KS3 Computer Science - Binary/Denary Conversion - Worksheet
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.
