👩‍🏫 Teacher Notes & Differentiation Strategies

Support for ESL Students:

• Provide vocabulary cards: "denominator," "numerator," "common," "subtract"

• Use sentence frames: "First, I find the LCD by ___. Then I convert ___."

• Pair with bilingual buddy for explanation tasks

Support for ASD Students:

• Break tasks into clear steps with visual cues

• Provide fraction strip manipulatives for visual support

• Use consistent colour coding (denominators in blue, numerators in red)

Support for ADHD Students:

• Allow movement breaks between sections

• Provide fidget tools during independent work

• Chunk problems: complete 2-3 questions, then check progress

Extension Activities:

• Challenge: Create your own word problem involving fraction subtraction

• Investigate: What happens when you subtract a larger fraction from a smaller one?

Assessment Focus:

• Can students find LCD correctly?

• Do they convert fractions accurately before subtracting?

• Can they explain their reasoning clearly?
