    1st Grade Game-Based Math Lesson Comparing Numbers

    1st Grade Game-Based Math Lesson Comparing Numbers

    Overview

    This is a game-based learning math lesson for 1st grade that deepens conceptual understanding of comparing two two-digit numbers and has students use the symbols associated with comparison (>, =, <).

    Summary

    This is a game-based learning math lesson for 1st grade that deepens conceptual understanding of comparing two two-digit numbers and has students use the symbols associated with comparison (>, =, <).

    • Time frame (Three 20-30 minute sessions)  
      • Day 1: Introduce & explore  
      • Day 2: Practice new skills with partner gameplay.
      • Day 3: Refine skills with individual gamified assessment.
    • Format (face-to-face, virtual)

    Background for Teachers

    • Understand the symbol > means greater than.
    • Understand the symbol < means less than.
    • Understand the symbol = means equal to or the same as.
    • The following song may be used to review the concept of place value and build a conceptual understanding of tens and ones in preparation for students to compare two-digit numbers.
    • The following song may be used to extend the learning about comparing two-digit numbers.

     

    Step 1 - Goals and Outcomes

    Learning Intentions:

    • Students will be able to understand that two-digit numbers are compared by looking at the tens and ones of each number. 

    Success Criteria:

    • Students will use the >, =, and < symbols to compare two-digit numbers.

    Step 2 - Planning Instruction

    Student Background Knowledge

    • Prior to this lesson, students will need to understand that two-digit numbers represent the number of tens and ones.
    • Students will also need to be familiar with the concept of less than, equal to, and more than since these words will now be associated with math symbols <, =, and >.

    Materials

    • Alligator Math Activity Mats (printable from themeasuredmom.com)
    • Printable two-digit number bug cards.
    • Random Number Generator App, physical number two-digit number tiles in a bag, or printable number tiles.
    • Assessment Game Recording Sheet

     

    Step 3 - Instruction

    • Day 1:  Introduce & Explore
      • Sing a Song:  Place Value Song (sung to Mary Had a Little Lamb) by Tessa from talesfromoutsidetheclassroom.com
        • This song reviews the concept of place value and the students' conceptual understanding of tens and ones in preparation for students to compare two-digit numbers.
      • Introduce the Inequality Math Symbols that represent the words greater than (>), equal to (=), and less than (<).
        • Show two plates of candies with 19 and 10.  Have students visualize and use words to tell you about the candies.  Which plate has more?  Which plate has less?  Connect the words to the symbols.  Count the candies on each plate and write 19 > 10 on the board.  Practice reading the inequality together.
      • Sing a Song: My Alligator Goes Chomp (sung to The Wheels on the Bus)
      • Explore with Base 10 Blocks & Bug Battle Visuals
        • Display the bug battle visuals
        • Have students record the numbers for each bug on their individual whiteboard.  
        • Build each bug's number with base 10 blocks to support conceptual understanding of which number is greater. 
        • Practice writing >, =, or <  and read the inequality together.
    • Day 2:  Practice New Skills
      • Review one of the bug battle visuals from yesterday. 
      • ​​​​​​​Play a Partner Game:  Bug Battles
        • Pair students and have each partnership get an Alligator Greater Than Mat. (printable from themeasuredmom.com)
        • Scatter the two-digit bug cards around the room.
        • Students each choose a bug from around the room and bring it back to their battle mat.  
        • On the count of three, each student reveals his/her bug card and compares the numbers.
        • Students place the bugs on the Alligator Greater Than Mat in the correct place to make the inequality sentence true so the alligator eats the greater number.  
        • Partners read the inequality sentence together.  
        • The student with the greater number wins.
        • The students return their bugs and repeat.
        • Switch partners after 5 minutes.

    Step 4 - Assessments

    • Day 3: Refine skills
      • Individual Game Greater Than, Less Than Assessment
        • Use a random generator app to gamify the individual assessment. Set number range between 10-100.
        • Alternatively, use a bag or hat with number tiles for the students to draw from.

    Use the attached rubric for evaluating the Greater Than Less Than Assessment Game.
