Key Concepts

  • Doubles facts (adding a number to itself)
  • Number recognition
  • Addition within 10

Learning Objectives

  • Students will be able to recall doubles facts from 0+0 to 5+5.
  • Students will be able to represent doubles facts using fingers and objects.
  • Students will be able to match doubles facts with their correct sums.

Educator Instructions

  • Introduction (2 mins)
    Begin by greeting the students and introducing the learning goal: learning doubles facts up to 10. Briefly explain what 'doubles facts' means (adding a number to itself).
  • Flashcard Review (5 mins)
    Show flashcards with doubles facts (0+0, 1+1, 2+2, 3+3, 4+4, 5+5). Read each fact aloud and have the students repeat it. Emphasize the sum of each doubles fact.
  • Finger Practice (5 mins)
    Guide students to use their fingers to represent each doubles fact. For example, for 2+2, have them show 2 fingers on each hand. Then, count all the fingers together to find the sum (4).
  • Object Representation (5 mins)
    Use small objects (pebbles, counters, blocks) to represent doubles facts. For example, for 3+3, place 3 objects in one group and 3 objects in another group. Have students count all the objects together to find the sum (6).
  • Matching Game (8 mins)
    Prepare cards with doubles facts (e.g., 2+2) and separate cards with the corresponding sums (e.g., 4). Have students match the doubles facts with their correct sums. This can be done individually or in small groups.
  • Review and Wrap-up (5 mins)
    Review all the doubles facts learned during the lesson. Ask students to share their favorite doubles fact and explain why. Encourage them to practice their doubles facts at home.

Interactive Exercises

  • Doubles Fact Hopscotch
    Create a hopscotch grid with numbers representing the sums of doubles facts (0, 2, 4, 6, 8, 10). Call out a doubles fact (e.g., 2+2) and have students hop to the correct sum (4).
  • Doubles Fact Drawing
    Have students draw pictures to represent doubles facts. For example, for 4+4, they could draw 4 apples on one side of the paper and 4 apples on the other side, then count them all.

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.
