Comparing and Ordering

Unit Plan

Comparing and Ordering

Objectives

Students will learn different ways of representing numbers, relationships among numbers, and number systems. Students will learn measurable attributes of objects and the units, systems, and processes of measurement. Students will:

  • connect number words and numerals to the quantities they represent, using various physical models and representations.
  • recognize the attributes of length, volume, weight, area, and time, and compare and order objects according to these attributes.
  • understand how to measure using both nonstandard and standard units.
  • select an appropriate unit and tool for the attribute being measured.

Essential Questions

How can data be organized and represented to provide insight into the relationship between quantities?
How can probability and data analysis be used to make predictions?
How does the type of data influence the choice of display?
In what ways are the mathematical attributes of objects or processes measured, calculated and/or interpreted?
What does it mean to estimate or analyze numerical quantities?
What makes a tool and/or strategy appropriate for a given task?
Why does “what” we measure influence “how” we measure?
  • What does it mean to estimate or analyze numerical quantities?
  • What makes a tool and/or strategy appropriate for a given task?
  • Why does what we measure influence how we measure?

    Performance Assessment:

    Performance Task

    Materials:

    Directions:

    Use the Performance Assessment Recording Sheet (M-K-6_Performance Assessment.docx) to record students’ answers.

    1.   Ask each student to pick a Tower card (M-K-6-2_Tower Cards.docx), and then, using blocks, build a tower that is taller than the tower on the card. Draw the tower the student built on the assessment recording sheet.

    2.   Give the student two more Tower cards and ask him/her to order the towers on the cards from shortest to tallest.

    Circle YES for Height if the student understands height by answering questions 1 and 2 correctly.

    Circle NO for Height if the student answered one or both questions incorrectly.

    3.   Have the student cut a straw that is shorter than an unsharpened pencil.

    4.   Hand the student two precut straws of different lengths. Have him/her show you which one is longer.

    Circle YES for Length if the student understands length by answering questions 3 and 4 correctly.

    Circle NO for Length if the student answers one or both questions incorrectly.

    5.   Hand the student an apple and a crayon and have him/her tell you which object is lighter.

    Circle YES for Weight if the student correctly compares the weight of the two objects.

    Circle NO for Weight if the student does not correctly compare the weights of the objects.
