1. Solve problem 1 - Grade 4 Kite Workbook Page 8
Problem:
Challenge: 'Riddle Me This!'
- Name the shapes you've mastered.
- Explain how to calculate the perimeter of a triangle, quadrilateral, rectangle, and square.
- Detail the process for finding the area of a rectangle and a square.
- List the units of measurement for length, weight, volume, and area that you've learned.
Solving Method:
Recall the knowledge you've acquired, students.
Answer:
- Recall the shapes we've studied: triangle, quadrilateral, rectangle, square
- Explain how to calculate the perimeter of a triangle, quadrilateral, rectangle, square.
+ To find the perimeter of triangles and quadrilaterals, add up the lengths of all sides.
+ To calculate the perimeter of a rectangle, add the length and width (in the same unit) then multiply by 2.
+ To find the perimeter of a square, multiply the length of one side by 4.
- Explain how to calculate the area of a rectangle, square.
+ To calculate the area of a rectangle, multiply the length by the width (using the same unit).
+ To calculate the area of a square, multiply the length of one side by itself.
- List the units of measurement for length, weight, volume, and area that have been covered in class.
+ Units of length measurement: mm, cm, dm, m, dam, hm, km, ...
+ Units of weight measurement: tonne, ton, carat, kg, hg, dag, g, ...
+ Units of volume measurement: liter, cm3, mm3, dm3, m3, ...
+ Units of area measurement: mm2, cm2, dm2, m2, ...
2. Exercise 2 - Kite Grade 4 Workbook 1 page 8
Exercise:
a) Use a protractor to check and then name the right angles, non-right angles in the following shapes:
b) Measure the lengths of the following sides then calculate the perimeter, area of each shape:
Solving Method:
a) Use a protractor to check right angles, non-right angles
b) Apply the formula:
Perimeter of rectangle = (length + width) x 2
Perimeter of square = Length of side x 4
Answer:
a) The right angles in the above shape are:
+ Right angle at vertex N, sides NO, NM
+ Right angle at vertex I, sides IH, IK
+ Right angle at vertex B, sides BA, BC
b) AB = CD = 6cm; AD = BC = 3 cm
Perimeter of rectangle ABCD is:
(6 + 3) x 2 = 18 (cm)
Area of rectangle ABCD is:
6 x 3 = 18 (cm2)
All sides are equal: GH = HI = IK = KG = 3 cm
Perimeter of square GHIK is:
3 x 4 = 12 (cm)
Area of square GHIK is:
3 x 3 = 9 (cm2)

Problem:
Paint each face of each solid with a different color. How many colors are needed to paint all the faces of each solid?
Solving Method:
- Each solid has 6 faces
- Number of colors needed = Number of faces of each solid x number of solids
Answer:
We observe that each solid has 6 faces.
The number of colors needed to paint all the faces of each solid is:
6 x 2 = 12 (colors)
Answer: 12 colors

6. Solve Problem 6 - Grade 4 Kite Workbook Page 9
Problem:
A wastewater treatment system in a production facility treats 36,000 liters of wastewater per day stored in 4 equal tanks. Each tank contains the following liters of wastewater:
A. 4,000 liters
B. 6,000 liters
C. 9,000 liters
D. 12,000 liters
Solution Method:
Number of liters of wastewater in each tank = Number of liters of wastewater treated per day : number of tanks
Answer:
Each tank contains the following liters of wastewater:
36,000 : 4 = 9,000 (liters)
Answer: 9,000 liters
Choose C

Problem:
Examine the layout of booths at a Handicraft Fair and identify the booth with the largest area.
Solution Method:
Count the number of squares in each booth.
Booth with more squares will have a larger area.
Answer:
Pottery booth occupies area: 16 squares
Lacquer booth occupies area: 8 squares
Sculpture booth occupies area: 6 + 6 = 12 squares
Bamboo booth occupies area: 2 + 2 = 4 squares
Wooden furniture booth occupies area: 12 squares
Therefore, the pottery booth has the largest area.
