I have listed some of my favourite sites for using the 100 square in your teaching. I have used these as warm up activities for maths on the IWB or have used them on individual computers during maths rotations. They are great for introducing and reinforcing number sense. The 100 chart is so versatile you can use it to teach and reinforce, odd and even numbers, place value, addition, subtraction, division and multiplication, the list goes on. The 100 chart also allows you to see what strategies the children are utlising.

http://www.ictgames.com/100huntadd11.html – a number is identitifed on the 100 square and the children have to add eleven and then click on the number
http://resources.oswego.org/games/SplatSquares/splatsq100.html – I love this game it has a really good splat noise and the children can change the colour of the splat. It allows for a multitude of uses depending on the teaching focus ( You can call a number and then children find it, you can call a number and then say add 5 and the children find it, you can use it for counting and the chn splat on the counting sequence, find odd and even numbers etc).
