📝 Teacher Notes: Goals, Supports & Extensions

I can... statements:

- I can use A = πr² to find the area of a circle. - I can solve for radius or diameter when given area.

Success criteria:

- Substitute the correct radius into the formula. - Provide area with correct units. - Show clear steps or justification.

Differentiation strategies:

- Provide a formula card and worked example for students who need it. - Allow a calculator for computation or use π ≈ 3.14 as needed. - Pair multilingual/dyslexic-friendly instructions with a short oral explanation.

Extensions (advanced learners):

- Find area when given circumference. - Solve compound shapes that include semicircles or quarter circles.

Dyslexia-friendly reading options:

- Use larger font, increased line spacing, and simpler sentences. - Read problems aloud or provide audio versions. - Highlight key numbers and units in a different color.
