Student Behavioral Objectives 1.1 Students will verbally describe components of a doubles fact with 90%-100% accuracy 1.2 Students will classify doubles facts from non doubles facts on a SMART board activity with 90%-100% accuracy. 1.3 Students will solve for missing double facts on a worksheet provided with 90%-100%

  4. Essential Question • How do patterns help us solve problems?

  5. Guided Questions • What is an addend? • What two numbers will always be the same in a doubles fact? • How is a doubles fact different from other facts? • Where do you see doubles in your everyday life?

  6. Enduring Understanding • A doubles fact is a number sentence with the same addends. • The sun of a doubles face can always be separated into two equal parts
