Whole Class Math:
Choices:
 * measuring the garden (1/3 of the class with Heidi) [[file:Garden Mapping Project.doc]]
 * pencil comparisons [[file:pencil comparisons.doc]]
 * measuring the classroom [[file:measuring the classroom.doc]]
 * How many Cubes Long [[file:How many cubes long.doc]]

Things to look for:
 * Do students start at the beginning of the object?
 * Are they careful to line up their measurement unit without overlapping or having spaces between them?
 * What do they do when the measurement is not exact? Do they understand halves or parts? Use the phrases "a little more than 4" and "a little less than 4." If they use the word half, encourage them and talk about what it means.
 * Do students understand that if their unit is bigger, they need fewer of them to measure their object?
 * If they are measuring something very long, do they think of putting cubes or other objects in groups to make counting easier?
