Math - [Lesson 5.1]

Teacher: Mr. Kovalik (408) 314-1092

Objective and Summary:
SWBAT represent how likely an event is to occur as a probability between 0 and 1
1

Rankings--Rank the following events on the scale below. Place the letter for each event on the appropriate place on the probability scale.

How likely is it that...
A. It rains more than 5 times this week in San Jose.
B. Somebody will call Ms. Paul "Ms. Pool" today.
C. You will do an exit ticket for math class today.
D. Mr. Mancini will pop up in one of your classes today.

CFS:
#1: Accurately places probabilities on the scale
#2: Explains placement with math evidence

Justify--Explain your reasoning for where you placed "C" on the probability scale.
"I placed C on the probability scale... because..."

Rankings 2--Rank the following events on the scale below. Place the letter for each event on the appropriate place on the probability scale. Be ready to share why.

How likely is it that...
A. You choose a white marble out of a bag that has 2 black marbles and 2 white marbles.
B. You buy a lottery ticket tomorrow and win the jackpot.
C. It is hotter than 60 degrees outside in June in San Jose.

Rankings--Rank the following events on the scale below. Place the letter for each event on the appropriate place on the probability scale. Be ready to share why.

The numbers 1 to 5 are written on small pieces of paper and placed in a bag. A piece of paper will be picked out at random.

How likely is it that...
A. You pick a 15.
B. You pick an odd number.
C. You pick any number greater than 1.
D. You pick the number 2.

CFS:
#1: Accurately places probabilities on the scale
#2: Explains placement with math evidence

Be Creative 1--Make your own example of an event that is half and half or has a 50% chance. Explain why it is a 50% chance.

CFS:
#1: Explains with math evidence

1

Be Creative 2--Make your own example of an event that is unlikely (around 1/4 or 25% chance). Explain why it is unlikely.

CFS:
#1: Explains with math evidence

If you have time... (optional)

Be Creative 3--Make your own example of an event with any probability, and tell me WHY it is impossible, unlikely, 50-50, likely, or certain.

Good work!

There are new probability skills on IXL's STARRED section. Try them out to deepen your understanding and also work ahead.

EXIT TICKET PART A

Rankings--Rank the following events on the scale below. Place the letter for each event on the appropriate place on the probability scale.

The numbers 1 to 10 are written on small pieces of paper and placed in a bag. A piece of paper will be picked out from the bag.

Part 1
How likely is it that...
A. A piece of paper with an even number is picked out.
B. A piece of paper with a 12 is picked out.
C. A piece of paper with a number other than 1 is picked out.

EXIT TICKET PART B

Justify--Explain your reasoning for where you placed "C" on the probability scale.

(A piece of paper with a number other than 1 is picked out)

"I placed C on the probability scale... because..."
