Key Concepts

  • Counting from 40 to 49 in ascending and descending order.
  • Understanding tens and units (ones) in numbers 40 to 49.
  • Identifying the number that comes before, after, or between given numbers.

Learning Objectives

  • Students will be able to count forward and backward from 40 to 49.
  • Students will be able to identify the number of tens and ones in numbers 40 to 49.
  • Students will be able to determine the numbers that come before, after, or between numbers in the range of 40 to 49.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing numbers 1-39. Ask students to count aloud as a class. Introduce the numbers 40-49 and explain that today they will learn to count and understand these numbers.
  • Video Viewing (7 mins)
    Play the YouTube video 'Learn Grade 1 Maths Practicing Numbers 40 to 49 | Learning Video For Kids | Kids Classroom'. Pause the video at key points (e.g., when counting in ascending/descending order, when representing numbers as tens and units) to ask questions and ensure understanding.
  • Counting Practice (8 mins)
    Practice counting from 40 to 49 as a class. Then, have students take turns counting individually. Focus on both ascending and descending order.
  • Tens and Units Activity (10 mins)
    Use manipulatives (e.g., blocks, counters) to represent the numbers 40-49. For example, show 47 as 4 groups of ten blocks and 7 individual blocks. Ask students to create their own representations.
  • Number Sequencing Game (10 mins)
    Write numbers 40-49 on index cards. Give each student a card and have them line up in ascending order. Then, have them line up in descending order. Next, remove some cards and have students fill in the missing numbers.

Interactive Exercises

  • Number Line Fill-In
    Provide students with a number line from 40-49 with some numbers missing. Have them fill in the blanks.
  • Counting Objects
    Provide students with groups of objects (e.g., crayons, stickers) ranging from 40-49. Have them count the objects and write the number.
  • Tens and Ones Match
    Create cards with numbers (40-49) and corresponding cards showing the tens and ones (e.g., '4 tens, 3 ones'). Students match the numbers to the correct tens and ones representation.

Discussion Questions
