6.NS.C.6 lessons
Understand a rational number as a point on the number line: opposite signs show locations on opposite sides of 0, the opposite of the opposite of a number is the number itself, and integers can be found and positioned on horizontal or vertical number lines. (The coordinate-plane parts are not taught.)
The Common Core State Standards for Mathematics code 6.NS.C.6 asks students to: “Understand a rational number as a point on the number line: opposite signs show locations on opposite sides of 0, the opposite of the opposite of a number is the number itself, and integers can be found and positioned on horizontal or vertical number lines. (The coordinate-plane parts are not taught.)” These Fieldbook lessons teach it hands-on, with everyday materials, a printable teacher guide and a student sheet.

- How cold can ice get? 50–60 min
Teams measure the temperature of ice water, then stir salt into crushed ice and watch the thermometer fall well past zero. Students read negative temperatures on a vertical number line, order integers, and explain opposites and how far each temperature is from zero.
- Which is further from sea level? 50–60 min
The class builds a 2 m tall number line on the wall, from the bottom of the deepest ocean trench to the top of Mount Everest, and places real places on it at a scale of 1 cm for every 100 m. Students explain elevation above and below sea level with integers, compare with absolute value, and find that the Challenger Deep is further from sea level than Everest is high.
