Hey,
I started teaching my daughter by writing it on a rough Diary.... Like capital A is - Up-Down-Cut... Capital L is - Down-Out.... Capital M is - Up-Down-Up-Down.... Then one fine day when we were waiting for someone in front of a building... She tells me "Mamma see up-down-up-down --"M"..... I was so thrilled.....
Colours are a little confusing for kids, so often they mix it up... They mean to say something, but end up saying something else..... So everytime you pick up an apple...say See Red-Apple.... See Yellow-Banana.... See Green-Grapes... See Green-Pears..... It'll be easy to associate the colours to the items....
Happy tutoring!!!
