Cyas practiced skip-counting backward from 200 by tens by filling in missing numbers. This activity helped Cyas recognize the pattern 200, 190, 180, and so on, while strengthening subtraction-by-10 skills and number-sequence fluency. Cyas also practiced identifying which number belonged in each blank based on the surrounding values. The task supported confidence with place value because the tens digit changed predictably as the numbers decreased.
Tips
Tips: Extend Cyas's learning by practicing forward and backward counting by 10s using a number line or hundreds chart. Invite Cyas to create a missing-number puzzle for someone else, then explain the pattern used. Use household objects grouped in tens to connect skip-counting with real quantities, and introduce counting by 5s or 2s when Cyas is ready.
