Word problems and puzzles — 3-digit subtraction (2nd grade math)
A few word problems for 2nd or 3rd grade math. One involves both addition and subtraction (3-digit). Another, once again, lacks the actual question so Mathy and I discuss that for a while. Lastly we will do some missing number puzzles (3-digit subtraction, with regrouping).
The first part of this lesson teaches regrouping one hundred as 10 tens (in subtraction).
