Over the last few weeks I have been using this great site to introduce Kindergarten students to the laptop:

Here students can practice using the track pad to move the arrow and click & drag. I’ve been very impressed by the number of Kindergarten students I have seen practicing using only one hand! Way to go!!

Remember to allow your students time to continue practicing on the computers. Keep up the great work!
