 Identify and classify numbers into different types. 

 Apply simple methods to recognize and differentiate number types through engaging activities.  

 

 

 

 

 

 Concepts 

 

 

 Number types help categorize numbers based on their properties:  

 

 Natural Numbers: Counting numbers starting from 1 (1, 2, 3...)  

 Whole Numbers: Natural numbers including 0 (0, 1, 2, 3...)  

 Even Numbers: Numbers divisible by 2 (0, 2, 4...)  

 Odd Numbers: Numbers not divisible by 2 (1, 3, 5…)  

 

 

 

 

 

 Materials Required  

 

 

 

 Board & Chalk 

 Number flashcards 

 Number line 

 Colored markers

 Session Duration 

 

 90 minutes 

 

 

 

 

 Introduction  Activity (10 minutes):  

 Number sorting challenge  

 Place number flashcards (1–50) in a basket. Students pick one card at a time and run to the correct labelled section (Natural, Whole, Even, or Odd) on the classroom walls.  The Teacher checks their placement and facilitates a brief discussion to reinforce understanding. 

 Main Activity (65 minutes): 

 Number Grid Hope (20 minutes)  

 

 Draw a large 1–100 number grid on the floor.  

 Call out number properties (e.g., "Step on an even number!" or "Find a number that is whole but not natural!")  

 Students respond by hopping on the correct numbers.  

 Discuss each response and reinforce definitions.  

 

 Number Bingo (25 minutes) 

 

 Prepare Bingo cards with a mix of number types. 

 Call out clues like "An odd number under 20" or "A natural number that’s also even." 

 Students mark the correct numbers on their cards.  

 The first to complete a row shouts "Bingo!" and explains their answers.
