My next solution got rid of all of the conditional ‘If Then’ statements and utilised lists, instead. I wouldn’t expect any of the children to come up with this solution but it has certainly been an interesting exercise for me as I explore Scratch, as well!
In the class, we are starting to learn some programming. The language we are using is called Scratch.
Scratch is a free visual programming language. It is aimed at young people, mainly 8 years old and up, with a purpose of helping them learn programming.
Scratch is available online and it’s easy to create an account if you’d like to use it outside of school. Just follow this link.
The first challenge we are working on is below!
Get Scratch to draw a shape in a random location on the screen:
The shape must have a random number of sides between three and eight
If the shape is a triangle, it should be RED
If the shape is a square it should be ORANGE
If the shape is a pentagon it should be YELLOW
If the shape is a hexagon it should be GREEN
If the shape is a heptagon it should be BLUE
If the shape is an octagon it should be PURPLE
Repeat the above forever.
The video, below, shows what we are hoping to achieve.
A solution for this challenge may look something like this:
While the code took me ten minutes to write, it will be a significant task for the children which gives some terrific real world challenges for them to explore. We will build on ideas and concepts in small stages working up to a complete solution.
The ideas and concepts include:
Positive and negative integers
Coordinates on an x and y axis
Iteration (Looping) – Count controlled and continuous
Of course, along the way, the children discover different things that interest them which they add to their code which adds to the fun 🙂
There’s a wonderful TED video, below, which talks about teaching kids to code with Scratch.
