Press on the audio buttons to hear each of the slides being read aloud. You need to use the tool to underline the key words and circle the important numbers in each of the word problems. You need to decide if the problem is multiplication or addition. Hint: multiplication problems have equal groups. Write out the number sentence and solve the problem. On the final slide, use the tool to write a multiplication problem for the number sentence provided. Make sure that you have used words such as 'groups of' or 'each'. Reread your problem carefully and edit it using CUPS. Use the number line given to you to solve the problem.
