Logical Number Reasoning Activity

This activity combines computing and maths to look at algorithms. Children are challenged to solve missing number problems in number sequences, using logical reasoning. Additional challenges are then presented, and children are asked to share not just the answer, but the approach they took to solving the problem and...

Beat the Clock - Sorting Networks

Even though computers are fast, there is a limit to how quickly they can solve problems. One way to speed things up is to use several computers to solve different parts of a problem. In this activity sorting networks are used to do several sorting comparisons at the same time. This resource begins with a discussion...

Swap Puzzle

Using a set of simple ‘swap puzzles’, this CS4FN activity helps students to learn, fundamentally, what an algorithm is and how they can be made more efficient. Students are encouraged to create algorithms for solving the puzzles which can be used by future players to win, with no understanding of the game, in as few...

Scratch programming in primary schoolCV001

Scratch is the most popular tool for computer programming in primary schools around the world, and is used independently by millions of children for their own projects. Its block-based, drag-and-drop system supports accessible, creative learning for children of all abilities and levels of experience. Children can...

Divide and conquer

This activity provides a mathematical problem that is solved in a simple way. It relates to the way algorithms are used in search engines and links to problem solving in maths. The context is that of Santa trying to find his socks in one of 1024 boxes, which a clever elf solves for him. Children can then go on to...

Tour Guide (Companion to the Knight’s Tour Activity)

Containing two linked activities, these resources from the CS4FN team introduce graphs to represent inter-related data and algorithms to negotiate them. Suitable for non-programmers being introduced to algorithms, the two challenges – the Knights Tour and the Tour Guide – are similar. Both use graphs as...

Ice Roads - Steiner Trees

Sometimes a small, seemingly insignificant, variation in the specification of a problem makes a huge difference in how difficult it is to solve. This activity, like the The Muddy City problem, is about finding short paths through networks. However, this activity allows for the introduction of new points into...

Invisible Palming

This activity from the Computer Science for Fun (CS4FN) team at QMUL is an introduction to algorithms suitable for those in upper primary school. A ‘self-working’ magic trick is shown – this is a trick that works every time, as long as the process is followed exactly. No understanding of the trick is needed by the ‘...
