Skip Counting to Read Arrays

This lesson teaches how to read arrays using skip counting. It begins with an introduction to arrays and their limitations, using the number 7 as an example. The lesson then provides two examples: an array of cats and an array of Xs, demonstrating how to write equations and use skip counting to determine the total number of items in each array. The lesson concludes by summarizing the key points covered.

What is a common mistake when trying to create arrays with certain numbers?
