    Piggybacking off of Heidi’s example is this one for volume. This comes from

    Direct Comparison: Which bottle holds more?

    Indirect Comparison: Pour liquid into one bottle then pour contents of that bottle into the opposite one to see whether it overflows and in that case the first bottle holds more; or if there is still room in the bottle than that bottle holds more.Indirect Measure: Use a smaller cup and fill it and count the number of cups that each container holds. Container a holds 4 cups while container b hold 3.5 cups.

    Direct Measure: Volume of a liter is equal to a 10 x 10 x 10 cm cube.
