This video tutorial teaches how to add numbers within 20 using the counting on method. It provides two examples: adding 8 plus 5 and 9 plus 6, using tens frames to visually demonstrate the process. The video emphasizes completing a tens frame and counting on to find the total sum.

What is the main concept introduced in this video?

• Multiplying within 20

• Adding within 20 by counting on

• Dividing within 20

• Subtracting within 20

What is the first step in the counting on method?

• Subtracting the numbers

• Multiplying the numbers

• Placing the initial number of counters

• Dividing the numbers
