Our Addition with Arrays lesson plan uses the concept of arrays to show repeated addition. At the beginning of the lesson, an array is defined, as well as horizontal and vertical. Illustrations are also presented which show both how a correct array appears and groups that are not arrays. During this lesson, students are asked to write addition sentences for provided arrays in order to demonstrate their understanding. Students are also asked to answer questions about given arrays and complete practice problems involving them.
At the end of the lesson, students will be able to find the total number of objects in an array using repeated addition.
