Posted on by FaSMEd
Lesson Plan: A concept development lesson about using properties to determine the quadrilateral.
| Subject: | Mathematics. |
|---|---|
| Age of students: | 14-15 years. |
| Non-digital Technology: | Small and big cards Mini whiteboards. |
| Functionalities of Technology: | Sending and displaying. |
| Time needed: | 60-90 minutes. |
| FaSMEd Partner: | The African Institute for Mathematical Sciences Schools Enrichment Centre. |
Summary:
This lesson is first about using properties of quadrilaterals to identify particular shapes and second about identifying the smallest number of properties needed to define a shape. After a short introduction, during which the teacher asks students to give the properties of a square, the students work in small groups. They are given strips of small cards; on each strip properties of a given quadrilateral are given. Students sketch the quadrilateral and later determine the smallest number of properties needed to define the quadrilateral. After the activity the teacher holds a class discussion aiming to go over the answers and elicit something about the students’ understanding.
