Key Concepts

  • Subtraction as taking away
  • Using the minus sign (-)
  • Solving subtraction problems with numbers up to 10
  • Understanding zero in subtraction

Learning Objectives

  • Students will be able to define subtraction as taking away from a group.
  • Students will be able to solve simple subtraction problems with numbers up to 10.
  • Students will be able to identify and use the minus sign (-) in a subtraction equation.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about taking things away. Introduce the concept of subtraction as taking away. Show them the minus sign (-) and explain that it means we are subtracting.
  • Video Viewing (7 mins)
    Play the Homeschool Pop video 'Subtraction Practice'. Encourage students to pay attention to the bakery examples and how subtraction is used to find out how many items are left.
  • Bakery Subtraction Practice (10 mins)
    Present subtraction problems based on the bakery theme. For example: 'If the bakery has 7 cookies and sells 3, how many are left?' Use drawings or manipulatives (like counters) to help students visualize the subtraction process. Encourage students to write out the equations (e.g., 7 - 3 = 4).
  • Real-Life Subtraction (8 mins)
    Ask students to think of real-life situations where they might need to subtract. For example: 'You have 5 toys, and you give 1 to your friend. How many do you have left?' Have students share their scenarios and solve them together.

Interactive Exercises

  • Cookie Subtraction
    Give each student 10 small cookies (or counters). Call out subtraction problems (e.g., 'Eat 2 cookies!'). Have them physically take away the cookies and then count how many are left. Write the equation on the board.
  • Drawing Subtraction
    Provide students with a worksheet containing simple subtraction problems. Have them draw pictures to represent each problem and then cross out the number being subtracted to find the answer.

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).
