Term

triple balance beam measurement

 

 

 

   

Definition

Step 1 - Record weight amounts from large to small.

 

Step 2  - Line up the decimals and arrange as an addition problem.

 

Step 3 - Add the three amounts together.

 

Step 4 - Round the numbers by least significant figures.

 

 

Step 5 - Add the measurement units

  

Term
