First of all, one thing is clear. Homework in Elementary School is ineffective. There are no data at all to support the value of giving homework to students in elementary school. In fact, there isn’t even a positive correlation between homework and achievement. 
- It may make them feel stupid. (Over and over again, they’re reminded of what they can’t do.)
- It may get them accustomed to doing things the wrong way, because what’s really “reinforced” are mistaken assumptions.
- It may teach them to fake it, perhaps by asking someone else for the correct answers, to conceal what they don’t know.
- Finally, the whole exercise subtly teaches that math – or whatever subject they’re doing — is something people aren’t expected to understand. 
So what is a teacher or a parent to do in order to help their child become a better student? One thing is to play tabletop games… really. For younger children games help with the following:
- number and shape recognition, grouping, and counting
- letter recognition and reading
- visual perception and color recognition
- eye-hand coordination and manual dexterity 
Here are some suggestions of games based on age http://www.connectionsacademy.com/blog/posts/2015-04-02/Family-Game-Night-Using-Board-Games-to-Improve-Students-Critical-Thinking-Skills.aspx
Of course, we would like to think that our games fall into this category too!
