Lesson Planning of Place Value of Digits

 

Lesson Planning of Place Value

Subject Mathematics

Grade 2nd

Students` Learning Outcomes

  • Recognize the place value of a 3-digit number.
  • Identify the place value of specific digit in a 3-digit number.

Information for Teachers

  • A number with 3-digit is known as a 3-digit number.

 

  • A 3-digit number has 3 place values i.e. ones, tens and hundreds.

Place Value of Digits

  • An abacus is the one of the first counting device. It is a wooden/plastic framed tools with beads used to inculcate place value concept in children since childhood.

 

 

Material / Resources

Writing board, chalk / marker, duster, textbook, abacus, place value chart of hundred (100)

Introduction

  • Tell the students 1 more than 99 are 100.
  • We read it as one hundred.
  • 99 is a 2-digit number.

 

  • 100 is the smallest 3-digit number.
  • It has 3 place values i.e. ones, tens and hundreds.
  • Hang the place value for number 100 in front of class.

 

  • Explain the students that we start writing the place value from right hand side and moves to the left i.e. ones, tens, hundreds

Development

Activity 1

  • Show your class an abacus and inform the students that we are going to see the number 100 on abacus.
  • Call one student and ask him to put one red bead in hundred rods.
  • Tell the students that there is no bead in ones and tens rod.
  • There is one bead in the hundreds rod.
  • It shows 1 hundred, 0 Tens and 0 Ones.
  • It makes the number hundred (100)
  • Tell that students that similarity we can show 110 on abacus.

 

  • Call one student and ask him to put one bead in hundreds and Tens rod.
  • Ask students that 1 hundred, 1 Tens and 0 Ones makes which number? (110)
  • Repeat this activity with different numbers and encourage the students.

 

Activity 2

  • Write any 3-digits number on the board.
  • Ask the students how many digits it has? (3)

 

  • Ask them can they tell the place value of digit 7? (Ones)
  • Explain the students that to identify the place value of a specific digit we take help from the place value chart.
  • Like if we put 104 in the place value chart.

 

  • We start reading any 3-digits number from left hand side.
  • The first digit from right represents ones.
  • The second digit from right represents tens.
  • The third digit from right represents hundreds.
  • So the place value of digit 4 in number 104 is Ones.
  • Write different 3-digits numbers on the board and ask the students place value of any specific digits.

 

Sum up / Conclusion

  • 3-digits number has following place values Ones, Tens, Hundreds.
  • We can identify the place value of a specific digit in any 3-digit number by putting it in place value chart.

Assessment

  • Make pictures of abacus on the board and ask the students to write the 3-digit number with the help of beads, sown on abacus.

Tick the correct  place value of shaded number. 

 

Follow up

  • What is the place value of digit 1 in 1000?

 

  • Put 1000 in place chart.
  • Ask the students to solve the questions given in their textbook.
