1. Solve problem 1 - Grade 4 Kite Book Volume 1, page 84
Problem:
Mental Calculation:
Solution Method:
Apply the rule of multiplication by 10, 100, 1,000
Answer:
5 x 10 = 50
5 x 100 = 500
5 x 1,000 = 5,000
32 x 10 = 320
32 x 100 = 3,200
32 x 1,000 = 32,000
183 x 10 = 1,830
183 x 100 = 18,300
183 x 1,000 = 183,000
307 x 10 = 3,070
560 x 100 = 56,000
105 x 1,000 = 105,000
2. Solve problem 2 - Kite Grade 4 Workbook Page 84
Problem:
Apply the properties of multiplication to mentally calculate (following the example):
Solution Method:
Utilize the properties of multiplication
3 x 50 = 150
3 x 200 = 600
2 x 4 000 = 8 000
3 x 50 = 150
4 x 300 = 1,200
3 x 7,000 = 21,000
9 x 70 = 630
5 x 300 = 1,500
6 x 2,000 = 12,000
3. Solve problem 3 - Grade 4 Kite Book Volume 1 page 85
Problem:
Apply the properties of multiplication to mentally calculate:
Method of solution:
Apply the multiplication property
Answer:
20 x 70 = 20 x 7 x 10 = 140 x 10 = 1,400
40 x 40 = 1,600
300 x 40 = 12,000
600 x 30 = 18,000
2,000 x 30 = 60,000
43 x 1,000 = 43,000
4. Solve problem 4 - Grade 4 Kite Book Volume 1 Page 85
Problem:
A store stacks notebooks into boxes, with each box containing 1,000 notebooks. How many notebooks are there in 43 such boxes?
Number of notebooks 43 boxes can contain = Number of notebooks per box x 43
Answer:
43 boxes like that can contain the total number of notebooks:
43 such boxes can contain:
43,000 (notebooks)
