Pellwater Reservoir's Dry Summer: Reading the Gauge as Decimals
A grade 4 lesson where students rewrite a fictional reservoir's gauge readings as tenths and hundredths, then compare two drops written as decimals.
Common Core Math · Grade 4
4.NF.C.6 Use decimal notation for fractions
Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
Why water teaches this standard well
Students record a rain gauge reading like three-tenths of an inch as the decimal 0.3 on a storm-tracking chart, then locate that value on a number line between whole inches. Writing rainfall as a decimal is exactly how a real weather report displays the day's precipitation.
