To count fluently forwards and backwards up to 20 and 30, and skip count by twos.
Have children count in unison to 20 or 30 and back. For a more challenging activity, have children count up by twos in unison. You might want to reinforce this activity by pointing to each even number on a number line or a yardstick as children count aloud by twos.
Part 1 has children count in unison from 0 to 20 and then backwards to 0. Part 2 moves to counting 0 to 30 and then backwards to 0. The extension challenges children to count by twos to 20 (or 30).
Count from 0 to 20 and then backwards to 0.
While children are enjoying their building of mastery, feel free to repeat. When children are eager for more, try Part 2.
Count from 0 to 30 and then backwards to 0.
As always, when children seem excited for a new challenge, move on.
Count from 0 to 20 (or 30) by twos.
