Key Concepts

  • Addition
  • Making 10
  • Unknown Addend

Learning Objectives

  • Students will be able to determine the number needed to add to a given number to reach 10.
  • Students will be able to represent addition problems using objects (like bananas) and equations.

Educator Instructions

  • Introduction (5 mins)
    Start by asking students if they like bananas. Then, pose a scenario: 'Imagine you have some bananas, but you want a bunch of 10. How many more do you need?' Briefly discuss different ways to find the answer.
  • Video Viewing (5 mins)
    Play the Khan Academy video 'Adding to 10' (https://www.youtube.com/watch?v=9FC0WT186aY). Instruct students to pay attention to how the video uses bananas to show addition to 10.
  • Guided Practice (10 mins)
    After the video, work through a similar problem together on the board. For example: 'Let's say we have 4 apples. How many more apples do we need to have 10 apples?' Draw 4 apples and then draw additional apples while counting aloud until you reach 10. Write the equation: 4 + 6 = 10.
  • Independent Practice (10 mins)
    Give each student a worksheet with addition problems where they need to find the missing number to reach 10. Use simple problems like: 2 + ? = 10, 5 + ? = 10, 1 + ? = 10. They can draw pictures to help them solve the problems.
  • Wrap-up (5 mins)
    Review the answers to the worksheet problems. Ask students to share different strategies they used to find the missing numbers. Emphasize that there are multiple ways to solve addition problems.

Interactive Exercises

  • Banana Counting Game
    Provide students with small, manipulatives (like banana-shaped candies or counters). Call out a number (e.g., '3'). Students must count out that many manipulatives and then figure out how many more they need to reach 10. They then show you the additional manipulatives they needed and say the complete equation (e.g., '3 plus 7 equals 10').

Discussion Questions

  • What does it mean to 'add' something?
  • Can you think of other times you need to add things together in your daily life?

Educational Standards

CCSS.Math.Content.1.OA.A.1:Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. 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). CCSS.Math.Content.1.OA.D.8:Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ - 3, 6 + 6 = _.
