Activity 3

Column subtraction with more than one exchange


Before you answer the questions, watch Part 2 of the video. You might like to watch Part 1 again as well. 


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!
