Key Concepts

  • Subtraction as taking away
  • Identifying the initial amount, the amount taken away, and the remaining amount
  • Using visuals and objects to understand subtraction

Learning Objectives

  • Students will be able to define subtraction as 'taking away'.
  • Students will be able to solve simple subtraction problems using objects and visuals.
  • Students will be able to identify the parts of a subtraction problem (initial amount, amount taken away, remaining amount).

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about taking things away. Use simple examples like sharing toys. Introduce the word 'subtraction' and explain that it means taking away or making a number smaller.
  • Video Viewing (7 mins)
    Watch the 'Learn Grade 1 - Maths - Concept and Preparation of Subtraction' video. Pause at intervals to ask questions and check for understanding.
  • Guided Practice (10 mins)
    Work through similar examples to those in the video on the whiteboard or using manipulatives (e.g., counters, blocks). For example: 'If we have 7 crayons and we take away 3, how many are left?' Guide students to count and solve the problem.
  • Independent Practice (10 mins)
    Provide students with subtraction worksheets or simple word problems to solve on their own. Circulate to provide support and answer questions.
  • Wrap-up (3 mins)
    Review the key concept of subtraction. Ask students to share examples of when they use subtraction in their daily lives.

Interactive Exercises

  • Cupcake Subtraction
    Provide students with a set of play cupcakes. Give them subtraction problems to solve by physically taking away cupcakes. (e.g., Start with 5 cupcakes, take away 2. How many are left?).
  • Drawing Subtraction
    Give students problems to solve using drawing. (e.g., Draw 6 circles, cross out 2. How many circles are left?).

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 = _.
