Lesson objective: Relate the size of the unit of measure to the number of units needed in a measured length and apply this relationship to solve a task.

This lesson provides an opportunity for students to apply their knowledge and understanding of measurement to a real-life situation. Students are asked to identify the number of objects needed based on the unit of measure in a given length. Students will construct a garden based on the directions and identify the number of plants in each row. 

Key Concept students will use: 

  • There is an inverse relationship between the size of a unit of measurement and the number of those units it takes to equal a given length.

Skills students will use:

  • Measurement and Comparing Length (Grade 1, Unit 16)

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they make sense of the problem and the units involved. Students will analyze the problem and create a map of the garden to show their solution.
