Curated OER
Great Grams
Students measure objects effectively using standard units, They examine how consistency in the units used allows for easier and more accurate communication of mass measures.
Curated OER
Weighing stations
Learners work at a variety of stations involving practical measuring tasks. Estimation skills and the ability to measure accurately using kilograms and grams are developed.

Making Benchmarks - Mass
Elementary schoolers predict the mass for different objects. Then, using objects of 1kg mass, they make a more precise prediction. Afterwards, they discuss the need for having and using standard measures of mass.

Mass: Applying and Interpreting
Students rotate through six studying stations solving problems that involve applying and interpreting aspects of mass. They solve various word problems, and measure the contents of cans and calculate the mass of two cans.
Curated OER
Seesaws
Students make direct comparisons between objects using balance and spring scales. They also are encouraged to estimate which object is heavier by holding the objects before using the balance scales. Comparing the masses of objects is the...
