Adding Double Digit Numbers

Over the past few weeks, our mathematicians have been learning efficient strategies to add double-digit numbers. First, we learned how to add using the hundreds chart. Next, we learned how to add using an open number line. Then, we learned how to add by breaking a number up into tens and ones. Finally, we learned how to add numbers using compensation. Our mathematicians each have expressed a strategy they feel helps them be the most efficient and accurate when solving math problems. Our next step is to learn how to solve one-step and two-step story problems.
