A good teacher should be able to adapt math to his level and espec. a K teacher- since many kiddos in K can not read.

Lots and lots of visuals. If he is doing most of it mentally-- then showing visual steps to his thoughts to build a good foundation. If he is doing mostly digit work then add some visualization.

Good 'math' topics that lend themselves to visual work (and no reading) is fractions (tactile shapes), weight sorting with a balance scale, dominos, using a ruler, patterning (ABCD or AAABBCAAA____- challenging patterns!), simple verbal story problems, teach symbols and signs (_, + ,=, etc), visual math with cubes to show different ways to do something ( 3 ways to show 6 or 2 ways to show 2+5, etc)

I will say that in 1st- our math curriculum had a lot of reading! It also had math machines....prealgebra stuff. _____ + 5 = 10 and so on.
