Geometry Lesson
This PowerPoint covers angle definitions and properties that Year 9, 10 and 11 students need to cover. This includes angles on a straight line, in a triangle, interior and exterior angles of a polygon and parallel lines. The lesson should take approximately an hour from start to finish. All the answers are included in the PowerPoint and there should be time to discuss and explain each concept as you work through the slides. Ideal as a wrap up to an angles or gemetry unit of work.Download Now Year / Level:

Understanding Graphs
This Excel spreadsheet has 16 worksheets and allows teachers to illustrate straight lines, parabolas, cubics, hyperbolas, circles, logarithmic and exponential graphs. Each particular worksheet allows the user to change the different values of equations and then view what happens to the resultant graph. Students can quickly visualise what happens to the graph when you change an equation. The first few worksheets on gradients, linear patterns and equations could be used at year 9 and 10. The majority of the worksheets are best used as an introduction to NCEA Level 1 and Level 2 graphs. Students will quickly get the idea of how to link equations to each particular graph. Note that when you load the worksheet you will be asked whether you want to enable macros and links. Answer YES as this ensures that all the functions and graphs work. -
Drawing Graphs (Excel Spreadsheet)
This early Excel spreadsheet draws straight line graphs either when given 2 points or the values for the gradient (m) and y intercept (c). It also draws a table of values for a given start value and increment. This is a great alternative to a graphics calculator.
We have kept this file on the site but we do recommend the other file "Understanding Graphs" as it covers a lot more types of functions. -
Encrypted Messages
This is a PowerPoint designed for a one-off lesson on encryption. It features 3 encrypted messages. The first is a verse from Lewis Carroll's "The Hunting of the Snark", the second is an encrypted message that has 3 parts - the message itself, a hidden number inside the verse both of which then point to a planet in the solar system. The last is a 3 x 3 (9 letter) square where all the letters stand for a number. In each of the cases clues are given for students to decode the messages. Teachers should read the PowerPoint first as all the answers are contained in subsequent slides. Ideally the class can be divided into groups of 2 - 4. If you are unfamiliar with Lewis Carroll then the first few slides explain about the man and the verse. It is a fun lesson for end of term or Friday afternoon and has been used successfully as a 1 hour lesson activity at both Year 9 and Year 10. -
The Turning Square (Bloxorz Clone)
This is a copy of the popular Bloxorz game but with a number of enhancements. The file is in WinRAR format. You need to download and save the file onto your computer. You then unzip it into a folder. Once unzipped you load the application called "Turning Square" to play. The game is great for spacial awareness as you use the cursor keys to rotate a rectangular block around the maze and place it into the hole to get to the next level. There are a number of enhancements to the original Bloxorz game in that you can skip to different levels, the answer can be demonstrated and there are also different levels of play such as ice mode where the block is likely to slide where you don't want it to go. In all there are 33 levels of play. -
The Number Factory
This resource comes with teacher notes and 3 sets of templates to photocopy for your classes.
"I Know Your Number" is fun activity that students cut out and show to their friends and family. The template can be photocopied onto normal paper or card. Students use these to "guess" their friend's number.
"Five Card Addition" contains level 2 addition and is also a lot of fun. By turning their back and only been given the colour of the cards then a student can correctly guess the total. The exercise is also a good introduction to BEMA (order of operations).
"The Mind Reader" has students performing additions for totals up to 63 as they correctly "guess" a friend's number. Therefore they should be practising some good numeracy strategies in each of the additions such as making 10s and adding in parts. -
The Pasta Factory
In this exercise students get to learn about prime numbers and why they are necessary. The lesson revolves around a Pasta Company that relies on machines to stretch the pasta to different lengths between 1 and 100 for its customers. Some of the machines break down and the staff at the Pasta Company have to come up with a solution of providing different pasta lengths even if a particular machine is not working. The lesson contains teacher notes and a student hand out. -
1000 People Silhouette
What will be the odds? What does it mean when you read that heart attacks kill 1 in 5 people or that 1 in 8 women will get breast cancer? What does it look like when taken in context to a population? If taking a particular medicine improves the odds by 20%, how many will now survive? There are 4 pages in this document which give 1000, 200, 500 and 10,000 people silhouettes. They can be used in statistics exercises or by consultants to help illustrate what it actually looks like when given the odds. -
Area of Triangles (Power Point Presentation)
This is another PowerPoint presentation sent to us by a keen teacher. Rather than spend time designing your own PowerPoint you can use this or use it as a starter to your own. Don't forget that there are also area exercises in the "Booklet" section. -
Area of Rectangles (Power Point Presentation)
A keen teacher has sent us this PowerPoint presentation. It is a great to use to help introduce the topic of area of rectangles. Don't forget that there are also area exercises in the "Booklet" section.
