G4.3M.C1.PO.2. Explain the rule for a given number sequence, verify that the rule works, and use the rule to make predictions.
FIND THE RULE TO THE PATTERNS
1, 2, 3/ 1, 2, 3/ 1, 2, 3/ 1, 2, 3/ …
AABB, AACC, AADD, AAEE…, __BB, __CC, __DD, __EE, __FF, __GG
1 12 23 3
HOW TO FIND RULES OF A PATTERN
Rule 1: Is the pattern sequence increasing or decreasing.
Rule 2: Figure out what the pattern is? adding, subtracting, or multiply?
Rule 3: Identify the rule
FINDING RULES…
1. Is the pattern sequence increasing or decreasing.
1, 3, 5, 7 , 9, __, __Pattern is increasing; adding.
FINDING RULES
2. Figure out what the pattern is… adding, subtracting, or multiplying?
1, 3, 5, 7, 9, __Adding. 1 + __=3, 3 + __=5, 5 + __=7, 7 + __=9
FINDING RULES…
3. Identify the rule1, 3, 5, 7, 9, __
Adding 2 to each number1+2=3, 3+2=5, 5+2=7, 7+2=9, 9+2= __
FIND THE RULE
2,5, 11, 23, __
Rule 1: increasing or decreasing
Rule 2: adding, subtracting, or multiplying?
2x2=4+1=5
5x2=10+1=11
11x2=22+1=23,
What is the rule? Multiply by 2 then add 1
USE THE RULES TO HELP YOU
Rule 1: Is the pattern sequence increasing or decreasing.
Rule 2: Figure out what the pattern is… adding, subtracting, or multiply?
Rule 3: Identify the rule
