Looking for a new way to pair up students? These slips are a fun and easy way to mix up your students for partner work and to reinforce rounding skills. One slip gives an actual number and asks students to round to a given place (tens, hundreds, or thousands); a second slip gives the rounded number. I've used this to mix up seating for Morning Meeting; we then went around the circle so each pair shared their actual number and rounded number. The document includes 19 pairs of rounding cards.
These cards can also be used as an easy center; just glue the actual number slip and rounded number slip to opposite sides of an index card and laminate for students to practice their rounding skills.
