This math topic focuses on the skill of skip counting downward by single digits and predicting the next two numbers in a sequence. It includes various problems where students need to continue skip counting by 2, 3, or 4 to identify the missing numbers in a sequence. Each problem provides a sequence with two missing numbers at the end, and multiple-choice answers are given for students to select the correct continuation of the sequence. This activity is part of a broader unit aimed at enhancing number sense.
