This challenging worksheet flips skip counting around with backward patterns and tricky three-digit sequences. Multiple-choice items ask students to find the missing number in 30, 27, 24, ___, 18 and to extend 150, 140, 130, 120, ___, plus identify which option does NOT belong when counting by 3s from 0. Five fill-in-the-blanks include count-back chains like 24, 22, 20, ___ and 75, 70, 65, ___, along with a 180, 170, ___, 150 stretch into bigger numbers. Working both forward and backward across decades stretches second graders into the kind of flexible number sense that powers mental math and place value.
