Key Concepts

  • Counting from 80 to 89
  • Ascending order (smallest to largest)
  • Descending order (largest to smallest)
  • Place Value - Understanding tens and ones

Learning Objectives

  • Students will be able to count forward and backward from 80 to 89.
  • Students will be able to arrange numbers from 80 to 89 in ascending and descending order.
  • Students will be able to identify missing numbers in a sequence from 80 to 89.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing numbers 1-79 with the students. Then, introduce the concept of counting from 80 to 89. Show the YouTube video: 'Learn Grade 1 Maths Practicing 80 to 89 | Learning Video | Kids Classroom'.
  • Ascending and Descending Order (10 mins)
    Explain what ascending (smallest to largest) and descending (largest to smallest) order mean. Use examples with smaller numbers first (e.g., 1-5) before moving to 80-89. Write the numbers 80-89 on the board in ascending order, then erase them and have the students say them in ascending order. Repeat for descending order.
  • Missing Numbers Activity (10 mins)
    Present a series of number sequences with missing numbers within the 80-89 range. For example: 80, __, 82, __, 84. Have students fill in the missing numbers. Start with easier sequences and gradually increase the difficulty.
  • Tens and Ones (5 mins)
    Reinforce that 80 is 8 tens and 0 ones. Have students identify the number of tens and ones in each number 81-89 (e.g., 83 is 8 tens and 3 ones).
  • Wrap-up (5 mins)
    Review the key concepts covered in the lesson. Ask students what they learned and answer any questions they may have.

Interactive Exercises

  • Number Line Activity
    Create a number line from 80 to 89 on the floor using tape or chalk. Have students take turns standing on different numbers and then jumping to the next or previous number.
  • Ordering Game
    Write the numbers 80 to 89 on individual cards. Mix the cards up and have students work together to arrange them in ascending or descending order.
  • Place Value Blocks
    Using base ten blocks, have students represent the numbers 80 to 89 and identify the tens and ones place.
