------ Note: The Information above this point will not be sent to your printer --------

 Follow these steps as shown in the example below: Read the question and look at the "sandwich". Color in the missing rod and write its number to complete the "sandwich". Read the question again and fill in the missing numbers to complete the equation. 1 2 3 4 5 6 7 8 9 10 What number added to 6 makes 9? 9 6  9 3 + 6 = 9

What number added to 4 makes 8? 8 4 8

8 = 4 + 4

What is the difference between 10 and 6? 10 6 10

4 = 10 - 6

What do you have to add to 5 to make 9? 9 5 9

5 + 4 = 9

What do you subtract from 6 to leave 2? 6 2 6

2 = 6 - 4

Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
