This contains six python challenges, with accompanying solutions. Each activity is broken down into a few success criteria, with extensions for higher level skill use.

All the help sheets below were created inline with the specification for OCR J276 ‘Computational thinking, algorithms and programming’ and ‘Programming Project’ sections of the course. I created these for my own Year 10 students and they have found them very useful, when introducing sections of Python programming theory, Flowcharts and Pseudocode. I use these in lessons to drive independence and as a reference for the pupils whilst programming so they are not constantly looking things up on the internet. They find the sheet with the topic on and the key information is there. In my classroom I have arranged a display using folders to hold the sheets so the students can walk up and grab the sheet that best suits their needs at the time. Hope they help!

Recently remade for J277! I have created revision cards for all topics in the OCR Computer Science GCSE (J277). These are used by my current Year 11 Cohort, they have found them quite effective as support tools in lessons and revision at home. I allow students to use them whilst answering question in lesson so that they are focusing on exam techniques whilst absorbing the subject knowledge too. I have created a revision wall by printing each card in A3 and arranging it on the wall. Students can consult the wall if they are stuck. All the cards have been designed to be printed double sided on the short edge, This is so that the topic name is on the back. All cards are using the ‘OpenDyslexic’ font, this can be seen on the PDF’s. Formatting may differ on the publisher document if you do not have the font installed. This pack consists of the original publisher file as well as a PDF of all the cards too. I have also created a PDF of each set of cards that represent each separate paper of the OCR course. Enjoy! UPDATE# I have added the Pseudocode Programming Techniques page, to match up with the Question Cards

I have created Recap Grids for all topics in the OCR Computer Science GCSE (J277). These were used by my Year 11 Cohort, they have found them quite effective as recap starters at the beginning of lessons and revision at home. They work great for testing students knowledge after delivering a topic as well . All the Recap have been designed to be displayed on an interactive whiteboard or on a mobile phone/tablet. All cards are using the ‘OpenDyslexic’ font. Formatting may differ on the the PowerPoint if you do not have the font installed. This pack consists of the original PowerPoint file with Macros programmed to ease the users navigation of the content. Enjoy!

For this game you will need to print the board, Set of Questions (Paper 1 or Paper 2) and a rule card. The instructions are set out on the rule card. The rules have been created to involve questioning as well as playing the game. I have included the original files and a PDF version. The main file is created using the ‘OpenDyslexic’ font formatting may change if this font is not installed. Enjoy!

This is a Lesson for teaching Searching Algorithms, Complete with differentiated worksheets. The PowerPoint is self explanatory and has corresponding slides for the task sheets. The lesson is designed to be 2 hours in length. The lesson is designed to be very interactive for the students. I have bought playing cards from Wilkinsons (£5 for enough for 30 students), using these the students can physically sort the numbers using the sorting algorithms throughout the lesson. Later in the lesson when the students are Searching the letters and words I use sticky notes on the playing cards for differentiation of LA pupils. The plenary assumes your students planners have green, amber and red cards in them. If they do not you can either print and laminate your own or use hands up. Enjoy!

This is designed as a 2 hour year 10 Lesson the first of my lessons on the Data Representation section of the J276/J277 course. This lesson is completely in line with the J276/J277 Specification. In this lesson the idea of Binary is introduced, converting binary to denary and the reverse of this. After this Character representation is introduced, Character sets, ASCII and UNICODE. The PowerPoint is designed to be using the ‘OpenDyslexic’ font, I have included a pdf of the lesson to that the layout can be seen if your school does not us this font. Enjoy.

I have created a PowerPoint with 65 different programming challenges that are ordered by difficulty. On each slide I have a meter that shows how difficult the question is and what skills are required to solve the problem. The Powerpoint can be used in one of two ways: Firstly the PowerPoint can be used as a means of delivering programming challenges to students based on skills and difficulty. Using the Random Challenge Generator page you can pick whether you give the students or student an Easy, Medium or Hard challenge. I have found this particularly useful for differentiation in a mixed ability class when practising programming. The Second use is the game board. Using this slide the students can progress through 18 fixed challenges that are designed to take the students from very basic skill to getting them onto larger programming challenges( This will encompass more that enough time required for OCR J277) . The PowerPoint is designed in ‘OpenDyslexic’ Font so install this if there is an issue with formatting. I will later add solutions for all challenges. I will later update the PowerPoint to add the functionality for students to check their answers. Enjoy!

This set of resources is around building Python skills. It has been designed for KS4 Computer Science students, with OCR J276/J277 in mind. No prior Python knowledge is required from students, as the resources are aimed at complete novices. Enclosed is 29 hours of lessons. Within this there are assessments designed to test and challenge the students. Lesson have been numbers with my suggested order. The following skills are covered: Inputs and Outputs Variables Data types and Casting Maths String Manipulation Conditional statements Iteration Arrays Procedures and Functions Defensive program design Debugging Flowcharts Pseudocode This lesson is designed in ‘OpenDyslexic’ font, if you do not have this font installed the formatting of the lesson may be out. On the side of each page is a volume meter, this can be used for behaviour management to show students how loud they are and where their volume should be. Enjoy!

This is Designed as a 1 hour theory lesson that is towards the end of my Python Skills Lessons series. The lesson is an introduction to the use of external files, specifically csv’s. This will teach the students basic reading and writing skills in csv’s. This lesson is designed in ‘OpenDyslexic’ font, if you do not have this font installed the formatting of the lesson may be out. On the side of each page is a volume meter, this can be used for behaviour management to show students how loud they are and where their volume should be. Enjoy, the rest of the series will be uploaded soon.

Instructional Slides and Game Sheets are inside. Simply print the game sheets, two per group. If possible laminate the sheets for reuse, with whiteboard pens. Make sure sheets are folded before playing, We do not like cheating! Instructions should be straight forward. Enjoy!

This is a resource I made for my Y11’s to practise all the different conversions. Hope it Helps!

The resources in this pack contain a information sheets perfectly for printing double sided and using by students for referencing or independent revision. There is one sheet for each topic in the A451 specification. All sheets use 'OpenDyslexic' font so are friendly for dyslexic students.

This is a Lesson for teaching Logic Gates, Complete with differentiated worksheets. The PowerPoint is self explanatory and has corresponding slides for the task sheets. The plenary assumes your students planners have green, amber and red cards in them. If they do not you can either print and laminate your own or use hands up.

This lesson is designed to be 1 hour in length. In the lesson the students will be introduced to image representation in a computer. They will understand the two main different types of images and what affects quality and size of an image. This lesson was designed to use the ‘OpenDyslexic’. I have attached a pdf in case your school does not use this font so you can see the presentation. Enjoy.

This lesson is designed to be 2 hour in length. In the lesson the students will be introduced to Computational thinking and all of its elements. The students will then look at both understanding and writing algorithms. This lesson is based off the students knowing Pseudocode and flowchart design. This lesson was designed to use the ‘OpenDyslexic’. I have attached a pdf in case your school does not use this font so you can see the presentation. Enjoy.
