It Counts
Students understand and reinforce how numbers are assigned to objects, as well as think about more, less, or equal values. In this lesson, students are asked to describe, compare, and classify plants. They should be able to use numbers...
Curated OER
Sort It Out
Students study classification systems by sorting Legos and determining how the different pieces are classified. They list as many attributes as possible to use for sorting.
Curated OER
Touch and Discover
Students work together to identify and categorize objects. They have to identify the object on touch because they are blindfolded. They record their data and describe the objects once they can look at them.

Delicious Graphing
Fourth graders sort trail mix by type and use that information to create different types of graphs for comparing.
Curated OER
Numbers Up
Students use Legos to build representations of a variety of numbers. They then sort and order their representations and pair them with the written number.
Curated OER
Cloud Shadows
Young scholars classify clouds as transparent, translucent or opaque. They conduct an experiment to determine the visual opacity of several classroom objects and then conduct further observations of clouds.
