Key Concepts

  • Addition
  • Making 10
  • Unknown Addend

Learning Objectives

  • Students will be able to determine the missing number needed to add to a given number to reach 10.
  • Students will be able to visualize addition problems using a 10-frame model.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they know about the number 10. Ask them to share different ways they can make 10 (e.g., 5+5, 2+8). Explain that today they'll be learning a new way to make 10 using boxes and circles.
  • Video Viewing (5 mins)
    Play the Khan Academy video 'Getting to 10 by filling boxes'. Encourage students to pay attention to how the circles are added to the boxes to make 10.
  • Guided Practice (10 mins)
    After the video, draw a 10-frame (a rectangle divided into 10 equal squares) on the board. Present problems similar to the video (e.g., 4 + ___ = 10). Have students draw circles in the boxes to represent the first number, then count how many more circles are needed to fill all 10 boxes. Write the complete equation on the board.
  • Independent Practice (10 mins)
    Provide students with worksheets containing 10-frames and addition problems with a missing addend (e.g., 2 + ___ = 10, 7 + ___ = 10). Have them draw circles in the boxes to solve the problems independently.
  • Wrap Up (5 mins)
    Review the answers to the independent practice problems. Ask students to share what they learned about making 10. Emphasize that filling the boxes helps them see how many more they need to get to 10.

Interactive Exercises

  • Ten-Frame Game
    Use online ten-frame tools (search 'interactive ten frame') or create a physical ten-frame using manipulatives. Call out a number and have students fill in the ten-frame with that many counters. Then, have them figure out how many more counters they need to make 10.

Discussion Questions

  • What is your favorite way to make 10?
  • How does filling the boxes help you solve the addition problems?

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 = _.
