This help sheet is designed for students studying A-Level Computer Science and includes details about the common binary numbers that will occur when using 4 bit unsigned binary to represent fractional/decimal numbers.

This resource is aimed at students studying A-Level Computer Science and 20 questions on converting a given Fixed Point Binary number in Denary and a further 20 questions converting a given Denary number into a Fixed Point Binary number. It also includes the associated answer sheet.

This resource is aimed at students studying A-Level Computer Science and contains 20 subtraction calculation questions that must be completed using Two's Complement Binary and the associated answer document.

This resource is aimed at students studying A-Level Computer Science and contains 22 unsigned binary addition calculation questions and the associated answer document.

This resource is aimed at students studying A-Level Computer Science and contains 56 conversion questions between Two's Complement Binary & Denary and between Denary &Two's Complement Binary. It also includes the associated answer document.

This resource is aimed at students studying A-Level Computer Science and contains 20 binary multiplication calculations and associated answer document.

This is a resource aimed to be used with students in KS3 to test their ability to convert to and from Binary and Denary/Decimal numbers. Section 1 - Binary to Denary/Decimal The first section of the worksheet starts with getting students to convert an 8 bit binary number into its equivalent denary value. After they have complete these there are a couple of extension questions that get them to try and expand their understanding by finding out what the next column headings are for the binary numbers that come with 10 bits and then 12 bits. Section 2 - Denary/Decimal to Binary Once students have been shown the way to convert from Denary/Decimal into binary there are a series of conversions that they must carry out to create the binary string from the given denary/decimal numbers. If they finish the main section, there are 2 small extension sections that get students to try and develop their conversion skills by converting number that require 10+ bits. There is also one questions that requires them to use 16 bits. I have also included the answer sheet for both the conversions so you can go through the answers with the students in class.

The attached resources is designed to help you monitor and track students’ progress through the COMP4 project. There are 7 sections in the overall project, each of these sections is given its own spreadsheet worksheet. The 7 sections for each tab are: Analysis, Design, Technical Solution, System Testing, System Maintenance, User Manual, Appraisal Each cell is formatted using conditional formatting to give you a quick visual representation of how well the student in progressing through their project: - If you enter Y the cell will go Green (Section Complete) - If you enter P the cell will go Yellow (Section Partly Complete) - If you enter N the cell will go Red (Section Not Attempted). Based on the amount of sections completed you can then award the student a suitable mark for their work. On the final worksheet there is a summary of the students grades across all 7 sections and then a predicted grade based on the grade boundaries from the AQA past grade boundaries for COMP4 coursework. The content has been created from the Project Log PDF supplied by AQA.

This is a collection of 2 resources designed to aid in the tracking and monitoring of students who are completing the AQA GCSE Computer Science (4512) Specification. In Component 2 of the specification students are tested on a range of different theoretical elements relating to Computer Science. With this checklist and tracker you will be able to keep track of how much progress each individual student has made across the course content. The checklist can be given to students to fill in, they aim should be to fill in the Student column with either a Y, a P or an N. - If they have answered Y, this means they feel confident with this point on the specification. - If they have answered P, this means they understand some of the content for this point of the specification. - If they have answered N, this means that they do not understand any of the content for this point of the specification. There is also a column available for the teacher to make a mark, again, either a Y, P or N is useful here. This is useful for formattive assessment of how well you think the student is doing with the theoretical content. After you have collected the data from the students you can enter this data in the tracker (this is meant to be a working document, so the checklist in student’s folders gets updated regularly as does the tracker.) The student’s names and GCSE target grades should be entered at the top of the spreadsheet. Then for every point on the specification for every student, you need to enter either y, p or n (lowercase). Once this is done, you will find that each section will show a percentage of how much of the specification has been completed for that student and at the top of the page, you should see a working grade based on how much of the content they have covered (this will only show their overall progress against the whole specification).

This resource is a worksheet designed to help students learn the different units of measurement of Binary numbers. They will start off small learning the correct term for 1, 4 and 8 Bits of data and then start moving towards the larger denominations for Kilo, Mega, Giga-bytes etc. At the bottom of the worksheet there is a couple of extension questions aimed at improving the students knowledge of data representation by trying to find some real life applications of these terms. I have also included the answer sheet. PLEASE NOTE: This version of the worksheet is designed to teach students the correct definitions for variations of 1000. There is also a different worksheet for the 1024 variations that will teach students the correct definitions for Kibi/Mebi/Gibi-bytes.
