So writing on a blackboard is fun, yeah? And it allows creativity in a different, freer way 'cause we can just wipe it off when we are finished or if we don't like it or want to try again. But as far as development is concerned there is so much happening:
- fine motor skills
- learning correct finger grip
- getting ready for writing
- handedness - or learning which will be my preferred hand
- control of back and arm muscles develops in an upright, standing position
- colour recognition - that each chalk is different is the beginning of this discrimination
- visual memory and imagination
Scribbling develops the mind so don't rush ahead and show them 'how' to draw.
They may not look like things to you but from about 2 years of age they are to the child.
- Of course the bigger the blackboard the better but if you only have space for a free standing one make sure it is sturdy and won't wobble or tip over. If you have space consider painting a wall with blackboard paint.
