This medium worksheet keeps the same shape as the first medium sheet but rotates in fresh numbers across the 120 range. Kids fill in nine sequences such as 10, 12, 14, ___, 18 for the 2s, 15, 20, 25, 30, ___ for the 5s, and the high-end runs 90, 100, 110, ___ and 70, 80, 90, 100, ___ to push the 10s right up to the topic ceiling.
Part B closes with a four-row matching activity pairing Count by 10s from 50 with 60, 70, 80, Count by 5s from 75 with 80, 85, 90, and Count by 2s from 22 with 24, 26, 28. Repeated exposure with new starting points helps first graders generalize the rule rather than memorize one chain.
