Binary Worksheet Generator

(0)
Unlimited worksheet generator for work on binary code. This generator can very quickly create the following randomised worksheets for students: • Decimal to Binary (2-8 bit length) • Binary to Decimal (2-8 bit length) • Binary Addition (2-8 bit length) • Binary Shift (2-8 bit length) Simply by selecting the bit length you can generate a full worksheet in PDF format ready for printing or sharing with a single button click. All worksheets can easily be customised if you wish. This worksheet generator can produce over a undecillion different worksheets - that’s a ‘1’ with 36 zeros after it! Easily enough to keep students busy. The difficulty of the worksheets can easily be changed by altering the bit length, allowing for differentiation/levelling. ANSWER SHEETS ARE INCLUDED WITH EVERY WORKSHEET FOR QUICK, SIMPLE MARKING!
Algorithm Demonstration

Algorithm Demonstration

(0)
A simple but effective introduction to the concept of algorithms. Students are shown a series of random numbers one at a time, and have to tell the teacher which is the largest number. They don't know the range, and they don't know the quantity of numbers. However, all students can do it, by quickly creating a set of simple rules to follow in their head - an algorithm. Without realising it they create a set of instructions to follow, they create a variable, and they carry out comparison tests. They use input, and output, and effectively demonstrate all of the attributes of a simple algorithm. This demonstration can then be used to introduce these ideas, and the whole concept of computational thinking.
Anti Gravity Connect 4 - Class Quiz

Anti Gravity Connect 4 - Class Quiz

(0)
I use this simple tool as a way of spicing up class quizzes. The class is divided into two teams - red and blue. One representative from each team comes up to the board. A third, independent student can be the quizmaster, or the teacher can fill this role. Each team is asked a question. If they get the question right then they can add one of their team's coloured tokens to the board by simply clicking where they would like to put it. No gravity with this version of Connect 4 - they simply need to make a row of four coloured counters in any direction. (Make it easier by limiting it to three, or make it much more interesting by making them try to make a row of 5 or even 6 counters.) The quizmaster simply needs to click the button in the top right corner to select which colour team is able to add a token to the board. Click a coloured token twice to reset its colour to white, or use the reset button at the top left to reset the whole board. Any questions, comments or suggestions welcome.

A selection of real logos, compared with re-created logos made entirely in PowerPoint using the Shapes tool. This was to demonstrate to classes how dynamic and versatile the shapes tool can be for creating logos and images.
