1. Solve Exercise 1 on Page 10 of Math 3 Textbook
Problem: Look at the following shapes and identify objects in the shape of a cube, rectangular prism, cylinder, sphere:
Solution: Observe the objects, identify their characteristics to recognize the shapes.
Answer:
The objects in the shape of a cube are: Gift box, Rubik's cube.
The objects in the shape of a rectangular prism are: Book, Silk paper box, Cookie box.
2. Solve Exercise 2 on Page 10 of Math 3 Textbook
Problem: a) Measure then read the name of the longest line segment among the following line segments:
b) Draw the length of line segment MN which has a length of 1 decimeter.
Solution:
a) Use a ruler to measure the lengths of the line segments. Then, compare the lengths of the line segments to find the longest one.
b) Convert: 1dm = 10cm. Use a straightedge to draw line segment MN with a length of 10cm.
Answer:
Using a ruler to measure the lengths of the line segments, we obtain the following results:
AB = 11cm; AC = 7cm; EG = 9cm; PQ = 10cm.
Therefore, the longest line segment is line segment AB.
Convert: 1dm = 10 cm. Draw a line segment MN with a length of 10 cm:

Problem: Turn the minute hand on the clock to indicate:
a) 7 o'clock, 1:30, 12:15.
b) 2:30 PM, 10 PM, 4:15 PM.
Solution: Rotate the minute hand clockwise from right to left to get the required hours as stated in the problem.
Answer:
a) We rotate the clock hands to the following positions:
b) 14:30 is 2:30 PM.
22:00 is 10:00 PM.
16:15 is 4:15 PM.
We rotate the clock hands to the following positions:

4. Solve Exercise 4 on Page 11 of Math 3 Textbook
Problem: Fill in the appropriate numbers in the blanks?.
Solution:
+ Count the number of water bottles/milk cartons/paint cans in each figure.
+ Observe how many liters of water each water bottle/milk carton/paint can contains.
+ Use multiplication to find the result.
Answer:
Figure 1: There are 6 water bottles, each containing 1 liter of water.
The number to be filled in is 6.
Figure 2: There are 10 milk cartons, each containing 2 liters of milk. So we have: 2l x 10 = 20 l.
The number to be filled in is 29.
Figure 3: There are 5 paint cans, each containing 5 liters of paint. So we have: 5l x 5 = 25l.
The number to be filled in is 25.
5. Solve Exercise 5 on Page 11 of Math 3 Textbook
Problem: Observe the diagram below and answer the questions:
a) The distance from Nguyen's house to Khuê's house is longer than the distance from Nguyen's house to the library by how many meters?
b) How many meters is the shortest distance from Ngan's house to the amusement park?
Solution:
a) Observe the drawing, find the lengths of the distances:
+ Distance from Nguyen's house to Khue's house.
+ Distance from Nguyen's house to the library.
+ Distance from Nguyen's house to Khue's house longer than distance from Nguyen's house to the library = distance from Nguyen's house to Khue's house - distance from Nguyen's house to the library.
b) Observe the roads from Ngan's house to the amusement park.
Calculate the lengths of the roads and then compare.
Above is the entire solution for exercises on pages 10, 11 of Math 3 Textbook Volume 1, Kite Book in the Mathematics Grade 3 section. Remember to do extra exercises in the Workbook and compare the results to study Mathematics better.
