Here is a fun way to practice missing numbers 1-20 on a number line. 20 task cards are included that feature a number line with one missing number. Students find a card around the room (or at a center if you don't roam the room). Next they determine the missing number and write it next to the matching letter on the recording sheet. The cards could also be used to a game of scoot or laminated and used to write on with a dry erase marker.
