Here are a couple great worksheets for teaching kindergarten math.
Which Number is Bigger?
Here is a simple worksheet to practice deciding which is bigger up to the number nine. Three to four numbers are shown in a box. The student writes the biggest number in the space provided.
Ducks in the Pond worksheet 2
This is such a cute worksheet. Students complete the number story and practice beginning to add and subtract. At the end they get to cut up 4 ducks and paste them in the pond. My daughter loves it any time there is cutting and pasting involved. : ) Learning math should be focused on fun at this age!
