Key Concepts

  • Place Value (Tens and Ones)
  • Comparing Numbers
  • Greater Than, Less Than, Equal To Symbols (>, <, =)

Learning Objectives

  • Students will be able to identify the tens and ones place in a two-digit number.
  • Students will be able to compare two two-digit numbers based on the value of their tens and ones places.
  • Students will be able to correctly use the greater than (>), less than (<), and equal to (=) symbols to represent the comparison between two numbers.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing the concept of place value (tens and ones). Ask students to identify the tens and ones place in various numbers (e.g., 23, 41, 68). Briefly introduce the greater than, less than, and equal to symbols.
  • Video Viewing (7 mins)
    Play the Kids Academy video 'Comparing Numbers 1st Grade'. Encourage students to pay attention to how the teacher compares numbers using place value.
  • Guided Practice (10 mins)
    After the video, work through a few examples together on the board. For example, compare 35 and 27. Ask: 'How many tens in 35? How many tens in 27? Which number has more tens?' Emphasize the importance of starting with the tens place and moving to the ones place only if the tens are the same.
  • Worksheet Activity (10 mins)
    Distribute a worksheet with number comparison problems, similar to the baseball math worksheet shown in the video. Have students independently compare the numbers and circle the correct symbol (>, <, =).
  • Review and Wrap-up (3 mins)
    Review the worksheet answers as a class. Address any remaining questions or misconceptions. Summarize the key steps for comparing numbers.

Interactive Exercises

  • Number Line Comparison
    Create a number line on the board (or use a large printed one). Call out two numbers and have students point to them on the number line. Ask which number is further to the right (the greater number).
  • Symbol Cards
    Give each student a set of cards with the >, <, and = symbols. Write two numbers on the board and have students hold up the correct symbol card to show the comparison.
