Angles not Angels…Angles not Angels!

Today some groups looked at the different types of angles there are and their special names.

We looked at right angles, actute angles, obtuse angles and straight angles.

Right angles are 90 degrees, actute angles are less than 90 degrees, obtuse angles are greater than 90 degrees and straight angles are 180 degrees.

We had a go making angles using our hands and arms. Can you guess what type of angles we have made?

Greedy Pig! (Newton Math Workshop)

The goal of the game is to score the most points possible.  Points are scored by rolling a single die.  Each time the die is rolled, you must add the number on the die to the sum of your previous rolls.  A player can roll the die as many times as they wish.  However, if a 1 is rolled, the player’s score goes to zero.  If this happens, you become known as a “greedy pig.”  Whenever you are happy with your score, you may choose to stop.

We used a 10 sided die to play with the number 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. As a group we found out that the probability of rolling a one was an equal likely chance because all ten numbers had the same chance of being rolled which was 1/10. We also worked out that it is unlikely for us to roll a one because there a 1/10 chance of rolling a one and a 9/10 chance of not rolling a one.

After the first round Liam was on the lead with 75 points, after the second round Liam was still in the lead with 95 points but in the third round everyone was knocked out for being “greedy pigs” except Joshua V on a score of 46 and Corey won with a score 64.

Lots of us were disgruntled by the rules of Greedy Pig so in pairs we came up with different ways we could adjust the game. Here are our ideas below:

Finlay & Ali: “Roll a certain number twice AND then everyone is out. So you get a life saver the first time the number is rolled and then you’re out the second time it is rolled.”

Nick & Blanca: “If you roll an odd number you’re out and if you roll an even number you can add it onto your score.”

Arun: “Rolling an even number gets you out and you can add an odd numbers which are rolled.”

Adam “If any two numbers are rolled twice, one after the other, then you’re a greedy pig.”

Tiffany: Changing the number to 0, because you can’t add zero to your score anyway.”

We had another go at playing Greedy Pig and each time we changed the rules to one of the adjusted rules suggested above.

 

Which suggestion do you think is the most fair way of playing Greedy Pig? Do you have another way we could change the rules to Greedy Pig?
