This powerpoint is interactive and color coded. It helps teach the standard algorithm, with not just digits but an understanding that that digit in a specific place value has a worth/value. Example: the digit 7 in the tens place is worth 70. I want the students to have an understanding when they add and a true number sense, and not just go through the motions. There are place value charts, pictures, place value discs, and color coding to help the students understand how to add two and three digit numbers.
I first have the students work through and understand the problems. In my class, I let them work in groups on white board for some example problems in my powerpoint to check for understanding as part of a gradual release of responsibility.
There is no regrouping or renaming in this powerpoint, none of the numbers in a place value add up to more then 9, so they will not have to regroup.
