This is small number 1-20 for lanyard use. Inch and half to two inches in size.
During the school year I teach pre-k students the numbers slowly and only put 2 or 3 on my lanyard at a time. While they are lining up I am asking them questions about the numbers. What is this? Can you show me that number on your fingers? Can you count to that number with me? or other simple things. I also do this during the afternoon dismissal time that can take up to 15 minutes. I use them more as a transition activity to help reinforce what is being taught during class. I also go back and review them. I came up with this after seeing how many students come in knowing nothing about numbers.
For best results print on white card stock. Then glue another small piece of card stock on the back corner that will be whole punched. The extra piece will really help with the ware and tear on daily use. Then laminate on small laminator and whole punch and put on lanyard with book ring.
