Step 1:
I'll solve this problem step by step, using the guidelines you specified:

Step 2:
: Understand the Problem

To find factor pairs of 30, we'll use a systematic approach with 30 pennies. A factor pair consists of two numbers that, when multiplied together, equal 30.

Step 3:
: Arrange the Pennies

We'll start by creating different rectangular arrangements using the 30 pennies to represent the factor pairs.

Step 4:
: List Possible Arrangements

- $$5 \times 6$$: 5 rows of 6 pennies, or 6 rows of 5 pennies
Let's systematically list out all possible rectangular arrangements:

Step 5:
: Identify Factor Pairs

- $$5 \times 6
From these arrangements, we can identify the factor pairs:

Final Answer

- (1, 30) - (2, 15) - (3, 10) - (5, 6) Note: This method provides a visual and tactile way to understand factor pairs by physically arranging the pennies into rectangular groups.
