Initially we developed Excel workbooks, one to practise Addition Facts and one to practise Multiplication facts. Each workbook has several worksheets, each concentrating on one particular strategy. The worksheets are self-correcting and the practice is timed.
These workbooks were the precursor to developing the Times Tables Strategies App and essentially work the same way the App does.
The Excel spreadsheets could be put on the school network for students to access and could also be given to students to take home to practise. However, relying on macros can be fraught with so many individual users and many students did not have PCs.
