Number Patterns

In this video, Orrin helps his dad paint patterns on his bedroom wall using colors and numbers. He learns to create sequences with addition and subtraction, discovering rules for number patterns. The video emphasizes the importance of double-checking work and encourages creativity in learning math concepts.

What colors did Orrin use for his first pattern?

• Green and Purple

• Blue and Red

• Red and Green

• Yellow and Blue

What was the rule Orrin discovered for the sequence 2, 4, 6, 8?

• Multiply by 2

• Add 1

• Add 3

• Add 2

How did Orrin determine the rule for the sequence 10, 20, 30, 40?

• By subtracting 5

• By adding 10

• By multiplying by 2

• By dividing by 2

What did Orrin learn about adding 10 to a number?

• The units digit changes

• The number doubles

• The tens digit decreases by one

• The tens digit increases by one

What is the pattern rule for the sequence Orrin created for his dad: 45, 40, 35, 30?

• Add 5

• Add 10

• Subtract 5

• Subtract 10

What mistake did Orrin make in his sequence starting with 15?

• He added instead of subtracted

• He subtracted 2 instead of 3

• He ended with 1 instead of 0

• He started with the wrong number

What was the final corrected sequence Orrin created using the rule 'subtract 3'?

• 15, 14, 13, 12, 11, 10

• 15, 12, 9, 6, 3, 0

• 15, 13, 11, 9, 7, 5
