Classifying is the grouping or sequencing of objects or events according to a recognized scheme, based on observations and/or estimating and measuring. Grouping objects is a way of imposing order based on similarities, differences, and interrelationships.
Teacher background, procedures, student recording pages, rubrics for scoring, poster for classifying, vocabulary cards, and writing pages are included in this packet.
Next Generation Science Standards:
Analyzing and Interpreting Data Analyzing data in K 2 builds on prior experiences and progresses to collecting, recording, and sharing observations.
• Use observations (firsthand or from media) to describe patterns in the natural world in order to answer scientific questions.
In this sequence of lessons, students observe, describe, and classify rocks in the first activity. A poster is provided to help students develop important thought processes involved in classifying. Then students are provided with writing prompts and asked to describe how they sorted their rocks into two groups. For the second activity, students bring in small objects or “treasures” from their homes or outdoors, which are put into class collections or “treasure boxes.” Groups of students observe, describe, and classify a “treasure box.” The treasures are classified using a binary classification system, a Venn diagram, and finally a graph. In the final writing activity, students make journal entries of a sequence of events from the perspective of an explorer looking for treasure.
Writing and Math Common Core State Standards included.
With guidance and support from adults, recall information from experiences or gather information from provided sources to answer a question.
Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
Write narratives in which they recount two or more appropriately sequenced events, include some details regarding what happened, use temporal words to signal event order, and provide some sense of closure.
