Core Concept: Students learn to use parentheses to group operations that must be performed first. Key Skills: Title: The Polygon Protocol Subject: Lesson 32, Homework

Step 1: Add the fractions first: ( \frac25 + \frac35 = \frac55 = 1 ).
Step 2: Add the whole number from Step 1 to the original whole number: ( 1 + 1 = 2 ).
Answer: ( 2 ) Fractions: 2/6 + 5/6 = 7/6 = 1

Borrowing/Regrouping: The biggest hurdle for 4th graders in this lesson is understanding that they are "borrowing" from a whole number, similar to multi-digit subtraction, but in fractional units.

1. Fractions: 2/6 + 5/6 = 7/6 = 1 1/6
2. Whole numbers: 4 + 3 = 7
3. Total: 7 + 1 1/6 = 8 1/6 Answer: 8 1/6

• Step 1: Same denominator? No (4 and 3 → LCD = 12).
• Step 2: Rename: ( \frac14 = \frac312 ), ( \frac23 = \frac812 ).
• Step 3: Add fractions: ( \frac312 + \frac812 = \frac1112 ).
• Step 4: Add whole numbers: ( 2 + 3 = 5 ).
• Step 5: Answer: ( 5\frac1112 ).
