This time my goal was Use a broad range of mental strategies to solve addition and subtraction problems.
The strategies were Equal adjustment, Place Value and Reversibility .
My favourite was probably Place value because it was the easiest for me.
A place value question!
552+231=?
All you need to do is add the hundreds together.
500+200=700
And then add the tens together
50+30=80
And then add the ones together!
2+1=3
So the answer is 783!
Did you learn anything new?
