Key Concepts

  • Doubles in addition
  • Recognizing patterns in numbers
  • Memorizing doubles facts for quick recall

Learning Objectives

  • Students will be able to identify doubles (e.g., 1+1, 2+2, etc.)
  • Students will be able to add doubles within 12.
  • Students will be able to recognize the doubles pattern on dice.

Educator Instructions

  • Introduction (5 mins)
    Begin by welcoming students and introducing the concept of 'doubles' as being like twins - the same number twice. Show the video (Double Dice - Addition Practice | Math | 1st Grade - Kids Academy).
  • Doubles Explanation (7 mins)
    After watching the video, write down the doubles facts on the board (1+1=2, 2+2=4, 3+3=6, 4+4=8, 5+5=10, 6+6=12). Explain that remembering these facts will help them add faster.
  • Dice Activity (10 mins)
    Using physical dice or drawings of dice, have students practice identifying doubles. Roll two dice and ask, 'Are these doubles? What's the sum?'
  • Worksheet Practice (10 mins)
    Distribute a worksheet (or create one) with double dice addition problems similar to the video. Students circle the correct dice to complete each addition fact.
  • Wrap-up (3 mins)
    Review the doubles facts one last time. Ask students why knowing doubles is helpful for addition.

Interactive Exercises

  • Dice Roll and Add
    Students work in pairs. One student rolls a die. The other student has to quickly say the doubles fact (e.g., if they roll a 3, the other student says, '3 + 3 = 6').
  • Flashcard Doubles
    Create flashcards with doubles facts (e.g., 4+4). Show the flashcards and have students call out the answer.

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.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 = _.
