We have been looking at how to add two, two digit numbers using the hundred square.
Last week we looked at adding multiples of ten (10, 20, 30, 40) and now we have been using this to first add the tens and then add to ones. We noticed that it always makes an ‘L’ shape.
Some of use even created our own word problems today.
The teachers favourite all involved food. I went to the shop and brought a chocolate bar for 43p and then spent 25p on pick and mix. How much money did I spend?
What questions could you create? Try out some more on the hundred square here: http://www.primarygames.co.uk/pg2/splat/splatsq100.html.
