Counting in Tens & Hundreds

Lesson Planning of Counting in Tens & Hundreds

Subject Mathematics

Students` Learning Outcomes

• Count and write in 10s (e.g.10, 20, 30 ………….)
• Count and write in 100s (e.g. 100, 200 ……300)

Information for Teachers

• Counting in 10s is 10, 20, 30, 40, 50 …………
• Counting in 100s is 100, 200, 300, 400 ……..
• In counting in tens we just change the digit at tens place.
• In counting in 100s change the digit at hundreds place.

Material / Resources

Writing board, chalk / marker, duster, textbook

Introduction

• Write on the board: 2, 4, 6, 8, 10 ……………………..

Ask the students what kind of arrangement is it? (Counting in 2)

Write on the board: 5, 10, 15, 20 ………………

• Ask them what kind of arrangement is it? (Counting in 5)
• Now write on the board:
• 10, 20, 30, 40 …………………………………………

• Tell them that this is known as counting in Tens.
• Write on the board:
• 100, 200, 300, 400 …………………..
• This is counting in hundreds.

Development

Activity 1

• Write on the board counting from 1 to 10.
• Ask the students that how much gap you observe in counting from 1 to 10?
• Tell the students that if we put zero after in counting from 1 to 10 we will get counting in Tens.
• Tell the students that in counting of Tens we move 10 steps forward and in counting of hundreds we move 100 steps forward.
• Write on the board:

Activity 2

• Ask the students to observe it carefully.
• Explain them that in counting of 10s the digit at ones place remains the same whereas the digit at Tens place changes. Ask the students to count in 10s and fill in the missing numbers notebooks.

Activity 3

• Write on the board:
• Explain the students that in counting of 100s we have 3-digits.
• We fix the digit same at ones and tens place whereas the digit at hundreds place changes.
• Call the students to the board one by one and ask them to fill in the missing boxes.

Sum up / Conclusion

• Counting in 10s is ten steps forward.
• Counting in 100s is hundred steps forward.

Assessment

• Fill the boxes by counting in 10s.
• Fill in the boxes by counting in 100s.
