Task# The Stamp Collection

Illustrative MathematicsVaries

This task uses language, 'half of the stamps', that students in Grade 5 will come to associate with multiplication by the fraction 1/2. In Grade 3, many students will understand half of 120 to mean the number obtained by dividing 120 by 2. For students who are unfamiliar with this language the task provides a preparation for the later understanding that a fraction of a quantity is that fraction times the quantity.
