Key Concepts

  • Counting to 8
  • Addition combinations that equal 8
  • Understanding the concept of 'equal to' (=)

Learning Objectives

  • Students will be able to count objects up to the number 8.
  • Students will be able to identify different addition combinations that result in 8.
  • Students will be able to complete simple addition equations with a sum of 8.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about the number 8. Show them the video 'Learn Grade 1 - Maths - The Story of number 8'. Explain that they will be learning all about the number 8 and different ways to make it.
  • Counting Practice (10 mins)
    Have students count objects in the classroom up to 8 (e.g., pencils, crayons, books). Draw 8 large circles on the board and have students color them. Ask them to count how many circles they colored.
  • Addition Combinations (15 mins)
    Using the video as a guide, show students different addition combinations that equal 8 (e.g., 1+7, 2+6, 3+5, 4+4). Use manipulatives like counters or blocks to visually represent each combination. Ask students to create their own combinations using the manipulatives.
  • Fill-in-the-Blank Activity (10 mins)
    Distribute worksheets with fill-in-the-blank addition problems where the sum is always 8 (e.g., 5 + __ = 8, 1 + __ = 8). Have students work individually or in pairs to solve the problems.
  • Flashcard Activity (10 mins)
    Create flashcards with pictures of objects showing different addition combinations. Have students count the objects and determine if the combination equals 8. They can give a thumbs up if it equals 8 and thumbs down if it doesn't.

Interactive Exercises

  • Building with Blocks
    Provide students with building blocks and challenge them to build towers with exactly 8 blocks. Then, ask them to divide the tower into two smaller towers, showing a different addition combination of 8.
  • Drawing Pictures
    Have students draw pictures showing different combinations of objects that equal 8. For example, they could draw 3 apples and 5 oranges.

Discussion Questions

  • What are some things you see every day that come in groups of 8?
  • Can you think of a different way to make 8 using addition?

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.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.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).
