Measuring Standard Units of Length

Lesson Plan of Measuring Standard Units of Length

Subject Mathematics

Grade III

Students` Learning Outcomes

  • Measure and write standard units of length including abbreviations.

Information for Teachers

  • In grade level 3 we only concentrate to measure the small objects, but teachers can extend objective to develop the interest of students.

Measuring Standard Units of Length

  • While teaching the lesson, also consult textbook where and when applicable.

Material / Resources

Writing board, chalk/marker, duster, ruler, meter rod, measuring tape, paper strips; paper pin, toothbrush, candle, paintbrush, key, nail, match stick

Introduction

  • Show a small scale to the students.

Measuring Standard Units of Length

  • Ask them to hold their scale in hand.

Measuring Standard Units of Length

  • Observe that some lines are longer and thicker that others; on the scale.
  • These lines indicate centimeters.
  • Reading on small scale start from 0cm to 15cm.

Development

Activity 1

  • Ask the students to measure the length of their pencil.
  • Place the ruler in such a way that one of its straight edges touches both the ends of pencil (tip of lead to top).

Measuring Standard Units of Length

  • Make sure that the left lead is at zero.
  • Count the measurement up to where top of pencil is placed on scale.
  • Write down the length of pencil on your notebook; like as Length of my pencil = 10cm.

Activity 2

  • Distribute the paper strips to students (all strips have a straight line segment of different length).

Measuring Standard Units of Length

  • Ask the students to measure the length of a line segment by using ruler.
  • Ask them to write the measurement on strip and return it.
  • Check their work and appreciate them.
  • If they make a mistake, guide them properly.

Activity 3

  • Place the things; candle, paper pin, toothbrush, paintbrush, key, nail, matchstick, and ruler on the table.

Measuring Standard Units of Length

  • Ask one of the students to pick anything from table and measure the length of it by using ruler.

Measuring Standard Units of Length

  • Write the name and measurement of object on the board. like as Length of candle is = 10cm
  • Call one by one all students to perform this activity.

Activity 4

  • Make a pair of each student.
  • Fix the measuring tape on the wall by scotch tape.

Measuring Standard Units of Length

  • Call one of the pair and ask them to measure the height of each other.
  • Ask one of the students to take off his shoes and stand straight against the wall.

Measuring Standard Units of Length

  • Put a book on top of his head. Make sure it is level. Mark off where it touches the measuring tape.
  • Count the measurement and write their heights on board.
  • Perform this activity by all pairs of students.

Sum up / Conclusion

  • Sum up the concept by repeating the rules of measurement of length;

Measuring Standard Units of Length

  • Place the ruler in such a way that one of its straight edges touches both the ends of object.
  • One of the ends of object should be placed on 0cm of scale.
  • Count the measurement up to 2nd end of object is placed on scale.

Measuring Standard Units of Length

Assessment

  • Assess the students by inquiring about the lengths of different objects and units used for measuring their lengths.

Measuring Standard Units of Length

Follow up

  • Ask the students to draw and complete the following table on their notebook.

Measuring Standard Units of Length

  • Ask the students to solve the questions given in the textbook.
