Identifying Patterns with Even and Odd Numbers Using an Addition Chart

This lesson teaches how to identify patterns using an addition chart. It explains the difference between even and odd numbers and demonstrates how to use an addition chart to find sums. The commutative property of addition is introduced, showing that the order of addends does not affect the sum. The video explores the results of adding even numbers, odd numbers, and a combination of both, highlighting patterns in the sums. Finally, it encourages using this knowledge to predict sums before calculating them.

How can you tell if a number is even?

• It is greater than 5.

• All objects have a partner.

• It has no partners.

• It ends with an odd digit.

What is the sum of 3 and 4 using an addition chart?

• 8

• 6

• 7

• 9

What does the commutative property of addition state?

• The sum is always even.

• The sum remains the same regardless of the order of addends.

• The sum changes if the order of addends changes.

• The sum is always odd.

What is the result when two odd numbers are added?

• An odd number

• A negative number

• An even number

• A prime number

What is the sum of an even number and an odd number?

• Always greater than 10

• Always odd

• Always even

• Always zero
