Any experiences with Math Expressions? My district just started using it K-5. The length of each lesson seems quite long. I only have 40-50 minutes a day for math which is ALSO unrealistic but the lessons seem to always take at least 90 min. The pacing also seems rather rigorous, especially since the content is CCSS and is pretty challenging. I teach 2nd grade and my class finds a lot of the lesson content difficult. I am finding I need to break up a lot of the lessons over 2 days, as I am finding it's so much whole-class (which doesn't exactly meet the needs of my students.) I don't like how there is a lack of manipulatives and the ones that come in the math kits are flimsy. I think the program will be better in a few years (I hope) when the kids have been using it starting in K.
