Smartboard Resources by Mrs. Sears. This site is so good! I use it all of the time and always find great activities that match what I am doing in my class. Mrs. Sears has separated the activities by month so just scroll down to January and you will find the snowman/winter related activities. There are so many great things that if you are like me you will be on this site for a long time!!
My students love this song that I found on youtube, called Build a Snowman. It is from HarryKindergarten and they have many other cute songs (and educational songs)!
I know that some people have said that they cannot go to youtube on their school computers but if you have a school laptop that you can take home you can download the youtube videos straight to your computer by using a program like KeepVid or by adding the word "save" in front of "youtube" in the video's url. Then you can play the videos from your computer and not have to even go to youtube.
For example: when you go to youtube to play the video look at the url in the web address bar at the top of the screen it might look like this; www.youtube.com/watch?v=mx8yp - you would insert your cursor before the word youtube and type the word save so that it says www.saveyoutube.com... and hit enter it will take you to another screen and walk you through downloading the video. Hope this isn't too confusing, it really is pretty easy:)
