Order, Order!

This activity helps students develop a sense of the relative size of quantities in time, length and mass. Learners rank their estimates of given measures in order from least to greatest and justify their decisions. The Teachers' Notes page includes suggestions for implementation, discussion questions, ideas for extension and support, printable cards (pdf), and a link to a related problem, "In Order" (cataloged separately). The solutions page shows that students used standard units of measure to make their comparisons.

      seed of a good idea

    • Once again NRICH gives us a starting point that has endless possibilities. Vary the measure attributes and the four items. This is a great thinking and writing prompt for students.
