Translation, Rotation and Reflection

On Monday during Maths we discussed of some words we meet when working with tasks from the transformation and location section of the Measurement and Geometry strand of our Maths curriculum.

When working with a 2 dimensional shape we can rotate, reflect and translate the shape.

To translate a shape is to move or slide it up and down or from side to side without changing the shape in any other way.

To reflect a shape is to flip the shape over a mirror line.

To rotate a shape is to turn it around a given point. The distance from the centre to any point on the shape stays the same.

We worked in pairs, using Scratch, to create a program that demonstrated our understanding of one of these mathematical terms. Mrs S has added our work to a Scratch studio and embedded some below.

Have we demonstrated our understanding of translation, rotation and reflection? How else could we share our knowledge about transforming shapes? Please leave comment sharing your thoughts.

Our Dot Day Creations

Here are some of our Dot Day creations.

Rohan made a mark by creating a Scratch program. Click the green flag to watch his bouncing dots. Click the red octagon to stop the show.

We created a display outside our room with our blotting paper dots and our concentric circle patterns. We added a QR code directing those with a mobile device to our class blog post about Dot Day.

Cascading Dots

We explored creating patterns using concentric circles. Each level out from the centre contained an extra element of our pattern.

What do you think of our dots? Have you used Scratch to create? How have you made your mark and where has it taken you? Please leave a comment sharing your thoughts.

 

International Dot Day

September 15th is the date when Peter Reynolds published his book called The Dot. It is the story of a little girl called Vashti and her journey towards creativity.

In 2009 a group of teachers began to use this date to celebrate International Dot Day. They shared their ideas over social media and more and more classes around the world have used this day to explore the themes of bravery, creativity and self-expression as Vashti did in the story of her dots.

Explore our ThingLink to hear Vashti’s story, find out who has been creating celebridots and about some artists who use dots in their work. Hover over the image and follow the links attached to it.

While the Grade 5’s have been finishing up their learning at the pool the Grade 6’s delved into creating some dots. We used blotting paper and water soluble textas to create some of our dots. We made printed patterns with cotton reels and circular felt stampers. We are working on some patterned dots and we are working on some digital dot artworks. Once our work is finished we will share in another blog post.

Below is a video of a celebridot in creation. Watch as Renee Kurilla, a children’s book illustrator, creates an image that is similar to her celebridot.

Swimming and Water Safety Time and IT Helpers

Our Grade 5 classmates are spending some time each day at the pool. They are participating in our yearly Swimming and Water Safety program for students in grades 3-5. They are all using the time to become better swimmers by practising their strokes and to learn survival and safety techniques.

On Tuesday, before the Grade 5’s headed off to pool,  all of the class worked hard  by becoming IT buddies for the children from Prep F or the children from Prep/1 G. They helped the students in these classes to do some drawings using ArtRage. This computer program is one of Mrs S’s favourites.

Before using ArtRage both classes listened while Mrs S read a story. Prep F listened to a story called Russell the Sheep by Rob Scotton and Prep/1 G listened to Diary of a Wombat by Jackie French. Then each class drew their favourite part of the story with some great technical help from the Grade 6 helpers. Everyone practised using layers to separate out parts of their drawings.

Adding layers in ArtRage can be very useful.

While our Grade 5’s were enjoying themselves at the pool the Grade 6’s were hard at work back at school. They were all challenged to create a presentation of the drawings created by the younger classes. Mrs S did not tell them which computer program to use and many of the class used two or even three different programs while creating their presentations. They found out that it can be a very repetitive task as they added pictures, resized them, worked on transitions and timings, and tried out different layout ideas.

Below are some of the finished presentations. Not everyone finished in the timeframe we had. An afternoon was just not long enough!
