In this lesson, students explore partitioning into fractional parts by dividing sandwiches among different sized groups of students. During exploration, students consider different ways that sandwiches can be decomposed so that children in the groups have an equal amount. Students compare the amounts of sandwiches each person gets and explore equality among fractions through class discussion.
In this lesson students decompose, add, and subtraction fractions with a focus on unit fractions.
Scenario
You and a friend enter a fishing contest. You have been asked to collect worms before you can move to the next round in the fishing contest.
