Building
upon knowledge and skills gained in preceding
grades,
by the end of Grade 2, students will:
Standard 4.4
(Data
Analysis, Probability, and Discrete Mathematics)
All students will develop spatial sense and the
ability to use geometric properties, relationships,
and measurement to model, describe and analyze
phenomena.
Standard 4.4.2.A
Data
Analysis
Standard 4.4.2.A.1
Collect,
generate, record, and organize data in response
to questions, claims, or curiosity.
· Data collected from students’ everyday
experiences
· Data generated from chance devices, such
as spinners and dice
Standard 4.4.2.A.2
Read,
interpret, construct, and analyze displays
of data.
Standard 4.4.2.A.3
Pictures,
tally chart, pictograph, bar graph, Venn diagram
Standard 4.4.2.A.4
Smallest
to largest, most frequent (mode)
Standard 4.4.2.B
Probability
Standard 4.4.2.B.1
Use
chance devices like spinners and dice to explore
concepts of probability.
· Certain, impossible
· More likely, less likely, equally likely
Standard 4.4.2.B.2
Provide probability of specific outcomes.
· Probability of getting specific outcome
when coin is tossed, when die is rolled, when
spinner is spun (e.g., if spinner has five equal sectors,
then probability of getting a particular sector
is one out of five)
· When picking a marble from a bag with three
red marbles and four blue marbles, the probability
of getting a red marble is three out of seven
Standard 4.4.2.C
Discrete
Mathematics-Systematic Listing and Counting
Standard 4.4.2.C.1
Sort
and classify objects according to attributes.
· Venn diagrams
Standard 4.4.2.C.2
Generate
all possibilities in simple counting situations
(e.g., all outfits involving two shirts and three
pants).
Standard 4.4.2.D
Discrete
Mathematics–Vertex-Edge Graphs and Algorithms
Standard 4.4.2.D.1
Follow simple sets of directions (e.g., from
one location to another, or from a recipe).
Standard 4.4.2.D.2
Color
simple maps with a small number of colors.
Standard 4.4.2.D.3
Play
simple two-person games (e.g., tic-tac-toe) and
informally explore the idea of what the outcome
should be.
Standard 4.4.2.D.4
Explore
concrete models of vertex-edge graphs (e.g. vertices
as "islands" and edges as "bridges").
· Paths from one vertex to another
