When I taught Special Education, Maths was a subject that was very hard to teach to my students. Some things worked, but most didn't. Whilst doing a day of casual on Monday, the teacher had a Daily Maths Drill book that she went through with the students, each day. It covered the days of the week, months of the year, counting 0-10, 0-20, 0-100, 2D & 3D shapes, and time.
I loved it!!! Such a simple, yet repetitive activity wouldn't bore these kids, but would mean that eventually they would retain some of the information from the booklet. So... I decided I'd create my own for future use - in my own classroom, or for casual teaching. You can check it out at my stores!!
