Hook:
Quick warm-up:
Write on the board:
½ + ½ = ?
¾ – ¼ = ?
Discuss how these are straightforward because the denominators are the same.
Mini Lesson:
Model with visuals or on the board:
Let's look at adding/subtracting with the SAME DENOMINATOR...
⅗ + ⅖ = (add numerators, keep denominator)
Reminder= 5/5 = 1
Why don't we add the denominator?
Let's look at adding/subtracting with the DIFFERENT DENOMINATOR...
⅔ + ¼ - Why can't we simply add the numerators?
We MUST have the SAME DENOMINATOR to add/subtract.
Step 1: Find common denominator (e.g., 12) - what number are both of these factors of?
Step 2: Convert: What ever you do to the bottom... you must do to the top.
⅔ = 8/12, ¼ = 3/12
Step 3: Then you can ADD and SUBTRACT numerators
Guided Practice: Whiteboards

Reflection
Ask: "What do we do first when the denominators are different?"
Quick ticket out the door: ⅔ + ⅖ = ?
