Number Line

Oh, no! Half of the numbers are missing! But first graders can find all the missing numbers using number sense and comparing numbers skills on this number line worksheet.

Each line of this math worksheet features a series of numbers in order, but some of the numbers have been replaced with blank lines. Students will have to use their counting by ones and pattern recognition skills to determine which number belongs on each blank line. The numbers go up from 1-30 and even count backward from 20-10 in some cases.

If counting backward proves to be a challenge, give students more practice with the Practice Counting Backwards #1 worksheet.
