This is a blog that I especially like: Miss Andrea's blog.
It is full of resources for the teaching of English as a second language to very young learners (kindergarten - "infantil"). Andrea has made a deep research on the net finding materials, worksheets, videos... and stuff for IWB, too!
One of her last posts is all about working Autumn in the ESL class. A PowerPoint made by her is the starting point to develop this memorable season.
It is worth to have a look!
And do not miss the page about Halloween with lots of resources to be used in our classes.
Thanks a lot Andrea!
