Some resources for standard form:

I have been interested in Astronomy since discovering Patrick Moore’s books in the library as a child so enjoyed Richard Byrne’s post on **resources to help students understand the size of the universe, **I particularly like **100,000 Stars**, a visualization of the 100,000 stars closest to Earth. All those lovely big numbers in Astronomy are excellent for teaching Standard Form; I wrote some time ago on the excellent **mathematics resources available from NASA**, see **this on Scientific notation **for example.

Staying with Astronomy, the Royal Observatory, Greenwich has some **outstanding resources on TES**, including **Scales of the Universe** (KS4 – age 14-16)

From the excellent Standards Unit, **N4 on Estimating Length Using Standard Form **works very well as a class activity. (**You can find all the Standards Unit Resources here**).

From Nrich, **two activities on Standard Form**.

**Teachit Maths** though a subscription site offers its **entire collection of activities** as pdfs for free. I have found many high quality resources here for all ages. – try these on **Standard Form.**

From TES Resources – an extensive collection of (free) **Standard Form Resources**, note the 5 star reviews for many resources.

For the start or end of a lesson (or any time!), you could try some **Diagnostic questions on Standard Form. **I created a **Standard Form Quiz** from these questions.

(See **these posts** for more information on the excellent Diagnostic Questions site).

A site with plenty of big numbers is **Is That A BIG NUMBER?**

**(**Post on** Is That A BIG NUMBER)
**

Students could be shown how to check their work on WolframAlpha

and finally some more great links including some rather good animations:

**Secret Worlds: The Universe Within**

You can find lots of data with very large numbers using **Gapminder**

Staying with world statistics, you could try Jonny Griffiths’ **World-wide Statistics task **from his **Making Statistics Vital. **You could use the figures from his spreadsheet – write the numbers in Standard Form and explore some real world Statistics at the same time.
