In Scratch advanced this week we learned some cool math formulas that are really handy for doing interesting stuff in programming.
The things we went through!
- We revised X and Y and reminded ourselves how it works
- We drew a house using X and Y
- We learnt about circles and radius
- We learnt about the math formulas Sin and Cos and how they can be used to get X and Y positions on a circle
- We learnt about Custom Blocks in Scratch
- We wrote our own Custom Block that could draw a shape of any size and number of sides, using Sin and Cos to figure out the points!
- We used that Custom block to make lots of neat patterns (some by accident!)
The notes are attached in PDF and if you follow them you will have a project ready to go for this Saturday – we are going to take that custom block and do some really cool things with it. Don’t worry if you don’t have the time to do it or can’t follow the notes though – we’ll have this shared out so you can just take off where we finished!
Twister Notes Week1

This season at CoderDojo Athenry, the advanced groups are all starting with taster sessions of the various topics we will cover.
Here are the notes:
- How to Connect to Each Other’s Servers
- Creating our First ScriptCraft Mods
Coming up next week: in introduction to Raspberry Pi and Electronics
We had a great crowd for our first session today in Scratch beginners. A big welcome to all our new Ninja’s and of course a special welcome back to our younger Ninja’s from last year, who are still with us.I forgot to take some pictures of the big crowd but we had up on 100 Ninja’s signed in to our Scratch Beginners session alone today.
Thank you all for coming and for your patience while we got everyone sorted out with downloading Scratch 2.
We started today with our first game, as well as learning how to write commands to move our sprites, we took a brief look at the interface for Scratch 2.
We also took a first look at some fundamental concepts that we will be using throughout the year. Today we looked at the X and Y axis as well as the number of degrees in a circle.
Here are the presentation slides from the day, in PDF format: CDA-S5-Week_01-FirstGame.pdf
I hope you all enjoyed today and hope to see you all again over the next couple of weeks!
CoderDojo Athenry is running every Saturday from 12:00 to 2pm in Gairmscoil Mhuire school (“The Tech”), with regular sessions starting on 26 Sept 2015. New members are always welcome – just come along and fill out a registration form.

For those not starting Scratch Beginners or Advanced, we will have taster sessions of the other topics each week for the first 4 weeks.
A lot of you had a chance to see the Minecraft Project that some of our Ninjas worked on over the Summer weeks in Athenry Castle a couple of weeks ago.
As part of heritage week, Ruaidhrí, Eiblinn, Eoin, Darragh and Luke built a 13th century replica of Athenry Castle in Minecraft.
I promised a link to download the World and the Mods used, so here is a link to Dropbox where you will find all the files.
See you all Saturday! (September 19th)
