There are a few simple things teachers can do in the classroom to make a dramatic difference to left-handers in their early years at school and avoid problems as they develop through the education system.
These are basic things such as:
Sitting a left-handed child on the left side of writing areas so they do not bump elbows with the child next to them
Demonstrating a correct writing grip and encouraging an effective writing position
Having left-handed scissors available and know how to use them.
Understanding that left-handers will form some letters in a different direction to right-handers.
