Mr. Purle is putting together bags of supplies to pass out to the teachers at the beginning of the school year. Each bag will contain the supplies shown in the table.

Question

A table shows items for bags of supplies. There are 26 number 2 pencils in the bag, there are 14 red pens in the bag, and there are 52 erasers in the bag.

Part A
Write two equations to find the total number of items in each bag. Use the Associative Property of Addition to write the two equations



Part B
Write two equations to find the total number of items in each bag. Use the Commutative Property of Addition to write the two equations.

Answer 1

Part A:

Let x represent the total number of items in the bag.

Equation 1: 26 + (14 + 52) = x

This equation represents adding the number of pencils (26) to the sum of the number of red pens (14) and erasers (52) to get the total number of items in the bag.

Equation 2: (26 + 14) + 52 = x

This equation represents adding the sum of the number of pencils (26) and red pens (14) to the number of erasers (52) to get the total number of items in the bag.

Part B:

Equation 1: 26 + (14 + 52) = x

This equation is the same as in Part A, using the associative property of addition.

Equation 2: 52 + (26 + 14) = x

This equation represents adding the number of erasers (52) to the sum of the number of pencils (26) and red pens (14) to get the total number of items in the bag, using the commutative property of addition.
