Random Chants: Generating a lot from a little using Excel

In this article, I describe some simple ways I use random numbers in Microsoft Excel to help learners develop fluency and flexibility and gain some mathematical awarenesses. Chanting of multiples using random numbers has benefits, but it is possible to broaden learners' conceptual understanding beyond repetition using simple random number generators. [...]shifting attention onto the language might enhance the fluency through the process of subordination (Hewitt, 1996). If you want to interleave in practice of recognising primes and composite numbers, you could do this by generating random numbers from 1-100 (or higher). =randbetween(1,100) Learners could respond with a fact such as, "6 x 8" given 48 or with the word, "Prime", given, say, 47.
