#### Converting Length Lesson - cm and mm

A fully resourced lesson that focuses on being able to convert between cm and mm. The lesson presentation focuses on a range of questions and building understanding as well as guided practise questions for children to practise what they are learning. This is followed by one of two sheets based on confidence (answers included) before a final challenge question on the lesson presentation.

#### Disney's 'Up'-themed Compound Shapes Activity

Attached is a floor plan for both the ground and 1st floor of the Ellie &amp; Carl Fredricksen Residence from Disney's 'Up' (pictures taken from Google). I have added measurements so that pupils can use their knowledge of compound shapes to find the missing sides and ultimately work out the perimeter and area of the rooms in the house (I have also added the publisher version, should measurements like to be altered). From here, they can use the additional activity of determining how much it will cost them to decorate certain rooms. I would recommend using this with high-ability KS3 classes (but you may use it however you like!). I hope this proves to be useful/fun for your classes. Enjoy, and please leave feedback if you can!

#### Pythagosaurus Rex - prehistoric Pythagoras Problem Solving!

Continuing the dinosaur theme I made this for my very bright top set year 8 class, although it has worked very well with higher tier GCSE classes also. Students need to work out the perimeter of the different prehistoric creatures that are made from triangles, rectangles, circles etc. There is a class example Pythagosaurus Rex with a scaffolded printable answer sheet. There is also a spot the mistake task to address any misconceptions with Pythagoras before attempting the main sheet.

#### Treegonometry - problem solving with trigonometry, Pythagoras and trees!

My GCSE higher tier class loved this so it was well worth all the effort put into making it. Really applicable to the new GCSE specification, you need to work out the area of six trees of increasing difficulty, made from triangles, rectangles, parallelograms and trapezia. Included is the worksheet in PDF and also Microsoft Publisher format, and a class example on Microsoft Powerpoint.

#### Area of Parallelogram & Triangles - Year 6, Key stage 2 (US 5th grade)

In this lesson, learners will be able to: calculate the area of parallelograms and triangles relate the area of rectangles to parallelograms and triangles, for example, by dissection, and calculate their areas, understanding and using the formulae to do this. Lesson can be used as whole class teaching by teachers and at home by learners. Lots of drag and drop activity with instant feedback. To access online choose the multiscreen.html file. To access offline choose the swf file. Contains 32 Interactive pages

#### Perimeter and Area Revision Interactive Spreadsheet

An Excel Workbook containing eight spreadsheets to practice the GCSE skills of finding perimeters and areas of rectangles, triangles, a trapezium and circles. All sheets have 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!

#### Maths Word Problems for Year 4-6

This is a collection of word problems aimed at students in Year 4-6. (High ability group for Year 4). There are four quizzes included each with ten questions. All answers are included. The quizzes cover different strands. The topics covered are as follows: Fractions of money Fractions of amounts Time problems Money money problems Perimeter and area Subtraction and addition multiple step problems Ordering fractions and decimals The questions vary in difficult but are sure to keep the class busy. I find these questions especially good as an extension, a pop quiz or to use one or two at the beginning or end of a lesson.

#### Simultaneous equation linked with area of a trapezium.

Ideal for KS3 and 4. Links simultaneous equations with finding the area of a trapezium. The lesson is planned with solutions and diagrams. Powerpoint/pdf filetypes.
