Key Concepts

  • Place Value (Ones and Tens)
  • Addition of One- and Two-Digit Numbers
  • Using T-charts as a Strategy
  • Representing Numbers with Pictures

Learning Objectives

  • Students will be able to identify the ones and tens place in a two-digit number.
  • Students will be able to add a one-digit number to a two-digit number.
  • Students will be able to add a multiple of ten to a two-digit number.
  • Students will be able to use a T-chart to solve addition problems.
  • Students will be able to represent numbers with pictures to aid in addition.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing the concept of place value (ones and tens). Ask students what each digit in a number like 23 represents (2 tens and 3 ones).
  • Video Viewing (7 mins)
    Watch the Kids Academy video "Add Ones or Tens - Place Value | Math for 2nd Grade." Encourage students to pay attention to how the T-chart and pictures are used to solve addition problems.
  • T-Chart Practice (10 mins)
    Guide students in creating T-charts to solve addition problems like 32 + 5 and 41 + 20. Emphasize aligning the numbers in the correct columns (ones with ones, tens with tens).
  • Picture Representation (10 mins)
    Demonstrate how to represent numbers using dots (for ones) and columns (for tens), as shown in the video. Have students practice drawing pictures to represent numbers and solve addition problems like 14 + 3 and 25 + 10.
  • Worksheet Activity (10 mins)
    Provide students with a worksheet containing similar addition problems. Have them use either the T-chart method or the picture representation method to find the answers.
  • Wrap Up (3 mins)
    Review the key concepts of the lesson and answer any remaining questions. Praise students for their hard work!

Interactive Exercises

  • Online Place Value Game
    Play an online place value game where students identify the ones and tens digits in a number.
  • Manipulative Activity
    Use base-ten blocks (ones and tens) to physically represent addition problems. For example, to solve 23 + 4, students would combine 2 tens blocks and 3 ones blocks with 4 ones blocks.
