Key Concepts

  • Place Value
  • Tens
  • Ones

Learning Objectives

  • Students will be able to identify the tens and ones digits in a two-digit number.
  • Students will be able to represent numbers using bundles of tens and individual ones.
  • Students will be able to convert between tens and ones (e.g., 3 tens = 30 ones).

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they have ever helped sort things into groups. Relate this to the idea of grouping apples into bundles of 10, as shown in the video. Introduce the terms 'tens' and 'ones'.
  • Video Viewing (5 mins)
    Play the Boddle Learning video 'Understanding Place Values - 1st Grade Math (1.NBT.2)'. Encourage students to pay attention to how the video explains tens and ones using apples and blocks.
  • Guided Practice (10 mins)
    After the video, work through examples together on the board. Use drawings of bundles of ten sticks and individual sticks to represent numbers. Ask students to identify the number of tens and ones in each example (e.g., 2 bundles of ten and 5 individual sticks = 25).
  • Independent Practice (10 mins)
    Provide students with worksheets that have pictures of tens and ones blocks. Have them write the corresponding number. Alternatively, provide the number and have them draw the tens and ones representation.
  • Wrap-up (5 mins)
    Review the key concepts of place value, tens, and ones. Ask students to share what they learned and how they can use this knowledge in everyday life.

Interactive Exercises

  • Tens and Ones Game
    Use manipulatives like linking cubes or base ten blocks. Call out a number and have students build it using the blocks, separating the tens and ones. Example: "Build the number 37!"
  • Place Value Chart Activity
    Provide students with a place value chart (two columns labeled 'Tens' and 'Ones'). Give them numbers to write in the chart, emphasizing the value of each digit.

Educational Standards

CCSS.Math.Content.1.NBT.B.2:Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: CCSS.Math.Content.1.NBT.B.2.A:10 can be thought of as a bundle of ten ones — called a "ten." CCSS.Math.Content.1.NBT.C.4:Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
