This free activity provides a hands-on, practical activity to help your pupils learn about binary to hexadecimal conversion and binary, denary, hex conversions. 2 different puzzles are provided in this resource which are simple to prepare and easy to include in your lessons.
SIMPLE HEX PUZZLE
In this puzzle pupils need to fit the triangles together so the matching edges are of equal value. One edge will contain a binary number and the other edge will have the corresponding hexadecimal value. Works well as an individual or paired activity. Includes the values from 1 to 15 (1 – F).
NUMBER BASES PUZZLE
In this puzzle pupils need to fit together squares so the edges match in value. Some are binary values, some are hexadecimal values and some are denary values. This is much harder than the simple hex puzzle and works well as a paired or group activity. Includes the values 0 to 255 (in denary).
HOW TO PREPARE THE PUZZLES
These are very easy to prepare and can be re-used with multiple classes.
You need one printed page for each puzzle you want to use, for instance if you have 30 pupils and want them to work in pairs you will need 15 copies of the puzzle.
Print on card or print on paper and laminate for longer durability.
Cut into separate shapes along the straight edges and put each set in a separate envelope.
Give one envelope to each pair of students and ask them to solve the puzzle.
You may want to provide some scrap paper for your students to use to work out the answers, especially for the number bases puzzle.
Please note this is a PDF file which cannot be edited.
Download this FREE hexadecimal puzzle set today and add it to your teacher toolkit.
You’ll be amazed at how effective this activity is at helping your pupils become more confident with converting between different number bases.
You may also be interested in these wonderful hexadecimal lessons which include an editable copy of these same puzzles.
Are you looking to expand your student’s knowledge of Python programming? These Python challenges give students 7 coding activities all focused on extending their knowledge of Python by using map and filter functions and the lambda expression to simplify their code.
If you are familiar with my best-selling Python book “Python by Example: Learning to Program in 150 Challenges” by Nichola Lacey, these new challenges will expand on the skills taught and give your student’s more coding practice.
Download this wonderful set of Python challenges today to see just how useful they are.
WHO ARE THESE PYTHON CHALLENGES FOR?
These challenges assume students have some knowledge of programming with Python and know how to use input and print statements, mathematical operators and string manipulation. As well as being familiar with using if statements, for loops, while loops and functions in Python.
WHAT IS INCLUDED?
This pack includes a single 5 page PDF which gives your students an explanation of using the map and filter functions and the lambda expression, example code and 7 programming challenges for them to work through.
You also get another PDF which contains printed versions of the suggested solutions AND you get the Python solutions in Python programs so you can open them and look at the code using an IDLE.
HOW CAN YOU USE THESE PYTHON CHALLENGES?
These challenges are very flexible and can be used in a variety of ways. The main PDF includes an explanation, example code and a page of Python coding challenges. Students can work through them individually and the attractive PDF handout makes a perfect homework task.
Alternatively, you can print out the example code and page of Python challenges to give to your class as a starter, plenary or other in-class activity to enable your students to practise using their new skills.
You may even want to isolate the programming challenges into individual tasks, rather than use them as a printed activity to use them in your lesson as small individual coding challenges.
They are also ideal for quick finishers or to motivate higher ability students to keep them interested and learning a new skill whilst you help other students who need a little more reassurance of the basics.
As you have a separate PDF of the answers you can give them to your class at a later date for them to mark themselves, although most students do not require this as they will discover if their code works when they run it and will debug if they find an error. You could also have the answer sheet ready as a help sheet for those who are stuck and need help.
