Key Concepts

  • Place Value (Tens and Ones)
  • Counting by Tens
  • Representing Numbers with Models

Learning Objectives

  • Students will be able to identify the tens and ones digits in a two-digit number.
  • Students will be able to represent two-digit numbers using models of tens and ones.
  • Students will be able to count by tens and ones to determine the value of a number.

Educator Instructions

  • Introduction (5 mins)
    Start by welcoming the students and briefly introducing the concept of place value. Ask them if they know what tens and ones are and give a simple example (e.g., 10 fingers make one group of ten).
  • Video Time! (7 mins)
    Play the Kids Academy video: 'Practice Place Value for 1st Grade'. Tell students to watch carefully how the video uses pearls on a string to represent tens and single pearls to represent ones.
  • Let's Count Together! (8 mins)
    After the video, review the concepts presented. Use a whiteboard or projector to draw your own models of tens and ones. Guide students through counting the tens and then adding the ones. Demonstrate both the 'counting on' method and the T-chart method.
  • Practice Worksheet (10 mins)
    Distribute a worksheet with similar problems to those in the video. Have students work individually or in pairs to count the tens and ones and write the corresponding number. Circulate to provide assistance as needed.
  • Wrap Up (5 mins)
    Review the answers to the worksheet as a class. Ask students to explain how they found their answers. Reiterate the importance of understanding place value for future math skills.

Interactive Exercises

  • Building Numbers with Manipulatives
    Provide students with base-ten blocks (or similar manipulatives like straws and rubber bands). Ask them to build different numbers using the blocks, focusing on representing the correct number of tens and ones. For example, ask them to build the number 34.
  • Place Value Bingo
    Create bingo cards with numbers in the range covered in the lesson. Call out descriptions like "Two tens and three ones." Students mark the corresponding number on their bingo cards.

Discussion Questions

  • What is the difference between a ten and a one?
  • Can you give me an example of a number that has 2 tens and 5 ones? What number is that?
  • Which way of counting (counting on or T-chart) did you find easier? Why?

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.A.1:Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral. CCSS.Math.Content.1.OA.C.5:Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
