Cards are numbered 1-20 and as even and odd by color. They have 10 frames included to match the written number.
Use to teach kiddos 1 more 1 less with a matching/memory activity! Ex: Flip cards over into two separate piles, and pick up one card. The card reads the number 2. Students need to choose from the other pile and look for the "matching" number one more/less. In this round, the students need to find one more, which is the number 3.
Or use for your own games, be creative! Enjoy!
