Students learn about sorting and classifying objects by size while reading Eric Carle's "The Grouchy Ladybug". In this sorting and classifying lesson, students first listen to and interact with the story. They then look at cut-outs of...

First graders follow directions when sorting objects. They illustrate how objects are categorized by drawing at least two of the categories that they sorted the objects into. Students work in small groups at completing the task of...

In this ordering by length worksheet, students with a partner study and analyze different ways to understand the concept of length better through comparing objects and pictures.

Students discover how to classify and categorize items by sorting various objects. As they sort the items, they explain how the items are alike. By repeating the sorting procedure several times, students determine there are numerous...

Specific learning goals are grouped for different grade levels spanning pre-kindergarten to eighth grade. After preparing the questions and materials, you call a learner to come in front of the class and play the game. Young learners...
