This set of cards includes numeral, word, and dot cards for numbers 1 through 30. They are perfect for use in a pocket chart for whole group discussions and games as well as independent center work. To make a self-checking center, simply print on cardstock, cut out, and write the numeral on the back of the dot and/or word cards. This is also helpful for easily organizing the cards when you put them away. My second graders loved organizing them for me at the end of center time! Another option for whole group use is to show a card and have students write the other two ways to represent the number on dry erase boards. It’s great for a quick assessment!
