What is it: This is a worksheet on finding and explaining addition patterns on an addition table.
Target/Topic: Addition Patterns, Even/Odd
Standard: 3.OA.9 dentify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.
Strength:
-clear and precise explanation of the arithmetic patterns
Limitation:
-The standard includes multiplication patterns but this only deals with addition patterns on a very small scale.
