During Unit 2, your child will begin to develop an understanding of the meaning and processes of measurement.  Students will spend the majority of their time in this cluster describing and comparing measurable attributes. Your child will also classify objects in a variety of ways.  Classification involves making decisions about how to categorize things.  Young children need experiences with categorizing things in different ways in order to learn to make sense of real-world data.

Key Vocabulary

Your child needs to:

  • Describe measurable attributes of objects, such as length or weight.  Describe several measurable attributes of a single object. (Use measurement and geometric vocabulary (e.g. sides) when describing the attributes of objects)

 

  • Directly compare two objects with a measurable attribute in common, to see which object has “more of”/”less of” the attribute, and describe the difference.  (For example; directly compare the heights of two children and describe one child as taller/shorter.)

 

  • Classify objects into given categories; count the number of objects in each category and sort the categories by count.  (limit category counts to be less than or equal to 10) 

 

  • Continue to support adding and subtracting  fluently to 20 with +1, -1, +0, and -0.
