| + | ===Objectives=== |
| + | #To visualize the meeting point of lines/rays forms an angle |
| + | #Understanding the use of protractor to measure angle |
| + | #Familiar with the angle formation |
| + | #Get to know about classification of angles |
| + | ===Estimated Time=== |
| + | 90 minutes |
| | | |
| + | 10 - 15 minutes : previous class worksheet discussion |
| + | |
| + | 60 minutes : Discussion on Angle formation, measuring and types of angles. |
| + | |
| + | 10 -15 minutes : Refreshment activity (related to language) |
| + | ===Prerequisites/Instructions, prior preparations, if any=== |
| + | Prior understanding of points, Lines, rays and segment concepts |
| + | ===Materials/ Resources needed=== |
| + | *Digital : Computer, Geogebra application, projector. |
| + | *Non-digital : Worksheet and pencil. |
| + | ===Process (How to do the activity)=== |
| + | '''Teachers work:''' |
| + | |
| + | demonstration to |
| + | #Helps to identify intersecting lines (two or more) meet only at one point always and also can cross each other at a common vertex (which is the point of intersection). |
| + | #Angle formation using sticks and in Geogebra and also labelling it - Hands-on activity (children can use two sticks to understand about angle formation) - To help students to identify the angle formation in real life |
| + | #How to measure an angle using protractor |
| + | - Help to recognize the type of angle |
| + | |
| + | '''Students work:''' |
| + | |
| + | -Identify and give some examples where they will see angles formation in our surroundings |
| + | |
| + | -Using 2 sticks they have to observe angle formation and measure it using protractor |
| + | |
| + | -Using Geogebra plot and name an angle |
| + | |
| + | -draw different types of angles in notebook and label it :Acute, Obtuse, Right, Complete and Straight angle. |
| + | ===Developmental Questions:=== |
| + | #When two segments are joined at a point how many angles are formed? |
| + | #How many angles are formed when two lines crossing each other? |
| + | #How you name label and name the angles? |
| + | # |
| + | #What is the convention used to measure angles? |
| + | #Does the angle depend on the segment length? |
| + | #What are the different types of angles? |
| + | ===Refreshment activity:=== |
| + | '''Tongue twisters(ನಾಲಿಗೆ ನುಲಿಗಳು)game''' |
| + | |
| + | Ask students to read the '''tongue twisters''' aloud. Then ask them to read anyone again but faster. Then ask them to read as fast as they can 10 times. |
