Angelik has three basketballs that all have the same mass. She knows that one basketball has a mass of 5 grams. To find out the mass of all of her basketballs, she adds them together:
5+5+5= 15 grams

The mass of the group is always EQUAL to the sum of each object or part.
The mass of the group is always LESS than the sum of each object or part.
The mass of the group is always MORE than the sum of each object or part.
The mass of the group is always GREATER than the sum of each object or part.
Jayden has a banana. He uses a balance and measures the mass of the banana to be 50 grams. Jayden cuts the banana into 5 pieces. He puts the 5 pieces on the balance.
