Our district just started Expressions this year, and the first grade rooms in our school all started the units this week. We are all a little curious as to how others teach the lessons. We have all tried different grouping strategies, and agree that we don't like the large group-we are loosing the really high and really low kids as they are pretty bored. Our kindergarten is very hands-on, play-based, so sitting and doing worksheets is quite a change for these little guys! We would all like to use Math centers, but see how that could be challenging to try to get in all of the info when we only have an hour. Any ideas?
