1. Transum (Starter of the Day)
Using the randomly generated starter as intended can be a little unpredictable, as some are just too easy or difficult, and some are designed to work best if pupils can access computers. Instead, I tend to use the Topics page to search for activities related to that lesson's work.
That said, it's worth looking at the random starter every so often - I discovered the Ice Cream Combinations activity this way, which developed into a whole lesson about listing combinations with Year 8 a couple of years ago.
There's also a load of other useful stuff on there, which is also easy to overlook, but I'm saving those features for a later post.
2. Flash Maths
3. Form Time Ideas
There's plenty of coverage of basic algebra, percentages (including change), fractions, ratio and negative numbers, with an option to print a blank template for pupils to work on. We're using this with Year 11 during form time next year, but I may also incorporate it into standard maths lessons in the run-up to exams.
4. Teachit Maths
Some are worksheet-based, but there are plenty that could be displayed straight away on an interactive board for pupils to attempt in books or on mini-whiteboards. I'll be adding some of these great activities to my Resources section over the next few months!
I particularly like the feature which allows you to enter your choice of numbers into the activity - so, for example, you could create a substitution activity using only negative numbers. The app also works out the answers for you, which is incredibly convenient!
