Lesson Plan of Length/Mass/Capacity

 

Lesson Planning of Measurement of Length, Mass and Capacity (Addition of Units of Length)

Subject Mathematics

Grade 3rd

Students` Learning Outcomes

  • Add measures of length in same units with and without carrying.
  • Solve real life problems involving same units of length for addition with and without carrying.

Information for Teachers

  • Same units of measurement can be added, as;
  • Centimetre can be added into centimetre
  • Meter can be added into meter
  • Kilometre can be added into kilometre.
  • While teaching the lesson, the teacher should also consult text book at all steps wherein and whenever it is applicable.

Material / Resources

Writing board, chalk/marker, duster, stick, ruler, meter rode and measuring tape etc.

Introduction

  • Describe a situation
  • There are four baskets two of apples and two for oranges
  • Ask from students how many oranges and how many apples.
  • Point out that we can sum apples with apples and oranges with oranges only.
  • Teacher can use copies and book alternatively.

Development

Teaching Approach

Inquiry, problem solving

 

Activity 1 (Problem solving)

  • Ask student to make pairs and each pair to measure the length of their pencils and note down in their note books.
  • Ask them what is the total length of their pencils?

10 cm + 15 cm =

    Centimetre

  1  0 cm

+1  5 cm

2  5 cm

 

 

Activity 2

Ask the students to add the following quantitative

40 cm  +  10 cm

15 cm  +  4 cm

35 cm  +  12 cm

5 m  +     62 m

123 km  +  76 km

100 km  +  85 km

Guide the students in writing unit digit under unit digit and tens digit under tens digit and hundreds digit under hundred digit.

        Centimetre,      Centimetre   

           4   0 cm             1  5 cm

         +1  0 cm            +   4

            5  0 cm            1  9 cm 

        Meter,            Meter   

       3  5 m              0  5 m

    + 1 2 m          +  6  2 m

       4 7 m              6  7 m

  Kilometre,          Kilometre

    1 2 3 km            1 0 0 km    

 +   7  6 km         +   8  5 km  

   1 9 9 km             1 8 5 km 

Ask the students to solve the following sums:

100 m  +  100 m  =

57 m  +  15 m  =

16 km  +  69 km =

39 cm  +  51 cm  =

589 km  +  306 km  =

900 km  +  100 km  =

155 km  +  715 km  =

365 km  +  26 km  =

 

 

Activity 3 (Problem solving)

  • Ahmad`s school is shown in the following picture. Ahmad goes to school from his home and returns to home. What is the total distance he covers?
  • Distance from Ahmad`s home to school = 150 m  +  60 m  +  100 m = 310 m
  • Distance from Ahmad`s school to home = 150 m  +  60 m  +  100 m = 310 m
  • Total distance = 310 m  +  310 m = 620 m
  •  

Nadia during her walk covers 425 km distance 1st day. Next day she covers 350 km distance. What is total distance she covers in two days?

  • Ask from students:
  • Distance covered on 1st day         = 425 km
  • Distance covered on 2nd day       =  350 km
  • Total distance covered                =   775 km

 

 

 

Sum up / Conclusion
  • Inform to students that we have learned today how to add two or more lengths together.
  • Ask from students:
  • Can we add m into cm and km into m?
  • Bring them to the point that they know that same units cm be added together.

Assessment

  • A boy has two pieces of string one with 47 m long and other 21m long. Find the total length of the string.
  • Teacher is also required to involve the students in solving the problems given in the exercise at the end of unit / chapter.

Follow up

  • Measure the heights of your family members and find the total height of them. Measure the lengths of all your books and find the total lengths of your entire book.
