1st Grade Math Question of the Day

1. The marker
2. The crayon (correct answer)
3. They are the same length
4. You cannot tell

Explanation: This question tests 1st grade ability to order and compare objects by length (CCSS.1.MD.1). Understanding comparison statements requires knowing that if A is longer than B, then B must be shorter than A. The stimulus states 'A marker is longer than a crayon,' establishing their relative lengths. Choice B is correct because if the marker is longer than the crayon, then by definition the crayon must be shorter than the marker. Choice A is a common error where students select the first object mentioned or the longer object when asked for the shorter one, showing confusion with comparative vocabulary. To help students: Practice reversing comparison statements; use hand gestures to show relationships; create sentence pairs like 'If the marker is longer, then the crayon is shorter'; use physical objects to demonstrate that these are two ways of describing the same relationship.
