Lesson 2 - Classification keys
Lesson overview
Students focus on constructing and using simple classification keys. After watching the Creating your own classification key video, they choose a collection of everyday items (such as a pencil case or kitchen utensils) and create a branching key that sorts the items based on obvious features first, then more specific features. Students can build and share their keys digitally using tools like Jamboard to collaborate and refine their groupings.
Learning intention
We are practising using features to group things.
Success criteria
We can create and use a simple classification key.
Activity 1 - How can you create a classification key?
Tasks
- View the Creating your own classification key video.
- Create a classification key for a group of everyday items.
- Start with the most obvious features of the item.
- Move to more specific features as you progress.
- Remember, each line in the branch must have two choices.
- Use Google slides or another app to create your classification key. Use this tool to collaborate with others and build a key together.
Equipment needed
- A collection of everyday items such as the contents of a pencil case, cooking equipment or pantry items.

Practise making your own classification key using everyday items. Here I'm going to classify items from a pencil case.
The first thing I need to do is to divide the items into two obvious groups. Some of the items I can draw with, others I cannot. From here I'm going to continue this process of dividing them into two groups until all of my items are classified.
