Kumon book of addition.

She wrote the numbers 1-20 and did a few simple addition problems.  Pages 10 and the top part of 23. I am going tofeet a number line to help visualize adding/subtracting.  Also I am looking into teaching her mental math as she goes, like 6+5 seems hard, but it is just 5+5+1, and she knows 5+5 is 10.   She did  this and other similiar problems today.
