Terrific Tuesday folks!
So today we are going to recap the INVERSE operation. Remember INVERSE means the opposite action. So if you have subtracted you will add to check your answer.
e.g. 45 - 25 = (if you need to draw out your problem, see pictures below)
Once you have your answer you will do the inverse which in this case is to add. So you will add your answer to the last number in the number sentence. See pictures below.
Write a word problem for one of the problems above. Can you now write an inverse word problem?
e.g. Mrs R-J had 13 bananas. Mrs Edwards ate 6 of them! How many bananas has Mrs R-J got left?
13 - 6 = ?
The inverse word problem would be .....
Mrs R-J had seven bananas. Mrs Edwards gave her six more bananas. How many bananas does Mrs R-J have now?
7 + 6 = 13
