Probability
Designed
by: Sally Hug, Hand Middle School
GRADE
LEVEL: 8th SUBJECT(S):
Math
CORE
CURRICULUM OBJECTIVE(S): Determine the
number of possible events that could occur in a
probability experiment and the probability of an
outcome. (8SP2-3)
RESTATEMENT:
Students will find probability of given events.
OVERVIEW:
Students will find the probability of certain
events using concrete objects by picking shapes
from a bag and using spinners.
FOCUS/
ESSENTIAL QUESTION(S): What procedures are
followed to find probability? How can
probability be found using given events?
TIME
FRAME: One 45-50 minute period - one period
for a hands-on activity
RESOURCES:
- Gateways to Algebra and Geometry (p.23-24),
for reference - Data gathering sheet - Rubric -
Paper/ Pencil - Pattern blocks - Overhead -
Overhead pens - Overhead spinners - Sandwich
bags
ASSESSMENT:
Students will find probability of given events
using concrete objects; such as, drawing pattern
blocks from a bag, and spinning spinners.
INSTRUCTIONAL
ACTIVITIES:
ACTIVITY
ONE
*
The students will review probability. Using the
overhead spinners, the teacher will label the
parts of the spinners using whole, counting
numbers (1, 2, 3, 4...).
*
The teacher will ask questions and the students
will write answers on their own paper.
"What would be the probability of the
spinner landing on a 2? What would the
probability of the spinner landing on an even
number?, on an odd number?, a multiple of two?,
a factor of four?"
*
The teacher will go over and review the answers
with the students to check for understanding.
ACTIVITY
TWO
*
The students will review probability. The
teacher will pass out the data gathering
probability sheets. The students will work the
first one or two together with the teacher and
then complete the sheet independently.
*
Students will also create their own probability
questions and find the answers.
*
The teacher will monitor students.
*
Chart will be displayed in hallway or in
classroom.

Probability:
Use your bag of pattern blocks to find the
probability of choosing the items below. First
fill in the types an number of each pattern
block that you have in your bag. Place the
probability in the form of reduced fraction.
