At the beginning of each month we do our monthly calendar activity. We did this one yesterday! Many of my students (especially those with autism) love this calendar lesson so much that they actually remind me that we need to do it when we are getting close to the end of a month. And get upset when something interferes with us doing it on the first school day of each month...
Not only is it educational but also gives students a visual for that month so they know exactly what to expect.
Once we are finished with that as a class, I give students a worksheet based on the calendar. I use the basic one each month and just adjust it to fit into that month- super easy, takes me like 2 minutes if even that long.
UPDATE: I have created a monthly calendar TpT product that you might be interested in if you like this product! I have since been moved to a lower level class, so the product includes activities for lower ability students, and I also included higher level skills as well, so hopefully it will be a good mix for most classes!
