þ
hand out materials to students, will have an arrow symbol (
) by them.
Purpose of Lesson 3:
• In this lesson, the tutor and the students will
ü select the best unit to measure weight/mass and capacity;
ü read weight/mass and capacity measurements;
ü estimate weight/mass and capacity measurement; and
ü convert from one unit of measurement to another.
Equipment/Materials Needed:
• Paper and pencils
• Copies of Student Sheets 24 – 26, and the Mathematics Reference Sheet
(Student Sheet 27)
• An object that weighs about one pound, an object that weighs about one
ounce, an object that weighs about one kilogram, and an object that
weighs about one gram
Preparations before beginning Lesson 3:
• Run off one copy of Student Sheets 24 – 26 for each student and the
