– Identify objects around us that have two-dimensional shapes like squares, circles, rectangles, and triangles.

Importance:
– We’ll learn why these shapes are important in industries like Textile, Engineering, and Architecture.
– We’ll relate shapes to real-life things, like squares on a chessboard, circles like coins, rectangles for doors, and triangles for caution signs.
– We’ll also see how these shapes are used in everyday objects at home and in real-life situations.

So, get ready to explore shapes and numbers today!

 

Counting Skill:

  1. Counting Numbers 🧮: We’ll learn to count numbers from 231 to 240. 🌟 Example: 231, 232, 233, 234, 235, 236, 237, 238, 239, 240.
  2. Skip Counting 🏃‍♀️🏃‍♂️: We’ll skip count in 2s, 5s, and 10s. Example: For counting by 2s – 2, 4, 6, 8, 10… For counting by 5s – 5, 10, 15, 20, 25… For counting by 10s – 10, 20, 30, 40, 50…

Writing Skill:

  1. Writing Numbers ✍️: We will practice writing numbers neatly. Example: Write the number 237 on your paper.
  2. Recognizing Lines 📏: We’ll identify curved lines and straight lines. Example: 🔄 Curved line – like the shape of a banana 🍌 ↔️ Straight line – like the edge of a book 📚
  3. Describing Shapes 🔵🔶: We’ll describe different shapes and figures. Example:
    • 🔲 Square – has four equal sides, like a chessboard.
    • ⭕ Circle – is round, like a coin or a wheel.
    • 🟩 Rectangle – has two long sides and two short sides, like a door.
    • ▲ Triangle – has three sides, like a caution sign.

Remember, practicing is the key to getting better at counting and writing! 🚀✨
