Practical Exercise

1. Solve Exercise 1 Page 43 Math Grade 3

Problem: Here is a statistical chart of the number of products each class has created from used plastic bottles.

a) How many products of each type did each class make?
b) Which class made the most pen holders?
c) What is the total number of plant pots made by all three classes?

Solution Guide:
a) Use the statistical chart to answer the questions.
b) Compare the number of pen holders made by each class to find the class that made the most pen holders.
c) The total number of plant pots for all three classes = number of plant pots in class 3A + number of plant pots in class 3B + number of plant pots in class 3C.

Answers:
a) Observing the chart, we see:
Class 3A made 5 plant pots and 7 pen holders.
Class 3B made 8 plant pots and 6 pen holders.
Class 3C made 7 plant pots and 8 pen holders.
b) Class 3C made the most pen holders.
c) The total number of plant pots made by all three classes is: 5 + 8 + 7 = 15 (plant pots).

Problem: During the year-end party, 36 students from class 3D attended. They planned: each person would have 1 banana, 2 cakes, and 5 lychees. Calculate the amount of food class 3D needs for the party.

Solution Guide:
The number of bananas class 3D needs = number of attendees x 1.
The number of cakes class 3D needs = number of attendees x 2.
The number of lychees class 3D needs = number of attendees x 5.

Problem: Below is a statistical chart of the number of trees planted in the school garden by 3rd-grade classes.

a) Which class planted the most trees? Which class planted the fewest trees?
b) How many trees did both classes 3A and 3C plant together?
c) How many more trees did class 3C plant compared to class 3B?

Solution Guide:
a) Compare the number of trees each class planted and draw conclusions.
b) The number of trees both classes 3A and 3C planted = Number of trees class 3A planted + Number of trees class 3C planted.
c) The number of trees class 3C planted more than class 3B = Number of trees class 3C planted - Number of trees class 3B planted.

Answers:
a) Observing the statistical chart, we see: Class 3C planted the most trees, and class 3B planted the fewest trees.
b) Both classes 3A and 3C planted a total of 85 trees.
c) Class 3C planted 20 more trees than class 3B.

2. Solve Exercise 2 Page 44 Math Grade 3

Problem: Below are the heights of the four highest mountains in Vietnam:

3,096 m; 3,046 m; 3,143 m; 3,076 m.
a) In the table below, the names of the mountains are written in order from highest to lowest. Replace the .?. with the given measurements to create a table of the heights of the four highest mountains in Vietnam.

b) How much higher is Phan Xi Păng mountain compared to Pu Si Lung mountain?
c) How many meters is Ky Quan San mountain shorter than Pu Ta Leng mountain?

Solution Guide:
a) Complete the statistical table based on the given information.
b) To calculate how much higher Phan Xi Păng mountain is than Pu Si Lung mountain, subtract the height of Pu Si Lung mountain from the height of Phan Xi Păng mountain.
c) To calculate how many meters Ky Quan San mountain is shorter than Pu Ta Leng mountain, subtract the height of Ky Quan San mountain from the height of Pu Ta Leng mountain.

Answers:
a)

b) Phan Xi Păng mountain is higher than Pu Si Lung mountain by:
3,143 - 3,076 = 67 (m)
c) Ky Quan San mountain is shorter than Pu Ta Leng mountain by:
3,096 - 3,046 = 50 (m)
