The most basic math tool that ensures engagement and allows for
practice time after time without any extra time on your part. Once
made a folder will last year after year starting out shortly after the
skill has been introduced and going through review and even home
work practice. This resource includes 10 different folders, all the same skill. I model this job, then give students a partner for the
first time. I tell my students to pick out their favorite the next time
we do them, then later they have to pick a folder they have never
done before. It keeps practice fresh.
