, A New Class and a Continuing Blog Journey

February 8, 2013 · 2 Comments · In The Classroom, Mrs S, Spelling

The new school year has just started here in Tasmania. We have been back at school for four days. Our books are sorted and many of the class are busy helping cover their books ready to fill them with work.

We have shared stories about our holidays, started exploring some interesting mathematical challenges and created some great artwork. Mrs S purchased some posters online that listed the parts of a reader, mathematician and a writer. We used these as inspiration for the cover of our Word of the Week books. We brainstormed ideas for the parts of a speller and Mrs S created some labels based on our suggestions. We drew ourselves on the cover of our books and added the labels to inspire us during the year. Take a look at some of them in our Animoto below.

 

How would you describe the parts of a speller? What do we use our mind, eyes, ears, mouth and hands for when we spell? What are the tools of a speller? Please leave us a comment letting us know.

Exploring Fibonacci patterns

December 17, 2012 · 4 Comments · Finding Out, Maths

Sunflower in our school herb garden.

Mrs S found some great picture books to share with us last week. We have just finished a science unit all about plants. Mrs S first shared the book called Growing Patterns by Sarah Campbell. It has some fabulous photographs of flowers and it introduced us to a very special set of numbers.

The next day she read us the book  called Blockhead by Joseph D’Agnese. It told us about the life of Leonardo of Pisa and his fascination for numbers. In the book we found out about Roman Numerals and also our Hindu-Arabic numerals and a very special number pattern that is now known as the Fibonacci Sequence.

Did you know that Leonardo of Pisa was one of the mathematicians responsible for our ancestors changing from the Roman Numeral number system to the Hindu-Arabic number system?

We explored the first 25 Fibonacci numbers and found some very interesting facts. Did you know that the fifth Fibonacci number is five? The 12th Fibonacci number is 144 which can be made by multiplying 12 by 12. There is also a great pattern of odd and even numbers. Do you know what it might be?

Here some very interesting Youtube videos that share things about the Fibonacci Sequence.

Please leave a comment on this post to tell us something interesting that you know about these very special numbers.

Creating Christmas Trees

December 14, 2012 · No Comments · Art, Maths

As part of our Maths unit on 3D shapes we found a pattern for a cardboard Christmas tree on the Makedo website. We scaled down the templates to create our trees. Mrs S halved the measurements to make the white class tree. We joined this one together using the Makedo joiners.

For our own trees we needed to quarter the measurements before Mrs S created a set of templates for us to trace around. All this quartering gave us lots of practise at dividing numbers by 4. We also converted the mm measurements to cm measurements as part of our measurement maths work. We also had to do some rounding of our numbers.

We needed to collect lots of cardboard, mainly cereal boxes, to cut out all of our pieces. For our small trees we used split pins to join all the pieces together. Unfortunately we ran out of boxes so our small trees only have three layers. We think they still look good. What do you think?

Mrs S found some great Zentangle instructions for Christmas lights and some of us have drawn these on the layers of our trees.

What 3D shape are the layers of our tree made with? How many edges, vertices and faces does this shape have? How many split pins do you think we used altogether? Please leave a comment letting us know what you think.
