  1. Kitty’s Even or Odd Christmas Tree • By Ms. Campbell

  2. Please help Kitty decorate our Christmas Tree!

  3. Can you help Kitty decide if the number of ornaments for the Christmas tree are even or odd?

  4. There are two kinds of numbers. There are odd numbers and even numbers. All numbers are either odd or even. Even Odd

  5. Kitty wants to know what makes a number even or odd? Even numbers can be split into equal whole parts. Odd numbers cannot.

  6. Two ornaments are a pair of ornaments. It takes two equal parts to make a pair. Split the pair apart, and you have two equal parts and none left over. Two is even.

  7. A number that can be split into equal parts with none left over is even. A number that has one left over after you split is odd. • Three ornaments can be split into a pair with one ornament left over. • Three is odd.

  8. Four ornaments can be split equally with none left over. Four is even.

  9. Five ornaments can be split but an ornament is left over. • Five is odd + With One left over

  10. Six ornaments can be split into two groups of three with none left over. + Six is even

  11. Zero is different • It does not follow the rule for odd and even numbers. • If you have zero ornaments, you • cannot split them.

  12. In a number line, every other number is odd or even. Zero is found next to the number one. One is odd, so zero is called an even number. • --|-------|------|-------|-----|------|--- 0 1 2 3 4 5 6 EVEN ODD EVEN ODD EVEN ODD EVEN

  13. KITTY SAYS… • THE DIGIT THAT A NUMBER ENDS IN TELLS YOU IF THAT NUMBER IS ODD OR EVEN. • FIVE IS ODD. FIFTEEN AND ANY NUMBER THAT ENDS IN FIVE IS ODD. EIGHT IS EVEN. TWENTY-EIGHT AND ANY NUMBER THAT ENDS IN EIGHT IS EVEN. • ZERO IS EVEN. ONE HUNDRED AND ANY NUMBER THAT ENDS IN ZERO IS EVEN!

  14. THE END

  15. TEKS Addressed: • (K.2) Number, operation, and quantitative reasoning. The student describes order of events or objects. • B) name the ordinal positions in a sequence such as first, second, third, etc. • (1.5) Patterns, relationships, and algebraic thinking. The student recognizes patterns in numbers and operations. • (B) find patterns in numbers, including odd and even; • (K.3) Number, operation, and quantitative reasoning. The student recognizes that there are quantities less than a whole. • The student is expected to: • (A) share a whole by separating it into two equal parts; and • (B) explain why a given part is half of the whole. • (2.8) Geometry and spatial reasoning. The student recognizes that a line can be used to represent a set of numbers and its properties. • The student is expected to use whole numbers to locate and name points on a number line.
