Students build counting and number-sequence fluency in this train-themed math activity. Learners fill in missing numbers on train cars, either by counting groups of objects or completing skip-counting patterns, with teachers able to adjust the counting range, sequence step, and whether distractor answers appear. This activity supports TEKS K.3.C (compose and decompose numbers).
Skills: counting, skip-counting, number sequencing, number recognition. Kindergarten-1st grade.
