Mental Strategies for Adding Multiples of 10
Learning to add multiples of 10 mentally is a crucial step in building strong number sense and prepares you for more complex multi-digit addition.
 

1. Thinking in Tens (Place Value)
   Ignore the zeros for a moment and focus on the tens digits.
   Add those single digits together.
   Put a zero back at the end of your sum.
   Example: 40 + 30
   Think: “What is 4 + 3?"
   The answer is 7.
   Add a zero back: 70.
   So, 40 + 30 = 70
   
   
2. Counting by Tens (Number Line)
   This method is a direct extension of the “Count On” strategy, using jumps of ten. It’s helpful for visualizing the addition.
   How it works:
   Start with the first number in your head.
   Count on by tens the number of times indicated by the tens digit of the second number.
   Example: 50 + 30
   Start at 50.
   Count on three tens: 60, 70, 80.
   So, 50 + 30 = 80.
   
    
   

By practicing these mental strategies, you’ll find yourself quickly and accurately adding multiples of 10 without needing to write anything down.
