Khan Academy
Supporting grades: 34

Description: Learn to use regrouping, or carrying to add 709 + 996, 373 + 88, and 149 + 293. Created by Sal Khan. But as you do them, I want you to really keep in mind and think about what the carrying actually means. Well, we can write the 5 in the ones place, and then we can carry the one. Well, we put it in the tens place, one 10 represents 10.
