Notes

This comes after the number rods.
Sandpaper numbers represent essential information for memory, because you can know any number after you know 1 – 9 and 0.
Writing sequence begins with a chalkboard, the child writes then erases and writes again. First we use a blank chalkboard then a lined or grid chalkboard.
Sandpaper numbers can also be used as a remedial device for children who incorrectly write numbers.
