This Google Slides Activity includes 4 unique 6x5 tables in which students are asked to determine benchmark fractions - 50%, 25%, 10%, 5%, and 1%. The starting slide provides reminders for determining these benchmarks, and some answers are filled into table #1 to help students get started.
The last slide is labeled as a Challenge Slide and could be used to challenge gifted students or even assigned as extra credit.
I have used this activity in my 6th grade classroom and all abilities of students enjoyed the challenge. There is no prep required other than saving the activity to your Google Drive and assigning it via Google Classroom or providing your students with a link to the activity.
