The following links are ones that teachers in our school have found to be helpful in reinforcing the skills necessary for second grade.  These games are most helpful when an adult supervises to make sure the child is reading the words or thinking about the problem at hand, not just guessing.  Children should always be monitored closely when using the internet, and all screen time (computer, tv, and video games combined) should be limited.  For information on limiting screen time click Limiting Screen Time.
