These games will develop familiarity with the number system and "landmarks" such as 10s, 100s, 1,000s and 10,000.  The games will provide  engaging opportunities to practice computation. Students need to practice addition and subtraction facts, as they move on to multiplication and division concepts. If you find that your child needs work on some facts, choose one or two facts; work on those facts, then after they are mastered, choose one or two more facts.  Limit the number of facts you are working on.  Success builds confidence.
