India/Knowledge Base/Maths/Numbers and Operations/SWBAT identify the size of different place values
Prerequisite: K.1 Vocab [unit, tens and hundreds]
K2: number of digits in unit, tens and hundreds.
Prerequisite. S.1. SWBAT identify a number as either a hundred or tens or units by visual inspection.
T writes a number on the board and then checks with S if they have prerequisite knowledge of assigning place value to the number. Once that is checked, T will call three students up to the front and give them 1, 2 and 3 ice-cream sticks respectively and then ask them to turn their backs to the class.
Introduction of New Material (INM)
Visual: T will ask the student holding 1 stick to turn around and then T writes a single digit number on the board and tells students that a unit number has only 1-digit. Similarly, T asks the S with 2 ice-cream sticks to turn around and then T writes a number with tens digit (2-digit) on the board and will tell the students that a tens digit number has 2-digits. Then T writes a hundreds (3-digit number) on the board and ask the third S to turn around and tell the students that a hundreds digit number has three digits.
CFU for class: T writes three pairs of numbers on the board. Each S tells his partner which is units, tens or hundreds number based on the number of digits.
Guided Practice (GP)
In the groups of two, the S will do the following:
Q1. Tell the number of digits in the following numbers:
Q2. Tell your partner if the following is a units number or tens number or a hundred number:
Students will answer the following questions on their own:
Q.1 How many digits in a units number?
Q2 How many digits are there in a hundreds number?
Q3. Write if the following is a Unit, Tens or Hundreds number:
Each group will write a unit, tens and hundreds number on the notebook and hold it up for T to see.
