These aliens will be familiar to any mathematicians who have seen Toy Story! Use an array of them to practice addition and writing number sentences. Because this worksheet includes the explanation to its one problem, project it as an all-class warm up. After examining the array, scholars write the corresponding addition sentence with its answer below. Note that the array doesn't necessarily make the intended number sentence clear, which is another reason you should guide learners through this practice.
