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. What are you waiting for? Grab your copy of these flexible and highly useful Python challenges immediately. Your students will love them.

A top card game to teach the history of computing. This fun, familiar and easy to play card game reinforces the rich history of computing since the early electronic computers to the modern day.

SET-UP INSTRUCTIONS Print out the cards in colour and laminate them before cutting them out. You will need enough copies for one set between 2 people, so for a class of 30 students you will need 15 complete sets of cards. It is a good idea to keep each set of cards in a separate plastic bag so the sets don’t get muddled together. There are 36 ready-to-use cards in each set. PLAY INSTRUCTIONS Split the class into pairs but if there is an odd number, one group can play as a three. Shuffle and deal out all the cards in a set, face down equally between each person in the pair/three. Players look at their top card only. Player 1 chooses and calls out their best category and value (e.g. “Weight – 544 Kilograms”). The other player(s) look at their own top card to check if they can beat the value for the same category (highest value wins). The player with the highest score for that category wins all of the cards that are being played and adds them to the base of their pile. The winner of the round chooses the category for the next round. The first player to collect all of the cards wins! Help your students learn how computing technology has changed over the years. Download this history of computing card game now to add this easy-to-use activity to your teacher’s toolkit and use it for years to come.
