Add and subtract fractions with like denominators using models and symbols
The Relay Race
Description Students are introduced to the concept of a relay race where participants complete various fractional distances of the total. Based on two known fractional distances of a race with unlike denominators, students will determine the distances that the other runners might complete. 

Mathematics Students benefit from multiple opportunities to compose and/or decompose fractions with unlike denominators, using models and symbols. This supports them in developing fraction number sense, intuitive understanding of the operations of addition and subtraction and expands their repertoire of strategies.
