Instruction in the standards requires a focus not only on the learner concepts and competencies but the supportive practices employed by the adults in the classroom setting. 

Concepts and Competencies

The learner will:

• Classify up to 20 objects using one attribute into categories
• display the number of objects in each category
• count and compare the quantities of each category
• describe the difference
• Construct arguments using concrete objects to classify items (e.g. ask “Why is this true?” and “Does this make sense?”)
• Connect the different representations and explain the connections

Supportive Practices

The adult will:

• Introduce and use measurement and comparative vocabulary
• Practice one to one matching to reinforce number conservation concept (e.g. size versus number of objects)
• Pose questions about number conservation
• Provide opportunities to develop a logical argument to describe the differences and relationships with classified objects
• Provide opportunities to use concrete objects to sort and classify independently and in small groups
