Measurement (Grades 3-5)
Third, fourth, and fifth graders participate in measurement centers. They visit six different centers: standard and linear measurement, clocks, weight, volume, temperature, and converting measurements. They complete a data collection...
Illustrative Mathematics
Downhill
A car traveling down a steep hill is the model for this resource. The confusion comes when the elevation, E, is given in terms of distance, d. The distance, d, is the horizontal distance from E. Therefore, the equation, E = 7500 – 250d,...
