This is a SmartBoard file that teaches how to add double digit numbers without regrouping. It can easily be paired with student manipulatives as you work through the process of addition double digit problems.
Each slide contains a double digit problem laid out on a tens and ones frame. Tens and ones can be dragged beside the numbers to illustrate their meaning and then counted to find the answer. Finally, the answer is revealed by dragging a clip art picture.
As students learn the strategy of simply doing 2 addition problems, the base ten blocks do not need to be used anymore.
