Pattern Rules

Unit 6: Patterns

Today I will identify rules for numeric patterns using my knowledge of addition, subtraction, and multiplication. 

So that I can make predictions about important numbers in my life. 

I’ll know I have it when I can complete a patterns Quizziz activity with 4/4 correct solutions

What is a pattern?

Patterns

Predictable behaviors in numbers, objects, people, etc.

In math, we think of patterns in numeric lists, visual representations, shapes, and contextual problems where something is growing or shrinking in a consistent way.

Visual patterns can represent growing patterns. Assess how they are growing to predict what would come next!​

Concrete / Pictorial Patterns

Labelling

Match the rule to the pattern image:

Drag labels to their correct position on the image

Add 4

Add 2

A list of numbers that grows in a particular and consistent way (following a RULE)

Numeric Patterns

​Addition Rule Example: m + 3
3, 6, 9, 12, 15, __, __


Subtraction Example: d - 5
62, 57, 52, 47, 42, __, __


Multiplication Example: p x 2
18, 36, 72, 144, __,

Growing Addition Example:
10, 20, 35, 55, 80, __, __

Input/Output tables track the results of pattern rules based on what the starting numbers and results are.
The numbers in an input/output table MUST follow the same rules
