We have seen several variations on the concept of the number of the day everywhere. If you have not, it’s time to implement this powerful way of assuring students are making gains without any comprehension gaps.
With the number of the day, students in the fourth grade are reviewing basic mathematics skills that are supposed to be part of their foundation in order to gain new skills. It can used as a weekly or monthly homework assignment as needed to assure they have those skills down. If it isn’t a challenge for them, even better! It should be a tool on an as needed basis so you could move it to every other month or even apply it individually to targeted students.
In my room, it started as a once a week guided classroom activity which then progressed to a weekly homework to a once every six weeks homework and an eventually to an individual targeted tool. I definitely recommend trying it in almost every grade, with customized parameters.
You can download a PDF here and I will soon be adding some different variations I have created. Comment here to let me know what variations you would like to see so I may make them available to you.
