Before children learn to connect numerals with quantity, they need experience counting. Seeing groups as a whole instead of needing the count each dot one at a time is called subitizing. Subitizing is a great routine to practice with early math learners. I suggest starting with a dice and letting students have experience being able to "see how many" without having to count. Once they are able to see the arrangements 1-6, move on to dot cards. The cards I created are different arrangements of the numbers. Have fun.
