Working with a partner, they can then estimate how many hands would cover different objects in the room and try it to find out the correct answer. Have students record the information using a grid. Repeat the activity using other, non-standard units. Read a story that develops the concept of sequencing events in time. Discuss the pattern with the children.
Students can then create their own stories based on personal experiences.
At first, young children find out about the size of particular objects by making direct comparisons. For example, they place objects on top of each other to see which is bigger or longer. Gradually, with ample first-hand experience, they learn to estimate and compare what is being measured with a suitable standard unit of measure. As they work and talk about objects and events that are important to them, they offer insights into their thinking. Observe Observe students during whole-class or partner activities when they are ordering objects according to size.
