Here are the Active Algebra sequences and functions
These activities can be used with pupils aged 10 to 16. The activities can be used either by individual pupils, small groups or with the whole class using a projector or an interactive whiteboard. Select the pattern then use the slider to change the variables and record your results in a table.
Linear functions

Link to the Tables

link to Tables and Chairs
Four repeating shape patterns made from tables and chairs. Work out the rule that connects the number of chairs with the number of tables.
Follow the number patterns and predict the next number.
Work out a rules and explain why they work. Write the rules as a formulas.

Repeating shape patterns made from matchsticks. Follow the number patterns and predict the next number in the sequence.

Matchstick Polygons
How many matchsticks are needed to make 100 polygons? Work out a rule. Explain why your rule works and write it as a formula. Can you work out an overall rule that works for any repeating matchstick polygon pattern?
Matchstick Squares
Three different square matchstick patterns.

Repeating shape patterns made from pink and yellow flowers. Work out the rule that connects the number of pink flowers with the number of yellow flowers. Follow the number patterns and predict the next number.
Work out a rule and explain why it works. Write the rule as a formula.

The flower patterns come in three levels of difficulty:

First-time gardeners
Regular gardeners

link to Elephant Wallpaper

ink to Elephant Wallpaper
Use Elephant Wallpaper to investigate number sequences and nth terms.
A small piece of 'wallpaper' is shown, the aim is to decide what colour the elephant is at selected coordinates. Use the sliders to determine the coordinates.
Click on the elephant of your choice then the 'final answer' button. A much larger piece of wallpaper is revealed showing the elephant in question.

The levels become progressively more difficult. Experts can start at a higher level. The levels relate to those on the Elephant Wallpaper game and so can be used to practise for the game.
