Grade 3 - Patterns and Relations
Standard 3.PR.1 - Analyze the sequence of increasing addition sentences. Find the missing equation that completes the sequence.
Included Skills: Number Patterns, Addition
Demonstrate an understanding of increasing patterns by: • describing numerical (numbers to 1000) and non-numerical patterns using manipulatives, diagrams, sounds and actions. • extending numerical (numbers to 1000) and non-numerical patterns using manipulatives, diagrams, sounds and actions. • comparing numerical (numbers to 1000) and non-numerical patterns using manipulatives, diagrams, sounds and actions. • creating numerical (numbers to 1000) and non-numerical patterns using manipulatives, diagrams, sounds and actions. • Describe a given increasing pattern by stating a pattern rule that includes the starting point and a description of how the pattern continues; e.g., for 42, 44, 46 the pattern rule is start at 42 and add 2 each time. • Identify the pattern rule of a given increasing pattern, and extend the pattern for the next three terms. • Identify and explain errors in a given increasing pattern. • Locate and describe various increasing patterns found on a hundred chart, such as horizontal, vertical and diagonal patterns. • Compare numeric patterns of counting by 2s, 5s, 10s, 25s and 100s. • Create a concrete, pictorial or symbolic representation of an increasing pattern for a given pattern rule. • Create a concrete, pictorial or symbolic increasing pattern; and describe the relationship, using a pattern rule. • Solve a given problem, using increasing patterns. • Identify and describe increasing patterns in the environment. • Identify and apply a pattern rule to determine missing elements for a given pattern. • Describe the strategy used to determine missing elements in a given increasing pattern.
