   When the colour coded worksheet is completed, it can be compared with the numbered coloured pictures which are provided as answer keys and can be found towards the end of the resource.    This resource is an engaging activity which can be used by the whole class or a purposeful activity for ‘fast finishers’.    

This type of resource is particularly good for students who are new to English. Newly arrived students are often very stressed and tired at first because of the new environment and culture shock. If new arrivals have been educated in their home countries, they are often good at computation. These worksheets provide relaxing purposeful activities for new students who often need time out from the class work. Comprehension of English is not necessary for successful completion of the colour coded worksheets. The results also provide insights into each student’s ability in mathematical calculations. In the early days, providing opportunities for students to experience success is a way of reducing stress and building confidence, both of which are conducive to learning.
