These games will develop familiarity with the number system and "landmarks" such as 10s, 100s, 1,000s, 10,000s and 100,000s.  The games will provide engaging opportunities to practice computation.  At this level, you will find that your child might need to practice some addition or subtraction facts, as well as multiplication or division facts.  Choose to work on only one or two facts at a time.  After those two facts are mastered, move on to one or two more.  Keep the task small to build confidence.
