The purpose of this activity is for students to match situations and expressions and then answer the questions asked about the situations. The numbers used in the problems are deliberately chosen so that students cannot make the matches just by looking at the numbers.  This sorting task gives students opportunities to analyze situations and expressions closely and make connections (MP2, MP7). Students will use what they notice about the connections between division situations and expressions when they write their own situations in the next activity.

• Invite students to share the matches they made and how they know those cards go together.
• Attend to the language that students use to describe their matches, giving them opportunities to describe the kind of division happening in the situation more precisely.
• Highlight the use of terms that reference the number of equal groups and the size of the group.

The purpose of this activity is for students to write situations involving division of a whole number by a unit fraction and division of a unit fraction by a whole number. Students may use one of the contexts from the stories in the previous activity, changing the quantities, or they may make up their own. Consider having a Gallery Walk for students to see the variety of story problems.

• Invite students to share problems or have a Gallery Walk.
