I saw another teacher use this model for a worksheet, so I created and translated my own so that my Spanish speaking students could use it. It is a great way for students to visually see "10 partners". You could also have them reverse it for subtraction.
This is a cute activity for students to do on St. Patrick's Day / el dia de San Patricio. If you like this activity, please check out all the other St. Patrick's Day items I have available in my TpT store! :)
