All you need is an empty can and some pennies (or other small objects)
I have students close their eyes while I drop pennies into the can one at a time. Afterward I see who knows how many I dropped. I change it up by dropping 2 or more at a time for skip counting and sometimes we start with some pennies already in the can to 'count-on'.
I've posted a free printable in my store so you can jazz up your can if you wish :) You can download it HERE.
If you have other ideas for using the listening can I'd love to hear them :)
I know that this will become a go-to activity for your class!!
