What you need:
•
•
•
•
a scorekeeper
4-5 marker boards (or page protectors)
markers
erasers/paper towel/socks, etc.
The questions rotate through the 10 units in 6th
grade math. There are 60 total questions.
Allow approximately 30 seconds for
responses.
Instructions for Teachers
• This is intended to be fast-paced quick answer
type game, not heavy on calculations. Recall of
important info from this year…
• Suggested use is to place students in 4-5 teams.
• You will need a whiteboard/marker for each
Team 4
Team 2
Team 3
Team
1
team.
Instructions for Teachers
• The first person in each team answers question 1
on their marker board. All correct responses
earn a point for
their
team.
Team 4
Team 2
Team 3
Team 1
• If other team members shout out or provide
answers their team loses a point.
Instructions for Teachers
• If none of the people get it correct, play shifts to the
next row of students on each team to see if they
can answer the question.
Team 1
Team 2
Team 3
Team 4
• The next question is answered by the next group of
students. Students can either shift positions (like a
relay) or just pass the marker board back.
Alternate Method:
• for a smaller group, arrange students in a
circle
• only 1 person answers each question
• If a student answers a question wrong they sit
down
• Last person standing, wins!

A friend suggests this game:
Roll a dice…
If the number is prime, he wins.
If the number is composite, you win.
Explain why this is not a FAIR game.
He has 4 chances of winning (1,2,3, & 5)
You only have 2 chances (4 and 6).
To be fair, the outcomes must be equally likely.
