Before you answer the questions, you may find it helpful to watch the Activity 2 video again, especially the last calculation.
Then use the exchanging skills you honed yesterday to answer the Activity 3 questions.
Remember to record your exchanges very carefully! If you don't have a printed copy of the sheet, you can just record your working and answers in your exercise book, or on a piece of paper.
When you've finished, check your answers with the answer sheet.
Send us a message if you have any questions or need help with any of your answers. We love seeing what you're up to!
