first thing you should do is find some english songs and rhymes for twos and little children. You can search the BBC site CBEEBIES if I remember it corectly, or the BBC site www.learningenglish.org. You will find songs such as 'this is the way' or 'Old Mcdonald had a Farm'. as well as Fairy tales Little Red Riding Hood, etc. First try to show what the song or the story says using pantomima. You can also buy cards with the picture of a dog and explain that it is a dog, there are almost 21 such cards. Or you could buy the cards with Dora the Explorer. But remember you should be the actor showing the pictures and then asking them to repeat. You should introduce yourself and play with them.
