Task# Number Line Up

Illustrative MathematicsVaries

The first time students do this activity, the teacher may have to lead students through by actually saying, 'who has 1, who has 2, who has 3,' and so forth, but doing this once helps students understand what is needed and they will be able to work together as a group without much direction. If a group really struggles, try working with a smaller group and a fewer number of cards. Or divide the class into two teams and give each team an identical set of cards, numbered 1 to 11 (for a class of 22) if the class isn't ready to deal with numbers up to 20. It may be worth a class discussion about efficient approaches students use to line up.
