Key Concepts

  • Adding zero to a number
  • Identity property of addition (adding zero doesn't change the number)
  • Understanding 'nothing' in the context of addition

Learning Objectives

  • Students will be able to add zero to any number within 20.
  • Students will be able to explain that adding zero to a number doesn't change its value.
  • Students will be able to solve simple addition problems involving zero.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what happens when they have some toys and then get zero more. Lead them to understand that the number of toys stays the same. Introduce the concept of adding zero in math.
  • Video Viewing (7 mins)
    Watch the "Grade 1: Math Lesson # 41 Addition Facts - Adding Zero" video. Encourage students to pay attention to how Mrs. Lawson uses gems to demonstrate adding zero.
  • Guided Practice (8 mins)
    Work through examples together as a class. Use manipulatives like counters or drawings to represent adding zero to numbers between 1 and 10. Ask questions like: 'If I have 3 apples and add 0 apples, how many apples do I have?'
  • Independent Practice (10 mins)
    Give students worksheets with simple addition problems involving zero (e.g., 5 + 0 = __, 0 + 2 = __). Have them complete the problems individually.
  • Wrap-up (5 mins)
    Review the main concept: adding zero to a number always gives you that same number. Ask students to share what they learned. Do a quick oral quiz to check understanding.

Interactive Exercises

  • Number Line Hop
    Use a number line. Start at a number (e.g., 4). Tell students to add zero. Ask them where they land on the number line. Repeat with different starting numbers.
  • Hands-On Addition
    Provide each student with a small bag of objects (e.g., small toys, beads). Call out an addition problem (e.g., 'Hold up 6 toys. Now add zero toys. How many do you have?').

Discussion Questions

  • What happens when you add zero to your age?
  • Can you think of a time when you added zero of something in real life?
  • Does it matter if we write 0 + 5 or 5 + 0? Why?

Educational Standards

CCSS.Math.Content.1.OA.B.3:Apply properties of operations as strategies to add and subtract. (Students need not use formal terms for these properties.) Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.) CCSS.Math.Content.1.OA.C.6:Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
