Next Level Numbers!

 Next Level Numbers! 


Hi! I'm going to show you, in the slide, how to use tidy numbers to solve addition and subtraction problems! Here is an example: 456 + 367. Since this is an addition question you would take away from one number and add to one number. Since 367 is the closest to a tidy number, we would add 3 and it would make 370. That means you would take away 3 from 456, which would make 453! In total, the question is 370 + 453 = 823! Bye, and do you have a maths problem solving way you could share?

    Hi Gus - great to see what you have been doing in Maths. You have written a good explanation of the strategy. I also like the catchy title. I think you could improve your slideshow with a little bit of colour. Have you learned any other new strategies?
