Subtraction Story Problems_Separate Result Unknown, Separate Change Unknown
I created this activity because my students needed extra practice with reading story problems and deciding for themselves which numbers to add to their number sentence and in which order. First, they practice fact families, which help with the Change Unknown problems, then they record number sentences for Result Unknown and Change Unknown problems. Students like these story problems because their names are used. This is a PPT download so that you can change the names in the story problems to fit
