This is a set of 30 task cards which practice the skill writing equations that include and unknown number or variable. This set doesn't ask the student to solve for the variable. Thye are simply writing equations by replacing the "some number" with a variable.
These cards can be used as a SCOOT game, in small group centers, or as as independent activity.
These are a part of a series of task cards. Please see my other sets to understand the progression of this concept.
