Foods might also be classified by likes and dislikes. Follow-up with writing, drawing, graphing, and making charts allows for extension beyond science. Students must orally describe objects, listen, and take turns as they relate the attributes of objects and ways of classifying. This is also an opportunity to discover symmetry as students examine pairs. Recording and discussing will require many of the Common Essential Learnings.
Students can collect objects from home to use in classifying.
Tubes, boxes of different sizes and colours, marbles, balls, etc. can be left at a centre for students to classify. Large laminated charts with headings could be provided for student use. This provides for vocabulary extension. An alternative would be to have students use magazines to cut out pictures of objects. These can then be labelled and made into large charts.
