Students learn how to divide a quantity into two or more parts when given a ratio. As learning progresses students link sharing to a ratio with known geometrical facts such as the perimeter, area and the angles in a quadrilateral.
The start of the lesson recaps writing and simplifying a ratio. At the end of the lesson students are given a more problem solving question to develop their mathematical reasoning skills.
Differentiated Learning Objectives
- All students should be able to share to a ratio where the total shares are a factor of the amount.
- Most students should be able to share to a ratio by calculating the value of a single share.
- Some students should be able derive and simplify a ratio involving three terms and share to any amount.
