Objective:
- Able to understand/reinforce the base-10 structure of the number system using the FLU model
- Able to recall the concepts of bidi(units), hattu(tens), nuru(hundreds)
- Able to analyze how numbers can be represented using the FLU model and correlate the representation to the H-T-U representation
Materials:
Materials:
small empty chits.
Process:
Demonstration:
- Ask students if they are familiar with the concept of place value and to explain what they understand of it using some examples
- Take few example numbers and discuss the nooru-hattu-biDi representation
- Next project the Geogebra file and demonstrate the representation of numbers using the F-L-U model and explain how it corresponds to the nooru-hattu-biDi representation
- Start with single digit numbers and then take up numbers >10 represented just using the unit blocks. Use the ‘put together’ option to show how 10 unit blocks can be grouped to form a long or a ‘rod’.
- Ask for students to give some numbers <100, come to the screen and explain how it should be represented
- Next take up numbers having more than 10 rods/longs and explain how the ‘put together’ option can be used again to group them into a ‘flat’
- Reiterate that whenever there is more than 10 of a kind (small blocks/rods) they must be grouped together and exchanged for a rod/flat
- Make sure to take up examples such as X0, X0X, X00 (X = 1-9)
- After having demonstrated number representation using the Geogebra tool, use the blackboard to show how the representation can be done similarly on paper using dots for units, standing lines for rods and squares for hundreds. Demonstrate the same examples on the board.
