Subtraction strategies

Today for maths we did subtraction strategies.We had to solve the following word promblems using three different strategies each.The three promblem words was fingers, number line and change to addition.We had to duplicate the slide over again so there can be 19 slides.For fingers you have to make a video, for number line you need a white board maker and a white board.You have to write number line of the question that is on the side.For change to addition is when you write this 14-1=13 and then you have to write it into addition like this 8+5=13.When we record we have tobe somewhere quiet.We  had to work by ourselves when we did subtraction strategies.
