What does this 2nd grade addition and subtraction unit cover?

In 2nd grade, children learn to add and subtract within 100 fluently and within 1,000 using place value, including regrouping (carrying and borrowing). By the end a child should solve problems like 47 + 38 or 352 − 168 and explain why a ten or hundred is regrouped.

How does RepeatWatch help with regrouping?

Set an A–B loop around one worked example, such as Khan Academy borrowing a ten, so it replays on its own. Drop the speed to 0.75× for a tricky step, save lesson parts on keys 1–9, use Repeat one on a regrouping song, and Stop after N loops to keep sessions short.
