Exploring Addition Patterns -- Assessment Questions

  • Use an addition fact to find the sum of 80 + 50 = 130. (You can use the addition fact that 8 + 5 = 13, then place a zero to the right.)

  • 52 + 0 = (52). What property did you use? (Zero Property)

  • What property does 4 + 2 = 2 + 4 show? (Order Property)

  • What basic fact can you use to find 600 + 300? Explain. (6 + 3 = 9; 6 hundreds + 3 hundreds = 9 hundreds.)

  • True or false: If you add hundreds, the sum will always have 2 zeros. (False. 500 + 500 = 10 hundreds or 1,000.) Ask how this fact relates to 50 + 50. (50 + 50 = 10 tens or 100.)

  • Can you use the basic fact that 2 + 3 = 5 to find 20 + 300? (No. The non-zero digits do not have the same place value.)

    Bullying Prevention Month
    October is Bullying Prevention Month, and it's a crucial topic for teachers and administrators to address. Bullying can cause both physical and emotional harm, and it can range from inflicting physical abuse to cyber-bullying (the use of cell phones, social networking sites, and other forms of technology to cause emotional distress). Learn how to recognize several forms of bullying and teasing, and discover effective techniques for dealing with and preventing bullying in your classroom.

    Happy Halloween! Kids love this holiday and all the spooky decorations, games, and stories that go along with it. (Not to mention the candy, of course!) Take advantage of their enthusiasm with classroom connections and fun activities.
