Please be mindful of your child’s handwriting – it is far easier to teach something correctly from the beginning rather than trying to rectify bad habits once they are established.
If you teach in capital letters, your child will copy. This is often demonstrated by your child littering their writing with inappropriate use of capital letters. (Letters from family names are a classic giveaway that this has happened!)
For example; I would naturally write any M, H, E etc as a capital letter in all my writing if I have learnt to write my name in capitals.
Letters (and numbers) should be the correct size (an a should not be the same size as a t ) and they should be ‘sitting’ on the line. Please do not teach your child to only write on alternate lines. It is better to teach them to write smaller, in a more controlled manner using every line.
