In class, we spent time really working on conceptualizing rounding (building number line mountains). Tonight's homework may have taken a while if you did that for every problem. Tomorrow in class we'll talk about a faster strategy for rounding (mentioned in the "brain box").
It's always interesting to see which 3rd graders take the time to read the directions fully. This particular worksheet asks students to circle/box their answers depending on whether they rounded up/down.
