Pre-order Items

Pre-order resources will either have a single dispatch date or a date range. Where there is a date range:
  • The earlier date is the best-case scenario – the date by which we aim to dispatch the resource to you, if the resource sails through quality and similar checks.
  • The later date is given to indicate the latest date by which you should expect the resource to be dispatched.

These dispatch dates may occasionally be moved back, in which case we will notify you. Conversely, publications are often delivered earlier than the dates shown.

Python Challenges for KS3/4

30 programming challenges test students’ application of key programming constructs, including: sequence, selection and repetition; variables, arrays and functions. The increasing complexity aids progression from KS3 to KS4.

Very useful for absolute beginners through to more experienced users... The first tasks are suitable for KS3, but the latter ones are firmly aimed at KS4. M Fairbank, Computing Teacher & Independent Reviewer

Provided in a range of formats, these challenges are equally valuable for teacher-led lessons or independent learning – including homework.

Everything comes in photocopiable and electronic formats:

  • Challenges – provided as presentations, ‘challenge cards’ and a handy A5 booklet
  • Exemplar solutions with comments (Python v3) – including Python scripts; perfect for demonstration before students attempt each challenge, and for comparison afterwards
  • Simple mark scheme – accessible for both teachers and students


  • Teacher presentation – for delivery during lessons; the challenge, solution and mark scheme all in a single PowerPoint
  • Marking grid for teachers (and students) to monitor progress

What do teachers have to say about this resource? (5688)
"An excellent resource that covers learning to program in Python well and in sufficient depth to meet the National Curriculum standards at KS3/4... The problems are clearly outlined and an associated model solution is useful as a learning resource or even the basis for a set of student notes; the difficulty level is about right and even complex tasks like file handling and arrays are covered in a straightforward way." - P Chapman, former HoD, independent reviewer
"A good resource - impressed with how logical it makes it and the exemplars would certainly help teachers that are new to programming... Offers differentiation through independent learning and support that could be teacher led... I liked the use of stars on the challenges, the simple effective mark scheme and use of programs. Exemplars are very good too." - L Price, Head of Computing, independent reviewer
"This resource is very useful for absolute beginners through to more experienced users. The tasks start very easy, but get very difficult by the end. The first few tasks would be suitable for KS3, but the latter ones are firmly aimed at KS4... The inclusion of the answers [in .py format] will be very useful to inexperienced teachers The PowerPoint version will be useful to display on IWBs... Layout is good and consistent. I like the 'skills' required column, which gives the students a pointer as well as reminding them of some of the key concepts in programming." - M Fairbank, Computing teacher, independent reviewer
"Very useful for teachers looking at starting to teach python to students in both ks3 and ks4 and gave scope for the different ability bands... Well-suited for a review or recap session in a lesson to check that the students can manipulate the different syntax and skills learnt in python to start to create their own programs... It could also be used as plenaries after teaching a topic or as a starter to review previous knowledge." - K Sprolston, Head of Department, independent reviewer
"A well-designed resource that will save a lot of time for teachers... I particular like the consistency and the simple division of the slides in three different parts: the challenge, the key elements they need to use and the level of difficulty... This resource can be used as a tool to enhance the learning of the programming theory within lessons or can also be used as a homework tool for the students to deepen their knowledge of programming. In any case, it is a very good tool for independent learning... Provides a challenge to students when revising or tackling for the first time a programming task in Python." - H Gonzalez, HoD, independent reviewer
