The PACT team are at the 2024 annual conference of the Computers in Education Society of Ireland on 2nd March 2024 with a presentation entitled "CT Obstacle Course – How to run a collaborative computational thinking activity in your school". The printable materials associated with this presentation can be downloaded from here:

Associated resources:
CT Obstacle Course Teacher Pack (includes instructions, team answer sheets, class answer sheet, actions sheet, final challenge sheet "Crack the lock code", and solutions)
• If you run the CT Obstacle Course with your students we'd love to hear about it and get your feedback

The Bebras Challenge is the inspiration and basis for many of the resources created by the PACT team (the Bebras initiative is explained at the bottom of the page). Our computational thinking workbooks are available on the Workbooks page. Scroll down this webpage for all of the other PACT resources currently available for download.

Tascanna Smaointeoireachta Ríomhaireachtúla do Sheachtain na Gaeilge
Nua don 8 Márta 2022: Tascanna Smaointeoireachta Ríomhaireachtúla do Sheachtain na Gaeilge (seachtain 2)

Mar chuid de Sheachtain na Gaeilge, tá tascanna Bebras á gcur ar fáil as Gaeilge ag foireann PACT, i gcomhar le Roinn na Nua-Ghaeilge, Ollscoil Mhá Nuad. Scaoilfear naoi thasc in aghaidh na seachtaine, do choicís na féile. Tá súil againn go mbainfidh sibh idir thaitneamh agus tairbhe astu. Táimid ag obair linn i gcónaí ar thascanna Gaeilge a chur ar fáil. Coinnígí súil ar an suíomh gréasáin le haghaidh tuilleadh acu.

Notes on difficulty:
  • The tasks are in increasing order of mathematical difficulty.
  • For native Irish language readers, the mathematical ability needed to solve the tasks is equivalent to that of 8+ year olds for the first 3 tasks, and 12+ for the full set of tasks.
  • For most pupils, however, their Irish language reading ability will determine which tasks are suitable, and teachers should decide for their own classes how much assistance is required.
  • There is no upper age limit, so second-level students will still find some tasks challenging.
  • Please feel free to give us feedback at pact@mu.ie!

  • Where: Online (Zoom)
  • Audience: All secondary years, suitable for CS, maths, and science
This Computational Thinking Science Week event is intended for secondary school students. Together, we will solve six secondary school-level Bebras computational thinking tasks via Zoom. The event will start at 9:45 and last for 90 minutes. During each 15 minute interval we will solve a new task, giving time for discussion and feedback from participants. Teachers/classes can join for any part, or all, of the 90 minutes. Teachers/classes can participate using the text chat function in Zoom.

The Bebras tasks for the event are now available for download. They can be printed and handed out to the class or shared as PDFs electronically with the class.

Click here to book. (Booking closed.)
We will use Zoom for the event. The Zoom Meeting ID and Passcode will be emailed to you on the day before the workshop.

The tasks are from previous years of the International Bebras Challenge, so any classes that intend to take part in this year's Irish Bebras Challenge can use this as an opportunity to practice for the Challenge (https://bebras.techweek.ie/)!

International Bebras Bebras ® (www.bebras.org), founded by Prof. Valentina Dagienė, Vilnius University, Lithuania, is an international initiative to promote computational thinking among primary and secondary school students. It designs one of the most popular gender-balanced computer science-related activities for primary and secondary school students worldwide: the annual Bebras Computational Thinking Challenge (2.5 million participants from 56 countries last year alone, see Bebras statistics).

Bebras Ireland Tech Week Irish Computer Society The Irish Computer Society (ICS) is the National Bebras Organiser for Ireland. The ICS organises the Bebras Ireland challenge as part of its Tech Week activities. Since 2016, PACT members have been the Ireland representatives to the annual International Bebras Task Workshop where tasks for the subsequent international Bebras Challenges are developed. Bebras Ireland tasks created by the PACT team have been translated into tens of different languages by overseas national Bebras organisations and tackled by hundreds of thousands of primary and secondary students worldwide.
