  1. In this lesson you will solve addition problemsby using complements of ten and their multiples.

  2. What did the zero say to the eight? Nice belt!

  3. No, no not that kind of compliment. complements Ron & Hermione Oreo Cookie & Oreo Cream Park Place & Boardwalk

  4. 1 + 9 2 + 8 3 + 7 40 + 60 = 100 4 + 6 5 + 5

  5. A common mistake is to mix up the place value of complements. 4 + 6 14 + 6 14 + 60

  6. 3 + 7 = 10 300 + 700 = 1000 3H + 7 H = 10H 1000 – 800 = 200 10 H – 8 H = 2 H

  7. 6 T + 4 T = 10 T 2,360 + 1,440 3,000 + 700 + 100 = 3,800

  8. 623 + 293 = ?  6 H + 2 T + 3 O 2 H + 8 T + 13 O 9 T + 3 O 916 800 + 100 + 16 =

  9. In this lesson you have learned how to solve addition problemsby using complements of ten and their multiples.

  10. What number goes in the blank? 1,158 + 4,31 = 6,089 1 1 , 1 5 8 + 4 ,3 1 9 6 , 0 8 9

  11. Play a game with the class in which students face forward and you say one half of a complement such as “6” the students then turn backwards and say the other half, “4”. You can make this more challenging by saying “700” and students say “300” or “650” and “350”.

  12. For students who need more help adding complements keep base ten blocks on hand, and have students rewrite equations with larger numbers in terms of one’s and “hundreds” written out in words or as a letter, so they can see the complements more readily.

  13. Add 1,732 + 2,365 using what you know about complements. Decompose 3,467 to add it to 5,722 using complements.
