Standard 3.PR.1 - Analyze the sequence of increasing subtraction sentences. Find the missing equation that completes the sequence.

Included Skills:

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.

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.
