These are reproducible flashcards for increasing numeral fluency! The hearts just provide a fun, holiday themed way to increase student interest than just the typical black dotted ten frame.
You can copy additional pages to work on quantities and numbers from 11-30.
Subitizing, or recognizing quantities without having to count them all, is a huge push in the current common core trainings. These flashcards are a simple introduction to math/numeracy lessons!
These can also be used for fast and easy assessments at the end of lessons, i.e. ticket out the door. Enjoy!
