Use this activity for parent open house or as a class project in Math. Have students answer the questions. Cover each answer with a post-it note that has a math problem on it. Have parent or partner figure out the answers and check under the post-it note to see if they are correct. A great way to get to know each other using math skills. You can set the directions for the class level math skills (addition/subtraction only, addition/subtraction/multiplication of single digits, etc.)
