Internet resources. Students collect data using objects, pictures, and
Explore one-to-one counting and the concept of votes by making a survey of
Us and Them
In this lesson, students collect data, generate bar graphs, and compare
two data sets. They also consider whether a given category is likely,
certain, or impossible in each of the data sets.
Students investigate oranges to find out if oranges have the same number
of slices. They also investigate the fractional part of an orange.
Sticks and Stones
In this Illuminations lesson, students play \"Sticks and Stones,\" a game
based on the Apache game \"Throw Sticks,\" which was played at
multi-nation celebrations. Students collect data and investigate the
likelihood of various moves.
Children work in groups using colour spinners to make predictions
Rescue Mission Game
In this lesson, students play a game to learn about the four forces of
flight: lift, drag, thrust, and gravity. Before playing the game, students
conduct a probability experiment with spinners and record their results in
tally tables and bar graphs.
In this lesson, by flipping coins and pulling marbles out of a bag,
students begin to develop a basic understanding of probabilities, how they
Tootsie Pop Pull - Probability
This lesson is an introduction to probability and the work of sampling
In this lesson, the multiplication model Cross Products of Sets is
introduced. While not commonly presented as a model for multiplication, it
will prove useful to children when they solve probability problems in
which they must determine all possible outcomes.
Fair or Unfair-Introduction to Probability
This lesson introduces the idea of probability theory. Students will use
everyday experiences and intuitive understanding to gain an understanding
In this Unit Plan, students explore the many meanings of multiplication
(skip counting, repeated addition, sets, arrays, number lines, cross
products of sets, and balanced equations).
Through teacher guidance, students will experiment with objects to
generate probable outcomes to consider probability.
This unit of two lessons, from Illuminations, focuses on combinations, a
subject related to the probability-and-statistics strand of mathematics.
Students conduct surveys and represent data in a variety of ways. They
also find and compare measures of center.
Survey of Hair and Eye Colors
In the following lesson, students participate in activities in which they
focus on the uses of numbers. The activities explore how students use
numbers in school and every day settings as a way for students and the
teacher to get to know each other at the beginning of the school year.
In this three-lesson unit, from Illuminations, students gather, represent,
and interpret data about pizza choices.
In this lesson, from Illuminations, students look at attributes that vary
from roller coaster to roller coaster, attributes that make each scream
machine uniquely thrilling.
A Tale of Two Stories
The following activities are inspired by children\'s natural curiosity
about fantasy and fairy tales. Specifically, the investigations focus on
developing the process of classification, especially an awareness of
similarities and differences.
In this investigation, students will analyze data collected by themselves
and other students.
Students will predict the pocket at which the ball will stop and how many
hits will occur.
In this lesson, from Illuminations, students explore the relationship
between theoretical and experimental probabilities. They use an
interactive \"box model\" that allows them to simulate standard
The Game of SKUNK: Choice and Chance in Life
In this lesson, from Illuminations, students practice decision-making
skills while playing a dice game called \"Skunk.\"
Spin, Toss, and Roll
Students will use hands-on experiments to find the probability that
certain events will occur.
Explorations with Chance
In this lesson, students analyze the fairness of certain games by
examining the probabilities of the outcomes.
This lesson plan presents an activity which demonstrates the birthday
paradox, using it as a springboard into a unit on probability.
Monty's Dilemma: Should You Stick or Switch?
This lesson, from Illuminations, presents a version of a classic game-show
scenario. You pick one of three doors in hopes of winning the prize.
Grid and Percent It
In this lesson, students use a 10 × 10 grid as a model for solving various
types of percent problems.
In this activity, students identify and classify polygons according to
various attributes. Extensions to fundamental ideas about probability and
statistics are also included.
