Math in kindergarten should be hands on - working from concrete experiences, to pictorial, to the abstract as students gain a greater understanding.
Concepts are addressed in a large group setting through calendar activities, direct lessons, everyday routines, graphing, sorting, counting rhymes, etc. in relation to the theme or literature being studied, independent and small group work at centers and tubs, and one on one skills practice.
