Use the controls to change the behaviours of the counter. Investigate different number patterns and make predictions. Turn on the musical notes for a new numerical experience.


Fast

Slow

Maths teachers will see the potential of this application and be able to dream up activities for using one, two or three counters projected onto the whiteboard for the pupils to watch. There are some ideas below but please add more in the comments:

Chanting

Probably the most basic idea for using this application is getting the class to 'chant' their times tables while watching the counter (set the step to the value of the times table and the start number to zero). Now challenge the pupils to close their eyes as much as possible as they learn more and more of the multiplication facts.

Musical Notes

Set the number of notes to 10 and then set the counter running counting in steps of 1. Now change the step size and listen to the sequence of musical notes. What does the five times table sound like? Now hide the numbers or turn the screen off to see if pupils can work out the number patterns by ear.

Body Language

Introduce rules for the various types of number (but not too many to start with) such as: Stand up if you see a prime number then sit down on the next prime number; Wave your hands each time you see a square number; Nod your head on each multiple of nine. Now start the counter and enjoy the spectacle!
