In this project, based on Flappy Birds, the player has to navigate an octopus through waves of hungry sharks.
There are so many really great sites offering Scratch Project ideas. However, many tend to be like recipes - follow the instructions and you’ll create a cake. The problem I find is that the students almost mechanically enter code and create “delicious cakes”, but without learning an awful lot about Scratch.
My goal is to get students to create a fun project, whilst at the same time learn how the instructions work and fit together. To this end, I use the following approach:
break the project down into manageable chunks
present students with an algorithm for each chunk
provide students with the instructions for each algorithm, but jumbled up
In this way, students learn about algorithms (a VERY important part of coding), and have to understand the instructions in order to sequence them to correctly match the algorithm.
The lessons comprise:
a PowerPoint with introductory slides, together with the project instructions
a Word document with the PowerPoint instruction slides printed 2 to a page as a handout for students to follow
accompanying fully-working Scratch project files for teachers that match each chunk of the project
Let me know if you have any questions or suggestions, and a BIG BIG thanks for looking (as a full time practicing teacher, I KNOW how time consuming this process can be).
ALL my postings are FULLY “classroom-tested” - before I publish, my lessons are tested by both myself and colleagues, rigorously evaluated and discussed, and continually updated to maximise their effectiveness. But there is always the possibility of error and room for improvement, so do please provide constructive feedback.

The ever expanding CodeClub first promoted Scratch, and I loved it – creating and successfully delivering a range of lessons for Junior students.
Code Club is now promoting Blender and I think I love it even more!
I’ve created and delivered a series of lessons for Junior students this year, and the response was overwhelming. Students loved learning about 3D graphics and went on to produce some amazing creations of their own. While I thought it might be too advanced, students as young as 8 have grasped and loved using it.
3D GRAPHICS REALLY IS A USEFUL SKILL FOR THE DIGITAL FUTURE.
The lessons assume absolutely no knowledge and build up in a gradual way
Lessons 1-2 (FREE)
What is Blender
The Blender interface
Navigating the 3D view port
Lessons 3-5
Transforming objects
Creating, selecting and duplicating objects
Project: create a snowman
Lessons 6-9
Rendering, colours and lighting
Editing objects
Project: create a donut
Lessons 10-13
3D Text
Box modelling - extruding, loop cuts, insets, bevels
Project: create a Treasure Chest
Lessons 14-15

Animations using Rigid Bodies
Each lesson is delivered via an animated PowerPoint with an accompanying Workbook, and follows a similar format:
A short video to inspire (embedded in the PowerPoint)
Explanations about any new concepts and skills
A demo of what will be covered (Blender demo files included)
Working together trying out these new concepts and skills (Workbook and Blender exercise files are provided)
Free exploration
A project bringing it all together (a finished Blender file is provided)

In this project, students create a toy bear, using sprites to simulate “touch pads” -making the bear smile, blink, change colour, etc. Enhancements include using the keyboard instead of sprites, and adding sound.
There are many sites offering Scratch Projects. However, many tend to be like recipes - students almost mechanically enter code and create “delicious cakes”, without learning a lot about Scratch.
My goal is to get students to create a fun project, and at the same time learn how the instructions work and fit together. I use the following approach:
- break the project into manageable chunks
- present “pseudo-code” for each chunk
- provide the Scratch commands to implement the pseudo-code, but jumbled up
In this way, students learn about pseudo-code (an important part of coding), and have to understand the Scratch instructions in order to sequence them correctly to match the pseudo-code.
The lessons comprise:
1. a PowerPoint with instructions
2. a Word document with the instruction slides printed 2 to a page as a handout
3. accompanying Scratch files for teachers that match each stage of the project

How often have your students (and often, colleagues) struggled to find their files?
File Management is so critical to managing digital content, yet students (and adults) know so little about this.
The course is delivered in 3 x 60-minute lessons, using stimulating PowerPoint presentations with embedded videos, and includes worksheets to accompany the lesson, a self evaluation document, plus a Kahoot quiz.
storage devices
digital files
opening and saving files from within applications like Word

Having seen so, so many worksheets on punctuation, I finally decided to create this 25 page pack - based on cherry picking and then adapting the best ideas from countless text books and worksheets.
It covers a range of the punctuation used up to Year 6 and provides succinct definitions and plenty of varied practice for each topic.
Mastering punctuation is essentially practice, practice, practice… we all have able Year 6 children who simply forget basic capital letters and full stops (periods)! So these worksheets, a real labor of love, are designed to provide this essential practice.

I introduce students to programming through Scratch, and then extend this into the world of text based coding through Python and Python Turtle.
The lessons use Trinket as a simple interface for entering and running Python code - no downloads required.
The students are introduced to Python coding in the context of creating amazing patterns. In so doing, they become familiar with the commands and the syntax, and learn to debug errors they will inevitably have made. There is enough material for approx. 4 one-hour sessions, and of course, once students get started, they can easily develop their own ideas.
I’ve delivered these lessons to Year 5/6 students, and they have absolutely loved it.
The lessons are delivered through a fully animated PowerPoint with explanatory slides and embedded videos (can be extracted if required). In addition, there is a workbook of activities.
