Key Concepts

  • Addition
  • Counting On
  • Missing Addend
  • Numbers 15-18

Learning Objectives

  • Students will be able to identify numbers 15, 16, 17, and 18.
  • Students will be able to find the missing addend to reach a sum of 15, 16, 17, or 18 using the 'counting on' strategy.
  • Students will be able to complete addition equations with sums between 15 and 18.

Educator Instructions

  • Introduction (5 mins)
    Start by reviewing the numbers 15, 16, 17, and 18. Show examples of these numbers using objects or drawings. Introduce the 'plus' sign and remind students that it means we are adding things together. Mention that today we will be using kites to help us practice addition.
  • Video Viewing (5 mins)
    Watch the 'Learn Grade 1 - Maths - Practicing Addition Numbers 15 to 18' video. Encourage students to pay attention to how the video uses counting on to find the missing numbers in the addition problems. Pause at key moments to ask questions.
  • Guided Practice (10 mins)
    Work through a few addition problems as a class. Use the kite examples from the video or create new ones. For example: 'We have 7, and we want to get to 15. Let's count on: 8, 9, 10, 11, 12, 13, 14, 15. How many did we count? 8! So, 7 + 8 = 15.' Emphasize the strategy of counting on from the smaller number to the larger number.
  • Independent Practice (10 mins)
    Provide students with worksheets or use a whiteboard where they can solve addition problems independently. Include problems where they need to find the missing addend to reach 15, 16, 17, and 18. Examples: 8 + ___ = 16, 9 + ___ = 17, 7 + ___ = 15.
  • Wrap Up (5 mins)
    Review the main concepts of the lesson. Ask students to share what they learned about adding numbers to reach 15, 16, 17, and 18. Briefly introduce the concept that they can use this 'counting on' strategy with other numbers as well.

Interactive Exercises

  • Number Line Addition
    Use a number line to visually represent the 'counting on' strategy. Provide problems and have students draw jumps on the number line to find the missing addend.
  • Kite Matching Game
    Create kite cutouts with numbers on them. Have students match kites that add up to 15, 16, 17, or 18.

Educational Standards

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 = _. 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.
