Key Concepts

  • Counting to 120
  • Grouping by tens
  • Place value (tens and ones)

Learning Objectives

  • Students will be able to count objects up to 120.
  • Students will be able to group objects into sets of ten to aid counting.
  • Students will be able to identify the number of tens and ones in a two-digit number.

Educator Instructions

  • Introduction (5 mins)
    Start by asking students what the biggest number they know how to count to is. Briefly review counting to 20. Tell them that today they will learn to count even higher, all the way to 120!
  • Watch the Boddle Learning Video (5 mins)
    Play the Boddle Learning video 'Counting Up to 120 - First Grade Math (1.NBT.1.S4-S6)'. Encourage students to count along with the video.
  • Counting Trees and Flowers (5 mins)
    Review the first part of the video where they counted trees and flowers. Ask students how many trees they counted (5) and how many flowers they counted (8). Have them count out 5 small objects (e.g., blocks, crayons) and then 8 small objects.
  • Counting Pens and Stars (10 mins)
    Review the part of the video where they counted pens and stars. Emphasize how grouping by tens makes counting easier. Ask students: 'How many groups of ten pens were there?' (2) 'How many extra pens were there?' (3) 'So, how many pens were there in total?' (23). Repeat with the stars: 'How many groups of ten stars were there?' (7) 'How many extra stars were there?' (5) 'So, how many stars were there in total?' (75).
  • Counting Paperclips (5 mins)
    Review the paperclip example. Ask: 'How many groups of ten paperclips were there?' (10) 'What number is ten tens?' (100) 'How many extra paperclips were there?' (4) 'So, how many paperclips were there in total?' (104).
  • Practice Activity (10 mins)
    Give each student a worksheet with different groups of objects (e.g., circles, squares, triangles) arranged in rows of ten. Have them count the objects by circling groups of ten and then counting the remaining ones. Write the total number on the line.
  • Wrap Up (5 mins)
    Review the main concepts of the lesson: counting to 120 and grouping by tens. Ask students to share one thing they learned during the lesson.

Interactive Exercises

  • Counting Jar
    Fill a jar with a variety of small objects (e.g., buttons, beads). Have students work in pairs to count the objects by grouping them into tens.
  • Number Line Hop
    Create a number line from 1 to 120 on the floor. Have students hop along the number line, counting aloud.

Discussion Questions

  • Why is it helpful to group objects into tens when counting?
  • Can you think of other times when we use groups of ten in our daily lives?
  • What is the biggest number you can count to now?
