Bullseye Math
The object of this math game is for students to use problem solving strategies and math reasoning skills to make bull’s eyes.
Materials:
Per Group of Students 1 Deck of Cards numbers 0 to 9 only 1 Die—6 sided
Procedures:
1. Place cards deck is face down after shuffling
2. One student rolls the die to determine the target range (see table)
3. Students take the top 4 cards from deck
4. They use the cards to use any function and combination of numbers to find an answer that fits within the target range.
5. If the student’s answer falls within the target range, then he/she hits a bull’s eye and wins.
6. Each player plays five times and the one with the most wins, wins the game.
Example:
Die = 2
Cards 4, 7, 5, 2
7 2 (4 x 5 ) = 980
Variations:
Multiplication Bull’s-eye
Division Bull’s-eye
Fraction Bull’s-eye
Decimal Bull’s-eye
Addition Bull’s-eye
Algebra Bull’s-eye
Bull’s Eye Table:
Number on Die Target Range
1 000 - 500
2 501 - 1500
3 1501 - 3000
4 3001 - 4500
5 4501 - 6000
6 6001 - Higher

I am starting a new section that will be posted every Sunday - it is called the “Week in Review - the Top 5.” These are the top five posts visited during the past week my visitors to this blog.
I would like to thank all the subscribers to my Teach Science and Math Newsletter, new subscribers this week, and all those who visit and find the information useful.
Another week is about to begin and the following are the here are the Top 5:

NASA is preparing to go back to the moon after almost 40 years. This time to stay for months at a time, with the intention of using the moon as springboard for sending men and women to Mars and other space exploration.
Now NASA is wondering what the effects are on the human body, since the moon’s gravitational pull is 1/6 th of earths gravitational pull on the human body.
In view of NASA’s decision to go back to the moon, have you wondered what it is like to stand on the moon?
Almost everyone learns about the gravitational pull of the moon being 1/6 th that of earth; however, what does that really mean?
In mathematical terms, a person who weighs 120 pounds on earth would weigh 20 pounds on the moon.
So now that we have done the math, how can someone simulate this when they are on earth and not on the moon?
NASA being the ingenious people they are have determined that if someone lies in bed at a 9.5 degree angle, the body feels the effects of being on the moon and its 1/6 th gravitational pull.
Try it
Lift one end of your bed so that it is tilted at exactly 9.5 degrees.
Now lie in your bed with your head at the high end and your feet at the bottom, resting on a board.
Your body will slid down until it places the exact amount of weight on your feet that is equal to the gravitational pull of the moon.
Now here is the catch, lie in this position for 90 days!
This is the only way to experience the gravitational pull astronauts will feel being on the moon for 90 days at a time.
Reality
You may only want to try this for a few hours or maybe a day.
The effects on the body after 90 days include weak muscles, loss of bone density, and inability to tolerate the gravitational pull of earth without physical therapy.
However, you can gain a sense of what it is like to stand on the moon for a few hours.
