Workshop 5 - Cooking Bolognese (Critical Path Analysis) Have you got time to cook, wash up and eat before meeting your friends at the cinema? What time do you need to start cooking and how long will each step take? This workshop uses critical path analysis to solve problems. Curriculum areas covered: GCSE: apply the four operations to integers use standard units of time, using decimal quantities where appropriate A Level: Interpret and communicate solutions in the context of the original problem. Understand, interpret and extract information from diagrams and construct mathematical diagrams to solve problems, including in mechanics. A Level: Decision/Discrete maths Completion of the precedence table for a given activity network. Construct, represent and interpret a precedence (activity) network. Use critical path analysis and be able to interpret outcomes, including implications for criticality. Determine earliest and latest start and finish times for an activity network. Identify critical activities, critical paths and the float of non-critical activities. This pack includes:  Cover Sheet  Student Worksheet  Presentation  Teacher Notes  Diagram cards The OR technique featured in this workshop is critical path analysis. Critical path analysis is a popular project management tool, it shows the shortest time needed to complete a project and factors in which tasks are dependent on others.

Game #4 - Making Paper Cups - Paper Cup Challenge (Improving Processes) The aim of this pack is to introduce students to one of the topics of O.R. in a fun and engaging way. Firstly, we get students folding paper up, down and across to make paper cups. Then the challenge gets technical (and competitive!) - teams are timed building paper cups, and must organise the task into sub-tasks - such as folding or designing. This leads onto thinking about efficiency and process improvement. What worked? What didn’t? Lets time it and do it again! The students have a chance to make changes to their process before comparing the means, standard deviations and variances. Aimed at: Secondary school  For Year 7-9 / Low ability groups: Allow 90 - 120 minutes  For Year 10-11 / Average ability groups: Allow 60 - 90 minutes  For Year 12-13 / High ability groups: Allow 45 – 60 minutes The material uses: Mean, Variance, Standard Deviation, addition, subtraction This pack includes:  Student worksheet - short version  Teacher notes  Presentation  Cover Sheet  Case Study  Excel data  Additional Resource (Crown Paints) The O.R. technique behind this is simulation and improving processes (looking at the most efficient way of doing something). This information is also available online to download.

Game #2 - Playing Snakes and Ladders - Climbing the Career Ladder (Algorithms) The aim of this pack is to introduce students to one of the topics of O.R. in a fun and engaging way. It uses a specially designed board game to engage students by moving around the board, and exploring the different careers and opportunities available to maths students. Perhaps you become a mathematical comedian and move forwards 4 spaces, or perhaps you buy the wrong plane for B.A. and move back 2 spaces! This then leads onto how a board game is designed, flow charts and the algorithms behind it. Aimed at: Secondary school  For Year 7-9 / Low ability groups: Allow 90 minutes  For Year 10-11 / Average ability groups: Allow 60 - 90 minutes  For Year 12-13 / High ability groups: Allow 60 minutes The material uses: Counting, Flow charts, Algorithms This pack includes:  Board game  Career profiles  Work experience cards  Cover sheet  Presentation  Video Q&A sheet  Teacher Notes Not included but provided on a school visit:  Counters  Dice The O.R. technique behind this is Algorithms.

Workshop 3 - Theatre Bookings (Bin-Packing) You’re in charge of organising bookings and seating for a theatre company. You have to decide who sits where, if anyone sits by themselves, and what to do with people who book in a group. What’s the most efficient way to seat people? How do you take into account audience preferences? Did you know that there are bin-packing algorithms that can help? Curriculum areas covered: GCSE: whole number theory structure & calculation A-Level; Decision/Discrete maths: definition of an algorithm working with & implementing algorithms awareness of uses and limitations of algorithms bin packing algorithms This pack includes:  Cover Sheet  Theatre Modelling Pack (theatre seating grid and booking groups)  Presentation  Pros and Cons of Algorithms Sheet  Teacher Notes  Student worksheet  Answer Sheet The OR technique behind this is algorithm is more formally known as a bin packing algorithm because one is packing different groups sizes and seeing how many “bins” (i.e. rows, in this case) the group sizes fit in, in order to use up the minimum amount of space possible.
