Lesson Planning of Introduction to Geometry

Subject Mathematics

Grade 5^{th}

Students` Learning Outcomes

- Know instruments of a geometry box (pencil, Straight edge ruler, set squares and protractor)

Information for Teachers

- Protractor: This is a protractor. It is used to measure angles.

- Note: how it has the shape of half a circle; therefore it only measures angles up to 180.
- It has two sets of numbers: one set goes from 0 to 180 one way, one set from 0 to 180 the other way.
- A Divider: A divider, also known as a measuring compass, is a mathematical or drafting instruments of the length of irregular lines and of distances on maps or charts.

- Set Square: Set Squares are useful for drawing parallel lines and perpendicular lines.

- Compass: A device known as a compass (or pair of compasses) is used by mathematicians and craftsmen in geometry to draw or inscribe or arc.

- A Ruler: A ruler is used to measure length of a straight line. It has centimeter and millimetre scales on it.

Material / Resources

Writing board, chalk / marker, duster, geometry box, textbook

Introduction

- Divide the class into groups with mixed ability.

- Ask them to open their geometry boxes and guess about its usage. (10 min)
- Take each group`s feedback and then introduce the correct use, write the name and one sentence for each on board.
- Rearrange their seats.
- Development

Activity 1

- Repeat the uses with students once again.

- Erase the board and give them time to write on copies about each of the tools.
- Peer checking (they will check each other`s work and do corrections)
- Ask them to close their note books and ready for the game “Who am I?”(Expected answer would be as; Set Square)

- (For the first time teacher can conduct it but later students can also forward the question statement, such as;
- Statement: My one side is ‘L’ shaped, I am empty from middle and I have a friend also, who am I? (Expected answer would be as; Compass)

Sum up / Conclusion

- Conclude the lesson in brief to introduce the instruments of the geometry box.

Assessment

- Q- A Session
- Who am I? as explained above.
- Draw a table in their notebooks with one line introduction about each
