Practice numbers in the teens (11-20) with the simple small or whole group game. Students are given an activity sheet. During their turn, they draw a card, call the number on that card to the group and place it face up in the discard pile. All students find the number called and trace it. Repeat until all cards have been drawn and called. Extension: After tracing the number called, have children write the number on a wipe board for independent practice.
