Graph- a visual way to show how two sets of numbers relate to each other.
Relationship- a pattern formed by two sets of numbers.
1 right 3 up
^^^ That is an equation...
3c + 2
3(4) + 2
3 x 4 = 12
12+2= 14*
* over all marbles
________
Now try to answer this:
4 x + 3
x= 3
Answer:
Table of Values- a table showing two sets of related numbers
Table:
how many squares in figure # 60?
Answer is 60= 121
x2+1 is the expression
2(60)+1=121
2f+1= s
^^f= figure
model the expression
2y + 4 with cups and counters
then show if:
y= 1
y= 3
y=1
2y + 4=
2(1) + 4=
2+4=
6=6
y= 3
2y + 4=
2(3)+4=
6+4=
10=10

Need more practice??? HERE are some games to help you on probability...have fun!
Organizing Outcomes
1st way chart or table
Independent events- the outcome of one event has no effect on the outcome of another event.
Sample space- all possible outcomes of an experiment.
For example:
The question in the class is: A coin is flipped and a 6 sided die is rolled. These 2 events are called independent outcomes.
a.) Use a table or chart and list all the possible outcomes...
Second way to organize outcomes
Tree diagrams- a diagram used to organize outcomes contains a branch for each possible outcome of an event.

1.Estimate 6.6 divided by 2.3
6 divided by 2 = 3 > The answer e.) Front- end estimation
Front-end estimation is the highest place value when estimating.
2. (The picture shown in the booklet) Estimate 6.6 divided by 2 = 3
6 divided by 2 = 3 underestimate
8 divided by 2 = 4 overestimate
The answer is a.) Number line estimation
Number line estimation is when you use number line on estimating.
3. [C] 25.73 [ divided by] 3.1 [=] 8.3
24 divided by 3 = 8
27 divided by 3= 9
The estimate suggest an answer between 8 and 9. The answer 8.3 is reasonable.
The answer is b.) Estimate, then use a calculator
4. Divide 20.4 divided by 3.
(The picture shown in the booklet) <3>
<3>
21 divided by 3 = 7
The answer is around 7. The decimal point goes between the 6 and 8.
The answer for this question is c.) Divided as whole numbers, then estimate to place the decimal
A.) turning a knob to a open door
The answer is Rotation.
The answer is because if you try to do it in real life, you will notice that the door knob will turn either counterclockwise or clockwise same as the rotation. The rotation will depend on the degrees it will rotate. It either rotate on 90, 180, 360 and etc.
