Tarrowford Farm's New Well: One-Step Equations for Watering
A 50-minute grade 6 lesson in which students write and solve one-step equations for pumping minutes, gallons added, and rows watered on a berry farm.
Common Core Math · Grade 6
6.RP.A.2 Understand the concept of a unit rate
Understand the concept of a unit rate a/b associated with a ratio a:b with b not equal to 0, and use rate language in the context of a ratio relationship.
Why water teaches this standard well
Students find the unit rate of gallons per minute from a garden hose or dollars per hundred cubic feet from a water bill, naming both as 'per one' rates. Unit rate is the single most-used water-math concept in the whole middle school curriculum, from flow rates to pricing.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
