Skill 25B Estimate and Measure Here we want to see if your student can estimate the length of an object in inches. Your computer screen resolution can affect the pencil image size so you will need to use your own judgment to determine if the student needs to practice this skill. For the second question, your student needs to pick up a ruler and place it against the screen to measure its length.

Do not use a ruler. Estimate how many inches long you think it is.

Next, use a ruler and measure the exact length of the pencil rounded to the nearest inch.
