This Grade 3 hard worksheet explores half-unit line plots with challenging questions about range, mode, and total measurements. Students work with ribbon and crayon data measured to the nearest half inch, finding the difference between the largest and smallest values, identifying the tallest stack as the mode, and computing the total number of items measured. Multiple-choice and fill-in items push Grade 3 learners to reason carefully about half-inch scales and line plot frequency.
