A reminder of all the great resources on Jonathan Hall’s **Mathsbot** – there are so many activities which students can use whilst working at home; with answers provided for students to check, they are getting feedback as they work. A recent edition is the student version of **Do Now**. Students could try for example Differentiated Questions or a **topic ladder** of their choice.

Nrich is of course an outstanding source of resources. Yesterday morning I thoroughly enjoyed the web version of London Maths – thank you to Charlie Gilderdale for a great session. One of the resources we looked at was Cryptarithms, mathematical puzzles where the digits in a sum have been replaced by letters. This task has a carefully chosen collection of problems of increasing difficulty and it struck me as a good resource that students could work on from home – the problems could be printed off and then students can get away from the screen and work on paper.

For more on working at home, see **Bring on the Maths** and **A Level Mathematics – Have you seen…? **

For World Book Day, I mentioned the various **free books** available; a good time to look at these perhaps. On the subject of free books, Amazon have a generous collection currently of **free Kindle books** (see all the results by scrolling down the page). Education books are included in this collection, for Maths we have CGP’s Key Stage 3 Maths, Book 1, we also have a very useful copy of **Head Start to A Level Maths**. (**Biology**, **Chemistry** and **Physics** are also available.

Visit the museums from home!

From the Science Museum, **Mathematics in our World** which looks at how mathematics connects to so many aspects of our lives and see also this **collection of mathematical objects**. Seeing the Spirograph, a favourite childhood toy reminds me of the brilliant **digital version, Inspirograph by Nathan Friend. **Try altering the gears so that the fixed and rotating gear are the same size, or make one size a factor of the other, make the two sizes have a common factor, or not! Investigate. You can change the colours too and create a work of Art!

For some beautiful images try the **3DXM Virtual Math Museum**. Have a look at all those **plane curves** for example and note that you can select individual curves and change parameters…see **this pdf** for further details.

Have a look at the **Google Art Project **which features Art museums from around the world. The project also has user-created galleries, which teachers can use to create themed presentations of artwork from different collections. Try a search on **mathematics**.
