Presentation Transcript

### CRCTMath Blitz!

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.

Team 4

Team 1

Team 2

Team 3

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.
- If other team members shout out or provide answers their team loses a point.

Team 4

Team 1

Team 2

Team 3

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.
- 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.

Team 4

Team 1

Team 2

Team 3

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!

Suzy and Joe run around a circular track. They start at the same time. Suzy takes 9 minutes to run the entire track. Joe takes 15 minutes to run the entire loop. They want to know how many minutes it will be before they are at the same place and time.

Should they find the GCF or LCM of the 2 numbers?

LCM

What does same time. Suzy takes 9 minutes to run the entire track. Joe takes 15 minutes to run the entire loop. They want to know how many minutes it will be before they are at the same place and time.SOAR stand for?

(same – opposite – and reciprocal)

What is 10% of 50? same time. Suzy takes 9 minutes to run the entire track. Joe takes 15 minutes to run the entire loop. They want to know how many minutes it will be before they are at the same place and time.
