In this activity, students will practice sorting their ADDITION AND SUBTRACTION facts into three categories, odd answers, even answers, and answers they do not know yet. Once students are done sorting all of the answers they know, they will go back to their “I don’t know yet pile” and use any strategy they have learned in order to solve their problem. You can have students check one another’s work, use a calculator, take a picture of it using an i-pad, have students record their answers on the recording sheet, just to name a few!
