− | ===Name of the activity=== | + | Show children semicircle by drawing diameter.[[File:semicircle.gif|200px|right|link=http://karnatakaeducation.org.in/KOER/en/index.php/File:Semicircle.gif]] |
− | Brief blurb describing what the activity. If this has been borrowed from some external web site (for example, a non OER or OER site which had this idea and based on which the activity was developed)

| === Objectives === | | === Objectives === |
− | Content objectives - what content areas
| + | #A diameter divides the circle into two equal halves and each such half is a semicircle or hemicircle. |
− | | + | #Forming a semicircle by joining any two points on the circumference through its centre i.e. by drawing a diameter. |
− | Skill objectives - what specific skills
| |
− | | |
− | Classroom objectives - to demo peer learning, to make a classroom resource, etc -
| |
− | | |
− | All these kinds of objectives need not be there for every activity. And no need to list them as different headings. This is only for our reference when we are developing activities.

− | How to do the different steps of the activity?
| + | # Bring cut circles of different sizes. |
− | | + | # Fold them into exact halves. |
− | What kinds of questions you can ask for that activity
| + | # Recognise semicircles. Let them colour each half with different colour. |
− | | + | # Identify the centre, circumference, diameter and semicircle of the circle. |
− | What are the student follow-up activities/ questions you can give?
| + | # Fold circle into exact half. |
− | | + | # Draw diameter on folded line and colour each half with different colour. |
− | Categories: (Subject) (Topic) (Sub-concept/topic) (Class 6) (Resource format)
| + | *Evaluation |
− | | + | #Were the students able to draw and cut perfect circles? |
− | Example - (Mathematics) (Triangle) (Area) (Perimeter) (Class 6) (Class 8) (Geogebra) (Video)
| + | #Was the folded line (diameter) passing through the center of circle? |
| + | #In how many different ways can you draw semicircles for a given circle? |
