To give you more practice of arithmetic type questions, we will be setting 3 levels of challenge with 3 questions in each challenge level. You need to complete AT LEAST 3 questions. You can choose your challenge level. If you find one challenge level too easy, move on to the next. CHALLENGE: Can you complete all 9 questions? CHILLI 1: Column multiplication - 2 digits x 2 digits CHILLI 2: Column multiplication - 3 digits x 2 digits. CHILLI 3: Column multiplication - 4 digits x 2 digits. There are answers on the final slides. Once you have finished a question, go to the answer slide, move the box covering the working out, then go back to your answer and mark it. If you didn't get it right, you need to look at your working out to find your mistake and edit it in GREEN (change the colour of the pen or text using the colour bar down the right hand side). Once you have finished all the questions and you have marked/edited your work, click to submit your work.
