Description

This activity is a way for students to understand measuring in standard ways (using an inch ruler only) and non-standard ways (using unifix cubes). Students measure 10 different objects found in the classroom, including their own hands and feet, then record their findings.

Objectives

The student uses standard customary and metric (centimeter, inch) and nonstandard units, such as links or blocks, in measuring real quantities.

Materials

- 1 Teacher basket used by the teacher for modeling the activity which consists of the following: stapler, dictionary, pair of scissors, CD case
- 1 Teacher Measurement worksheet
- 2 Sheets of white construction paper
- 1 Pencil
- 1 Inch Ruler
- Measurement worksheet (see associated file) for each student
- 1 Basket of student supplies for each group consisting of the following:
--1 Unsharpened pencil
--1 Eraser
--1 Marker
--1 Pre-measured string
--1 Straw
--1 Popsicle stick
--1 Glue stick
--1 Blackboard eraser
--1 Baggie with unifix cubes

Preparations

1. Duplicate the Measurement worksheet to be used when during the activity for students and the teacher.
2. Set up a separate teacher modeling basket filled with supplies that include the following materials: stapler, dictionary, scissors and CD case.
3. Fill each student group basket with supplies. These are listed in the Materials section of this plan.
4. Gather and count out construction paper and pencils needed for each student.
5. Duplicate enough Measurement worksheets for each student.

Procedures

1. Ask students why they think we measure things. What do we measure with?

2. Explain to the students we are going to measure 10 things. First, in a standard way, then in a non-standard way, using different measurement tools.

3. Explain that using a standard measuring tool will result in precise, more accurate measurements.

4. Model how to measure correctly with a ruler, as well as cubes, by measuring four specific items that were put in a separate teacher basket, which include a stapler, a dictionary, scissors, and a CD case.

7. Encourage someone from each table to volunteer and come up to the front of the class to measure one of the four teacher chosen items, using both measuring tools.

8. Write down responses on the board or a chart previously prepared. This should be a replica of their record sheet, but with the four different objects to model the format the students need to follow on their sheets.

9. Explain that the record sheet will be used as a final written product as a way to check for their understanding.

10. Display the supplies that are in the baskets and tell the students that each group will get a basket and that they will measure and record each object.

11. Explain that they will also trace their own hands and feet (shoes), either left or right, and then measure and record those findings as well.

12. Explain that they will need to share the supplies in the basket, but that each group will get their own basket. Therefore, each student measures all objects and traces and measures their hands and feet at different times, but they will all be completed by the time the lesson is finished. Stress the importance of using time wisely.

13. Walk around frequently and check for students' understanding.

14. Collect the record sheets after all of the measurements are complete and review the findings together.


Assessments

Use the completed Measurement worksheet to formatively assess the studentís ability to
--Use rulers to measure objects in inches.
--Use unifix cubes to measure objects in non-standard form.

The two performance levels are as follows.
--Mastered: Student is able to correctly use standard form of measurement as well as non-standard form of measurement by measuring at least 70% of the items correctly.
--Not yet Mastered: Student does not complete at least 70% of the student Measurement worksheet correctly. (These students will be assisted by other team members to provide greater opportunity to master the skill of measurement.)
