It addresses Common Core State Standards:
K.CC.5 Given a number from 1-20, count out that many objects.
It is tiered to meet the readiness levels of early learners and those who need the challenge of bigger numbers to keep them engaged. It is also self-correcting so students can use it independently. For student just starting out with number recognition use the single tens frame and game cards 0-10. For students who are ready to be challenged beyond those numbers, offer game cards 0-20.
Teachers: Copy off all materials and laminate. Cut apart the game cards and fold on the dotted line. Secure the flap with a paperclip or clothes pin. Students may use this activity independently as they practice producing numbers or as a game with each child having a building mat. One child selects a card and shows that other students the number without saying it. The first students to produce the number correctly on their mat, gets to keep the playing. Play until all the cards are won and then count them up to see who is the Top Apple Ten Frame Builder.
