Learning Objectives Students will be able to :

• B u i l d f u n d a m e n t a l k n owl e d g e to explore the concept of shapes in the future classes
• Recognize the shapes around them
• Develop the ability of reasoning to solve problems

Appreciate  the  different  dimensions of mathematical shapes

Major Concepts: Introduction to Shapes

Learning Resources:

• PPT
• Worksheets
• Cardboard Shapes
• China Clay
• Activity Sheet
• Videos

ENGAGE:

Teacher Initiative: Teacher starts with a coloring activity in which the teacher asks the students to color real life objects in the activity sheet.

The second activity is a tracing activity. In this activity teacher displays some real objects and asks the students to trace it in a white paper. Example:   Match   box,  coin,

eraser, etc.

Student Initiatives:  Students color the objects and trace the objects in given activity sheet.

Assessment: Teacher ensures that all student are participating.

EXPLORE :

Teacher Initiative: During the coloring activity of the engage stage, students   would   have   come  across

difference objects and their images. At the explore stage, teacher can ask the students to group the objects into similar shapes. The teacher will aid this process by drawing the shapes on the boards without naming them.

Teacher gives children flash cards of different objects and ask them to

sort it according to their shapes.

Student Activities: Students draw pictures of what they see in the board and group it based on the similarity in shapes. For example, they place all the   triangle  shaped objects in one group.

Assessment: Check each students under- standing of shapes.

EXPLAIN:

Teacher Initiative: At this stage, teacher asks the Student to articulate their understanding of different shapes. And teacher may notice that some children are struggling at a few places. Teacher can address those issues through a discussion and dialogue.

The following videos and  presentations will aid the teacher at this stage.

1. The teacher shows the video and  asks the students to watch it carefully. https://www.youtube.com/watch?v=eUazfCkQq84
2. The  Teacher  shows  a   v ideo  that d e p i c t   s      d i f f e r e n    t         s h a p e s . https://www.youtube.com/watch?V=boEJBYwHod4

Teacher shows a presentation related to shapes and asks them to say similar things that they see in their day-to-day life. Teacher checks their understanding by asking probing questions like, 'What do you see in this song?' 'Have you ever seen these shapes?' 'Where do you see these shapes?' 'What is the shape of clock?' etc. Here, the teacher also asks students to work as a group to identify different shapes and group the similar shapes.

Now the teacher introduces the names of the shapes which students have grouped (using PPT/ classroom activity)

Example:

Square

Triangle

Student initiatives:

• Students will listen and enjoy the song.
• Students will tell names  of objects they see in their daily life.
• Students will observe the PPT and group various shapes.

Assessment: Teacher checks student understanding on different shapes by asking about the objects around their environment.

ELABORATE:

Teacher shows or draws on the board some shapes and asks the students to sort similar shapes irrespective of their sizes.

Teacher asks the students to make shapes using china clay. Then, teacher asks the students to join the similar shapes.

Teacher shows some picture to the students and ask them to draw the same shape in their note book. Teacher can also ask them to color and count the shapes or use flash cards.

Student initiatives

• Students participate in the hands on activity.
• Students group objects of similar shapes.
• Students apply their knowledge about shapes through the activity.

Students relate the shapes with day to-day life.

Assessment: Teacher assesses student understanding on shapes through clay and flashcards activity.

EVALUATE:

Teacher initiative: Teacher gives the activity sheet to evaluate the students. Teacher asks students to color each shape in a different color.

Student initiatives: Students will do the activity. This may be done at school or at home.

Assessment: The activity sheet will help assess students' understanding on shapes and ability to color each shape in a different color.
