Math

Please complete these 8 questions in your notebook. Remember to show your work. Try to use different strategies to solve the questions, particularly those that involve subtraction. For example, use an algorithm to solve one subtraction problem, a number line another and making an easier question for another. 

Extra practice for test. These are not homework questions.
