Key Concepts

  • Subtraction
  • Using a table to subtract
  • Finding the difference

Learning Objectives

  • Students will be able to use a table to solve subtraction problems.
  • Students will be able to identify the correct answer to a subtraction problem using a table.
  • Students will be able to explain how to use the table to find the difference between two numbers.

Educator Instructions

  • Introduction (5 mins)
    Start by asking students what they already know about subtraction. Review what subtraction means (taking away) using simple examples like 'If you have 5 apples and eat 2, how many are left?' Connect it to the video by mentioning Starry and her marbles. Briefly introduce the concept of using a table as a tool to help with subtraction.
  • Watch the Video (7 mins)
    Play the 'Learn Grade 1 - Maths - Using Tables for Subtraction' video. Tell students to pay close attention to how Starry uses the table to solve subtraction problems.
  • Guided Practice (10 mins)
    After watching the video, draw a similar table on the board. Work through a few subtraction problems together as a class, guiding students to use the table. For example, 'Let's solve 6 - 3. Where do we start on the table? Which way do we move?' Emphasize the steps: Find the first number, move down, find the second number across, and see where they meet.
  • Independent Practice (10 mins)
    Give students worksheets with subtraction problems and tables. Have them work independently or in pairs to solve the problems using the table. Circulate to provide assistance and answer questions.
  • Wrap Up (3 mins)
    Review the key concept: using a table for subtraction. Ask students to share one thing they learned. Reiterate that the table is a helpful tool, and they can use it to check their answers even if they know another way to subtract.

Interactive Exercises

  • Marble Subtraction Game
    Similar to the video, use marbles (or other small objects) to create subtraction problems. Then, use the table to check the answers. For example: 'I have 7 marbles and give away 4. Let's use the table to see how many are left!'
  • Table Scavenger Hunt
    Write subtraction problems on index cards. Hide the cards around the room. Students find a card, use the table to solve the problem, and write the answer on the card.

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.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. 1.OA.D:Work with addition and subtraction equations.
