Key Concepts

  • Subtraction
  • Taking Away
  • Numbers up to 10
  • One-to-one correspondence

Learning Objectives

  • Students will be able to subtract numbers from 10 using manipulatives.
  • Students will be able to determine the remaining quantity after subtracting from 10.
  • Students will be able to understand the concept of 'taking away' in subtraction.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they know how many items are in a dozen. Explain that a dozen is 12, but you'll be working with 10 today. Show the egg carton and count the 10 compartments together by twos: 2, 4, 6, 8, 10. Explain that you will use the egg carton and eggs to help with subtraction.
  • Subtraction Demonstration (10 mins)
    Place 10 eggs in the egg carton, one in each compartment. Model a subtraction problem (e.g., 10 - 4). Physically remove 4 eggs and ask students how many eggs are left. Count the remaining eggs together. Repeat this process with different numbers (10 - 1, 10 - 5, 10 - 3, 10-10), emphasizing the 'taking away' action each time.
  • Guided Practice (10 mins)
    Have students work along with you, placing 10 objects (e.g., small toys, blocks, crayons) in a row. Call out subtraction problems (e.g., 10 - 2) and have them physically remove the corresponding number of objects. Ask them to count how many objects are left and state the answer. Circulate to assist students as needed.
  • Independent Practice (10 mins)
    Provide students with individual worksheets or number bonds with subtraction problems subtracting from 10. Have them solve the problems independently, using objects or drawings as needed. Ensure students understand that the first number is the number they start with, and the second number is how many they are taking away.
  • Wrap-up (5 mins)
    Review the concept of subtraction as 'taking away'. Ask students to share one thing they learned during the lesson. Emphasize that using objects can help them understand subtraction better. Ask the students what number sentences they learned in the video, such as 10-4=6, 10-1=9, 10-5=5, 10-3=7, and 10-10=0.

Interactive Exercises

  • Object Subtraction
    Provide students with a set of 10 manipulatives (e.g., counters, blocks). Call out a subtraction problem (e.g., 10 - 3). Students physically remove the specified number of objects and state the answer (how many are left).
  • Drawing Subtraction
    Have students draw 10 objects on a piece of paper. Call out a subtraction problem (e.g., 10 - 5). Students cross out the specified number of objects in their drawing and count how many 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.B.4:Understand subtraction as an unknown-addend problem. For example, subtract 10 - 8 by finding the number that makes 10 when added to 8.
