I took the idea of race round the clock multiplication sheets from Matt7, wrote a spreadsheet that randomised the multipliers and extended to idea to a few other scenarios. It's fairly easy to adapt, if anyone is unable to do so but wants a particular feature let me know in the comments section and I'll try update. Enjoy.

Battleships has often been used in the classroom but has led to pupils being confused between coordinates and grid references, this leads to problems when numbering axes (boxes rather than lines) Battleshapes seeks to address this by providing ships represented by a variety of 2D shapes. HMS Square, USS Rhombus, HMS Kite etc Pupils sink ships by hitting the corners of each shape. The resource is a Powerpoint file and is fully editable. To add some differentiation I have included sheets where the grid is numbered, partially numbered and not numbered. An additional sheet is included for those who prefer to talk about vertices rather than corners. As with any resource, please make sure your school pays for the resource and not you.

This is an example of the print outs obtained from a spreadsheet I have produced. The spreadsheet uses randomly generating numbers to create a unique set of questions each time you press the F9 button. The main feature of this spreadsheet is that it allows you to modify the numerical range of questions. All questions are set for a maximum sum of 100 but if you need a question sheet for pupils with a maximum sum of 30, simply change the valuesin two cells and print it out. https://www.tes.com/teaching-resource/bar-models-spreadsheet-maths-mastery-practise-11375053
