**In teams of 4, students solve problems including operations of rational numbers.
**Topics include: evaluating expressions by substitution, multiplying & dividing
integers, operations with rational numbers, additive inverse, equivalent fractions &
decimals, & representing addition of integers on a number line.
**Each member of a team solves 1 problem, then passes it back to the next person,
etc., until all 4 problems have been answered. One student brings their answer
sheet to the teacher to be checked. A team continues on to the next topic if all
answers are correct. If a problem or multiple problems are incorrect, the teacher
lets the students know incorrect answers. Students may then collaborate to find
and correct student mistakes until they achieve all correct answers, in which they
may proceed to the next topic.
