Hello!
Where can I start? You need to have some categories in mind, i.e., colours, numbers (up to 10), farm animals, fruit, school objects, sports and seasons. You can find plenty of free downloadable colouring pages when you google them but also easy activities for preschoolers. A good site is dltk, but many more, just Google for the things you wish to teach. Use easy songs from youtube for each category and always repeat vocabulary you have covered by combing categories, e.g. when you cover colours and you teach them animals, you can ask them to colour, for example: 2 blue horses (or 2 yellow apples) depending on the vocabulary you covered. A useful book is Brown bear, brown bear what do you see? which you may also find as a song on youtube. Another one is the very hungry caterpillar and the Spot series.
What you need to do is to have a slow pace which many different and varied activities per lesson. You need to include in each lesson, identification, drawing and colouring, arts and crafts (easy ones because they have difficulties with scissors), singing and especially action songs and dancing.
It �s exhausting but rewarding!
If I think of anything else I �ll send you a message. I hope that helps you for now!
Cheers!
