1. A fourth-grader needs help with reading comprehension. What are 3 things you will show him on Learning Express?
First off, I would show the 4th grader the site.  Then click on Elementary School, Reading Skills Improvement.  I guess at this point, there are several options to choose from.  The 4th Grade Reading Practice has a Grade 4 Reading Comprehension Practice 1 and a Grade 4 Reading Comprehension Practice 2
After getting this practice, they can proceed to some of the 4th grade tests.  It looks like they can learn comprehension skills on many of these practice tests.  Great for building confidence.
