This 3-page 5th grade science and math sheet uses rounded lengths for an average adult: esophagus 1 foot, stomach 1 foot, small intestine 20 feet and large intestine 5 feet. Part 1 asks for the difference between the two intestines, the total length of all four parts and the small intestine in yards, to the nearest yard. Part 2 gives a blank bar graph scaled 0 to 22 feet in steps of 2 and one written question about coiling. Page 3 shows the worked answers.

“Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.”
Part 1, question 3 converts 20 feet to yards and rounds 6 2/3 to 7.
“Read a data table and show the numbers on a bar graph.”
Part 2 asks students to draw four bars to scale, including two that stop halfway between 0 and 2.
A four-row table of organ lengths and three questions with answer boxes. Students subtract 5 from 20, add all four lengths and divide 20 feet by 3 to find yards, with a hint that 3 feet equal 1 yard.
An empty bar graph with the organs along the bottom and feet up the side. Students draw four bars, then write why a small intestine of 20 feet fits inside the body.
The three calculations (15 feet, 27 feet, 7 yards), the height of each bar and a model sentence about the coiled small intestine.
Tape it out
Mark 20 feet on the hallway floor with tape before the lesson. Students see how long the small intestine is before they work out how it fits.
Check the scale
The esophagus and stomach bars both stop halfway between 0 and 2, so ask students to say what each gridline is worth before they draw.
Rounding check
Question 3 gives 6 2/3 yards. Use it as a quick check on who rounds to 6 and who rounds to 7.
