A complete 14-day unit for Grade 7 The Number System, grounded in the Mountain Hiking Trip scenario. Every lesson connects to the same authentic context, so students see how 7.NS skills work together instead of as disconnected topics.

Every lesson connects to the class planning and tracking a mountain hiking trip - elevation changes (positive/negative integers), temperature shifts, supply weights (fractions and decimals), pace tracking, and cost splits. Students see how 7.NS skills come together to plan a real adventure. The 12th lesson and summative performance task bring it all together.
