These tasks all encourage you to explore and describe number patterns, and in particular to use what you know about factors and multiples. They would be best done in the order below as you will find that the later tasks build on ideas from the earlier ones.

As a set, these activities will give you opportunities to work on all five key ingredients that make a successful mathematician: understanding, skills, problem solving, reasoning and attitude. To find out more about these five ingredients and suggestions about how you can reflect on becoming a better mathematician, take a look at our short article What Makes a Good Mathematician?.
