Standard 1.0 Knowledge of Algebra, Patterns, and Functions: Students will algebraically represent, model, analyze, or solve mathematical or real-world problems involving patterns or functional relationships.
|
|
A. Patterns and Functions
|
1. Identify, describe, extend, and create numeric patterns
|
a. Represent and analyze numeric patterns using skip counting by 2, 5, and 10 starting with any whole number and using whole numbers to 100
|
b. Represent and analyze numeric patterns using skip counting backward by 10s starting with any 2-digit whole number
|
c. Recognize a function table as a relationship between numbers
|
d. Complete a function table with a given one-operation rule (+, -) using whole numbers
|
2. Identify, copy, describe, create, and extend nonnumeric patterns
|
a. Represent and analyze growing patterns that start at the beginning and show no more than 3 levels, and ask for the next level, using symbols, shapes, designs, and pictures
|
b. Represent and analyze repeating patterns using 3 different objects in the core of the pattern
|
c. Transfer a repeating pattern from one medium to 2 different media using no more than 3 different objects in the core of the pattern such as: red, green, red, green, ... A, B, A, B, ...  ,  , , , ...
|
|
B. Expressions, Equations, and Inequalities
|
1. Write and identify expressions
|
a. Represent numeric quantities using operational symbols (+, -) and whole numbers to 25
|
2. Identify, write, and solve equations and inequalities
|
a. Represent relationships using appropriate relational symbols (>, <, =) and operational symbols (+, -) with whole numbers to 100
|
b. Find the missing number (unknown) in a number sentence using operational symbols (+, -) with whole numbers up to 50
|
|
C. Numeric and Graphic Representations of Relationships
|
1. Locate points on a number line
|
a. Represent whole numbers up to 100 on a number line
