1 Grade 4 Mathematics Measurement: Lesson 1 Read aloud to the students the material that is printed in boldface type inside the boxes. Information in regular type inside the boxes and all information outside the boxes should not be read to students. Possible student responses are included in parentheses after the questions. NOTE: The directions read to students may depend on the available materials. Read only those parts of the lesson that apply to the materials you are using. Any directions that ask you to do something, such as to turn to a page or to hand out materials to students will have an arrow symbol ( ) by them. Purpose of Lesson 1: In this lesson, the tutor and the students will select the best unit to measure length, choose the appropriate tool to measure length, read linear measurements accurately to the nearest centimeter or 1/2 inch, estimate length, and solve problems involving length. Materials/Equipment Needed: Rulers or measuring tapes or use the ruler from the Reference Sheet Copies of Student Sheets 36 and 37 A quarter, a dime, and paper clips Ruler from the Reference Sheet 38 (Optional) Preparations before Beginning Lesson 1: Gather rulers and measuring tapes, 1 quarter, 1 dime, and a few paper clips. Run off 1 copy of Student Sheets 36 and 37 for each student. Run off 1 copy of the Reference Sheet 38 for each of the students. Cut the ruler out on each sheet. (Optional) Grade 4 Mathematics 102 Lesson 1, Measurement

4 E. The circumference of the Superdome (meters) F. The length of a new piece of chalk (cm) G. The thickness of a dime (mm) Let s estimate the lengths of different objects in the room. Choose an object to measure. Which unit do you think would be the best unit to use to measure? How many units long is the object? (It would be wise if you measured some items first so you would have a feel for the lengths.) Give Student Sheet 37. Answers: 1) 5cm 2) 2cm 3) C 4) C 5) more 6) more 7) millimeters 8) kilometers 9) meters 10) centimeters Have one student summarize today s lesson. Grade 4 Mathematics 105 Lesson 1, Measurement
