This is a very fun, hands-on activity to teach students how to classify. This file includes student directions, classification templates, and a candy key for students to use as a reference during the activity. Students are given different types of candy and they have to work together to classify the candy into as many different groups as possible. All of their thinking is recorded on the classification templates. Students then can share out their groupings they came up with, which leads to a great classroom discussion on what classification is and why it is important. Students also have to reflect and record how they classify objects in their everyday lives and how classification is and can be applied to science units they have been studying. I use this activity as a precursor to astronomy in order to get students to think about how they could classify the planets, but you could use this in the same way to classify insects, plants, etc. Also, if you can't find all of the candy listed on the key students can use the pictures instead of the actual candy. There are 15 different candies listed, but this activity could easily be scaled down for lower grades by including less types of candy and giving more specific detail such as classify by size, color, and shape rather than leaving it open-ended.
