Note
Questions 7 and 8 can be omitted 
since they go into further depth 
than is necessary for Grade 5.
Create a class set of mathematical single-variable 
expressions and corresponding scenarios. Post the 
expressions around the room and give each student a 
description of a situation. Have them match their description with the 
corresponding expression.
Extension: Students could create a bank of stories and corresponding 
expressions for classmates to match.
