Can your students spot the number that's missing? It sounds simple, but filling in missing numbers builds real number sense.

These worksheets ask learners in Kindergarten through Grade 2 to complete number sequences by figuring out what comes before, after, or in between. You'll find counting by ones, skip counting by twos, fives, and tens, and sequences that count backward. They're great for morning work, fast finisher activities, or quick assessments. Teachers can use them to see exactly where a child loses track of a sequence. Parents can use them at the kitchen table for five minutes of focused practice. No prep needed.

  • Fill-in-the-blank sequences counting forward and backward
  • Skip counting practice for 2s, 5s, and 10s
  • Number line activities with missing values
  • Varied difficulty so you can match the right sheet to the right student
