Stepping up to medium difficulty, Rules & Matching asks second graders to think about why numbers are even or odd. Part A contains nine fill-in-the-blank prompts about equal groups, ones digits, and the smallest two-digit examples. Part B is a matching activity that pairs the numbers 36, 59, 84, and 17 with descriptions like Even, ends in 4 or Odd, ends in 9, deepening pattern recognition through justification.
Style:
Even and Odd Numbers
Part A: Fill in the Blank

1. A number is even if it can be divided into two equal groups.
2. The ones digit of every even number is 0, 2, 4, 6, or 8.
3. The number 53 is odd because it ends in 3.
4. The number 78 is even because it ends in 8.
5. If you have 14 apples, you can make two equal groups of 7.
6. The ones digit of every odd number is 1, 3, 5, 7, or 9.
7. The number 100 is even.
8. An odd number plus one always equals an even number.
9. The number 41 is odd because it ends in 1.
