Purpose and Instructional Strategies

• Instruction includes students describing measurable attributes and using vocabulary such as tall, short, long, heavy and light (MTR.4.1). 
• Instruction includes the introduction of terms to compare measurable attributes, such as longer, shorter, heavier and lighter. 
• Instruction includes concrete objects as well as images and context to describe measurable attributes (MTR.7.1). 
• The expectation of this benchmark is not to focus on numerical values of measurement by estimating or measuring, but to develop understanding of attributes that can be measured and vocabulary used to describe those attributes.

Common Misconceptions or Errors

• Students may confuse measurable attributes and call an object big when they mean it is heavy, long, or tall. Explain that tall is a measure of height from bottom to top and long is a measure of length from one end to the other.
• Students may assume that there is only one way to describe attributes.
  • Students may not understand that an object can be both short and heavy.
  • Students may think that because an item has a large volume it means that the item is also heavy.

Strategies to Support Tiered Instruction

• Instruction includes opportunities to use the same object to explore multiple attributes during different lessons, as they actively participate in experiences that include inquiries in which length, volume, and weight must be considered. Students are encouraged to verbalize their thinking while a teacher scaffolds instruction by teaching measurement vocabulary and providing sentence frames during the activity.

• Teacher guides student discussions and models a think-aloud about each attribute by connecting student-centered language with key mathematical vocabulary. The results of measurement investigations are recorded with drawings, labeling, and verbal communication to peers or teacher about their results.
  
  • For example, how many ways can we measure a bucket?

Instructional Tasks

Instructional Task 1 (MTR.1.1, MTR.7.1)

Provide students with various objects (or cards with pictures of objects) of different sizes (lengths, heights, and weights). In small groups ask students to sort the objects by different attributes; such as shortest to longest or lightest to heaviest. Facilitate conversations with the group focusing on developing student’s vocabulary and development of corresponding concepts. Compare different ways of sorting the objects (for example, the longest may not be the heaviest, etc.).

 

Instructional Items

Instructional Item 1 

Connect each object to (a) word(s) that could be used to describe it.
