Practice Time Number a sheet of Paper 1-12 SKIP A FEW LINES IN BETWEEN EACH NUMBER—you will need to show your work. Put your name on it. a) You will walk around the room and answer the Questions that are on index cards. b) When you get to a number show the work under the question on your paper  c) Some numbers repeat to make sure that not more than 2 people at time is at a number. If you have already done question 1 and see it again around the room….DO NOT DO IT AGAIN 
