Hour of Code!

This week is the beginning of the International Week of Computer Science, when tens of millions of students from over 180 countries participate in “Hour of Code”. This is a great activity to introduce students to computer science in a fun, easy and accessible way. Here are some resources to introduce coding in your classroom:

Make a Flappy Game - a ‘drag and drop’ method to create your own version of the popular flappy bird game.

This week we have about 30 students from Year 7 to 9 attending school, while the rest participate in the end of year “Great Hawkesdale Bike Ride”. They enjoyed creating their own Flappy Bird and Angry Bird Games and then constructing Christmas scenes in Minecraft. Which games did you create, which was your favourite and why?

Year 6 to 7 Orientation Day!

Congratulations on completing Year 6 and welcome to Hawkesdale P12 College for Year 7. This blog is where I will post some of your Maths classes for next year. If you scroll back through the posts you can see some of the work we have been doing this year in Year 7 Maths.

TASK 1: Please complete this survey.

TASK 2: Create a Christmas advent calendar using PowerPoint. Follow the steps below:

  1. Open Powerpoint and insert a 5 x 5 table.
  2. Add Christmas themed clip-art to each cell of the table.
  3. Cover each image with a shape, using “Insert” > “Shape”.
  4. Number the shapes in each cell from 1 to 25.
  5. Add animations, so that when you click on the shape, it disappears and the “treasure” is revealed.

TASK 3: Hour of Code (see post above).

If you have finished, you may like to create a Christmas card for your friends or family. When you have finished you may like to try some of these games:

 

A selection of maths videos from YouTube

“Life of Pi” is one of my favourite movies, with a beautiful soundtrack and amazing cinematography. I was trying to find the video clip of Pi in the classroom, when he is tired of being teased for being called “Piscene” (or Pissing) and fills the blackboard with the irrational number ‘pi’. Can you post in the comments below if you can find that clip from the movie? Some other good maths clips linked below:

What are the Chances?

You will be familiar with hearing discussions about probability in terms of words, if not quantities – “It isn’t likely to rain on the washing today”, “The chances of winning the lotto are very small” “It is equally likely that the other team will win”. For the remainder of this term we are going to use numerical representations of probability, including tree diagrams, two-way tables and Venn diagrams.

Windows Apps for Maths

Our Year 7 and 8 classes received Microsoft Windows tablets at the beginning of last term, as part of a DEECD trial, “Inking your Thinking”. The students have enjoyed using these devices to access Mathletics, as well as playing the “2048″ game in free time at the end of a lesson. However, there are some more good Windows apps that I would like each student to download onto their devices.

How many triangles?

Learning Intention: Students will understand how to calculate the area of a triangle, using the rule Area = 1/2 x base x height.

Success Criteria: Students will draw and label at least four different triangles of the same area.

How many different triangles can you draw with an area of 120 cm sq? Use graph paper, where 1 cm ~ 10 cm and label the base and the height, showing any right angles.

Graphs and Data

Last week you were working on a poster showing the results of a class survey in table and graphical form. This data is just a small sample of the school and state data. When governments and businesses want to plan for the future they need to know information about the whole population – for example, where roads, schools and hospitals need to be built. This information is obtained using a census. The national census is conducted every four years, when the Australian Bureau of Statistics asks every household to complete a survey.

Some of the data obtained in the 2011 census is recorded here. Choose one of the categories that you are interested in and create a graph of the data using “Create-A-Graph”. Email your graph to me and a copy to yourself.

Equivalent fractions with a Fraction Wall

This week we will continue making our fraction wall and learning how to calculate equivalent fractions. Using your fraction wall, find equivalent fractions for the following: 1/2 (one half); 1/3 (one third); 1/4 (one quarter) 2/3 (two thirds) and 3/4 (three quarters). What are some other equivalent fractions that are “off the scale” – using fifteenths, sixteenths, twentieths or hundredths?

To add or subtract fractions we need to make sure they have the same denominator (bottom number). We can convert fractions so that they have the same denominator by multiplying both the numerator and the denominator by the same number. This interactive from NLVM helps to compare fractions and create fractions with the same denominator.

Here are some links to sites for learning more about fractions:

Apps for Year 7 Maths – Number


Image source – screenshot from the “Motion Maths” app, in which the user must tilt the device to “bounce” the ball at a specific point along a number line.

This term we are starting with the characteristics of whole numbers and then fractions and decimals, including the following concepts:
– positive and negative integers
– square numbers and square roots
– factors and multiples
– prime and composite numbers
– prime factor trees

There are several apps that may assist you or your child to understand these concepts. The following apps are all available on IOS devices (iPhones, iPods and iPads) and some may be available on android devices.

- Zoom (place value – ordering whole numbers)
- Wings (greater than and less than, multiplication)
- Motion Maths (fractions)
- Wishball (place value, addition and subtraction)
- Fraction Factory (fractions, decimals and percentages)
- Number Line (fractions, decimals and percentages)
