Sort, Fill & Check (Easy-3) opens with a sorting box where second graders drop 14, 9, 26, 5, 18, and 11 into Even or Odd columns. A five-prompt fill-in section follows, asking children to finish sentences like The number 20 is an ___ number and An odd number always ends in 1, 3, 5, 7, or ___, plus a sticker problem about splitting 8 into two equal groups.

Four true-or-false items close the page with claims such as The number 12 is an odd number and All numbers ending in 0 are even, building the ones-digit habit that anchors all later even-and-odd reasoning.
