Equally partition area, linear and set models
Brownies
Description Students use paper folding to partition a pan of brownies (a sheet of rectangular paper) into equal portions (first four, then eight, then ten) through a simple storyline told by the teacher. 

Mathematics Partitioning to make equalsized areas is a fundamental skill students need to build their understanding of fractions and area models. In this task, rather than use a ruler, students must find other ways to determine equal partitions and may discover paper folding is a key strategy. The ability to fold and consider both the number of folds as well as the regions created involves spatial reasoning and making predictions – both of which help students better understand fractions, proportions and how to equally partition area models.
