#### Decisions, Decisions - A Maths Investigation or Discussion Framework: Year 6+

This mathematics investigation was designed for use by children of Year 6 - under the guidance and encouragement of a suitable mentor. It was not intended to be a 'fire and forget' worksheet, but rather a framework for discussion and exploration. The theme is using mathematics to guide (almost) real life decision-making. The focus is on using ratio and fractions to establish probability. Although the material is designed to be challenging but accessible to children working within the government's expectation for children at the end of Key Stage 2, it is possible that teachers of children in KS3 may find the resources useful.

#### Great Graphs - or What do I do with all this information?

#### Data Handling Black Cab Traffic Light Waiting Time

Microsoft Excel required A new set of numbers every time the file is opened 10 different London cabs use the same route during the day and go through 6 sets of traffic lights. An even number means the light is green and the cab does not have to stop and wait. An odd number, however, means the light is red and the cab has to wait at the traffic light. The time that the cab has to wait is in the Waiting Time in seconds column. Use the data to work out the total waiting time in minutes and seconds that each cab had on the journey. Use the data to work out the total amount of waiting time in minutes and seconds, each Traffic Light had. A purposeful resource that works really well as an extension or homework activity.

#### Estimating Mean from Grouped Distribution Interactive Spreadsheet

An Excel Workbook containing a spreadsheet to practice the GCSE skill of estimating a mean average from a grouped distribution using midpoints where appropriate. The sheet has an associated answer sheet going through each question. The questions have multiple choice answers, generated using the answer and potential misconceptions. If the correct letter is given it turns the answer box green, or red if incorrect. Note that your computer will need Microsoft Excel with Calculation Options set to 'Manual' and Macros enabled. There is a set up sheet which gives some advice on how to do this. Clicking the 'More Questions' black square will clear the sheet and recalculate questions and answers. Excel's Zoom Bar can be used to scale the sheet up and down to fit on your monitor. Note that as the questions are randomised, some questions could be repeated. With a constant number of re-generated questions (and answers), students can practice this to their heart's content. After all, practice makes perfect!

#### Averages revision lesson

Made initially for Year 5 at the end of lessons on averages to revise and practise. I used different level worksheets alongside this as main lesson activity.

#### Airline Data Handling

Microsoft Excel required New set of numbers every time the file is opened Data on 10 International Airline companies showing Estimated and Actual Departure times and Estimated and Actual Arrival times - see cover image. 6 starter questions Great, lively resource for the calculation of 24 hour clock time

#### Simple and Back to Back Stem and Leaf Diagrams

A complete lesson for teaching the topic of Stem and Leaf Diagrams. Differentiated starter to check students prerequisite knowledge of ordering numbers and decimals. Examples for both standard and back to back stem and leaf diagrams included, to introduce each to students. Worksheets included with answers on the PowerPoint, for students to self/peer mark all tasks. Exit ticket plenary (these can be printed or displayed on the screen) as a final progress check.

#### Averages and range presentations and differentiated worksheets

I spent an enormous amount of time preparing these for some observed lessons and they are suitable for two to four lessons depending on the ability of the class. They are really well differentiated and really help the students develop a solid understanding of not only the averages and range, but what they mean and all the different ways you could be asked to find them. There are three powerpoints: The mode &amp; median, the mean, the range &amp; making comparisons. There is a corresponding fully differentiated worksheet that goes with each powerpoint, with the level of difficulty increasing as the columns move across the page.
