  • Students will be able to identify and differentiate between fat and thin objects.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they know what 'big' and 'small' mean. Show them two objects of different sizes (e.g., a big book and a small book). Introduce the terms 'tall,' 'short,' 'fat,' and 'thin' similarly, using real-world examples.
  • Video Viewing (5 mins)
    Play the YouTube video: 'Learn Grade 1 - Maths - Big and Small tall and short fat and thin'. Encourage students to watch carefully and identify the different objects being compared.
  • Discussion (5 mins)
    After the video, ask students what they saw in the video. Ask them to give examples of big and small, tall and short, and fat and thin things from their own environment. Reinforce the vocabulary.
  • Activity: Comparing Objects (10 mins)
    Divide students into small groups. Provide each group with a collection of objects (e.g., pencils, erasers, blocks). Ask them to compare the objects based on size, using the terms 'big,' 'small,' 'tall,' 'short,' 'fat,' and 'thin.' Have each group share their findings with the class.
  • Worksheet (10 mins)
    Distribute a worksheet with pictures of different objects. Ask students to circle the big object, put an X on the small object, draw a line under the tall object, and color the short object. They should also be able to identify fat and thin objects.

Interactive Exercises

  • Classroom Comparison
    Have students compare themselves to each other: 'Who is taller? Who is shorter? Is your pencil fat or thin?'
