Online Set Game


Rules

The object of the game is to identify a 'Set' of three cards from 12 cards laid out on the table. Each card has a variation of the following four features:
1) COLOR: Each card is red, green, or blue.
2) SYMBOL: Each card contains ovals, squiggles, or diamonds.
3) NUMBER: Each card has one, two, or three symbols.
4) SHADING: Each card is solid, open, or striped. 
A 'Set' consists of three cards in which each feature is EITHER the same on each card OR is different on each card. That is to say, any feature in the 'Set' of three cards is either common to all three cards or is different on each card.

Examples of sets:

1) color: different on each card, symbol: the same on each card (oval), number: the same on each (two),shading: the same on each card (solid)
oval solid blue 2
oval solid blue 2  
oval solid red 2
oval solid red 2  
oval solid green 2
oval solid green 2  
2) color: different on each card, symbol: different on each card, number: different on each card, shading: different on each card
diamond striped blue 2
diamond striped blue 2  
squiggle solid red 1  oval open green 3
oval open green 3
oval open green 3  
3) color: the same on each card (green), symbol: the same on each card (diamond), number: different on each card, shading: different on each card
diamond solid green 2
diamond solid green 2  
diamond striped green 3
diamond striped green 3
diamond striped green 3  
diamond open green 1

Positive and negative numbers on a number line

ATN Problem 1.4 In the Chips

How can you use a chip model to represent addition and subtraction?

In this investigation, we will be using chips to represent positive and negative integers. 

You may have heard the terms, "In the red" (meaning you owe or have a negative amount of money) and "In the black"(meaning have a positive amount of money)

In the image above, there are black positive chips and red negative chips on the board. Some red and black chips have already been put together in "zero pairs" that cancel each other out. Is this image "in the black" or "In the red"? How do you know?

Now try for yourself:

Inv 3.3 - Polystrip and quadrilaterals

Focus Questions: 
1. What combination of side lengths can be used to make a quadrilateral.
2. How many different shapes are possible a set of side lengths.  


Since the virtual polystrips can only got up to ten, use these number sets in place of the ones given in Problem A:
1.  3, 5, 8, 8
2.  2, 3, 5, 10
3.  8, 8, 10, 10
4.  6, 10, 3, 5
5. try your own!

Hint - Use the attach button seen below to link polystrips and allow them to move.

Investigation 3.1 - Building Triangles

Focus Question:  
What combination of three side lengths can be used to make a triangle?


Additional questions:  
  • Are there special conditions for the side lengths of a triangle?  
  • Can a triangle be built with any three side lengths?  Explain.

Investigation 2.2 - any polygon angle sum

Focus Question: What is the angle sum of any polygon with n sides?

Helpful site:
Math is Fun - Polygon angles



Application problem of understanding triangle angles.


Investigation 2.1 - Regular Polygons angle and angle sum formulas

The focus question is: What is the size of each angle and the sum of all angles in a regular polygon with n sides?

The students will review what is important in a polygon and how regular and irregular polygons compare.  The goal is for students to develop formulas the sum of interior angles for a polygon of n sides.


S - Sum of all angles
S = 180 (n - 2)  
when n = any number of sides of a polygon


A - measure of one angle
A = 180 (n - 2)/ n
OR  
A = 180 - 360/n   
when n = any number of sides of a polygon

Investigation 1.2 - Shapes and Designs

Focus Question: What are some common benchmark angles? 

Today students looked at the question, "What are some of the benchmark angles?"

Students were exposed to vocabulary words such as:
  • acute
  • obtuse
  • initial side
  • terminal side
  • degrees
  • right angle 
  • straight angle

We ended by playing a connect four game.  Lets see if our students can defeat their parents!
