The Learning Station. http://www.learningstationmusic.com
I teach English in grade 2 and 3. Children at that age are very motivated to learn English and need a lot of different challanges to come along.
My experience is that songs are very good tools to engage all the children in the classroom. The level of knowledge in English is very varying in a group. There are pupils with just a little experience of English and they therefore might be shy and do not want to speak English. There are also pupils with a decent vocabulary and they need opportunities to progress. Songs are for everyone.
The Learning Station is a fantastic gold mine where you can find material for almost any lesson in English. They have published over 250 children's songs that are part of educational curriculums world-wide. The Swedish curriculm emphasizing the importans of songs and ryhms in the syllabus in English.
If you have access to a Smartboard you can choose from hundreds of different films and songs, all about things you work with in the lower level of compulsory school. There are songs about the alphabet, clothes, colours, food, figures, animals, months and days among many other subjects. If you do not have access to a Smartboard you can download the music.
The Learning Station has also created a series of free, printable activity handouts. You can find many educational lesson plans and lots of other fun things. The only problem is that there are so much material and you need time to go through it, time that you mostly do not have as a teacher.
One of my and my pupils favourite songs is “Boom Chicka Boom”. You imitate the moves and the song, bit by bit. The pupils love it and they want to do it every lesson. Usually we end the lesson by this song and after 4-5 times they are so good at it. Try it and enjoy!
