# GM1-1: Order and compare objects or events by length, area, volume and capacity, weight (mass), turn (angle), temperature, and time by direct comparison and/or counting whole numbers of units.

This means students will go through a stage of using direct comparison to establish the relative length, area, volume, weight and temperature of objects. This means that the objects are brought together physically. Through experiences using direct comparison techniques students will come to appreciate the need for units of measure so that objects can be compared without bringing them together. Units have the attribute being measured, have to be the same size and are combined and counted. For example handspans can be used to compare the length of a table and the height of a door. Students are expected to apply their number strategies to count these units. Students are expected to explore turns (angles) through bodily movement and time through comparing durations of events.

- Students will be able to explain the idea of doubling in measurement (measure it and then add/count on the same number of units to get the new measurement)
- Students will be able to measure an object in non-standard units and find “twice” or “double” by counting.
