This Grade 3 easy line plot worksheet introduces students to whole-number data sets like the number of siblings, books read, and plant heights in centimeters. Learners count X marks above each value, identify the mode by finding the tallest stack, and determine the total number of items represented. Sentence correction tasks reinforce key vocabulary such as X mark, mode, and number line, while true or false items check basic understanding of how Grade 3 line plots work.
