The task in the image involves understanding
place value and counting groups of blocks to determine the total number represented. The blocks are typically categorized into different values:
-
Green cubes: Represent thousands (1,000 each).
-
Yellow rods: Represent hundreds (100 each).
-
Orange sticks: Represent tens (10 each).
-
Blue dots: Represent ones (1 each).
Step-by-Step Solution:
####
Left Page: Counting Blocks
The left page shows various groups of blocks. You need to count each type of block and write the total number.
1.
First Row:
- Green cubes: 2
- Yellow rods: 3
- Orange sticks: 4
- Blue dots: 5
- Total: \( 2 \times 1000 + 3 \times 100 + 4 \times 10 + 5 \times 1 = 2000 + 300 + 40 + 5 = 2345 \)
2.
Second Row:
- Green cubes: 1
- Yellow rods: 0
- Orange sticks: 7
- Blue dots: 8
- Total: \( 1 \times 1000 + 0 \times 100 + 7 \times 10 + 8 \times 1 = 1000 + 0 + 70 + 8 = 1078 \)
3.
Third Row:
- Green cubes: 3
- Yellow rods: 2
- Orange sticks: 1
- Blue dots: 6
- Total: \( 3 \times 1000 + 2 \times 100 + 1 \times 10 + 6 \times 1 = 3000 + 200 + 10 + 6 = 3216 \)
4.
Fourth Row:
- Green cubes: 0
- Yellow rods: 4
- Orange sticks: 5
- Blue dots: 9
- Total: \( 0 \times 1000 + 4 \times 100 + 5 \times 10 + 9 \times 1 = 0 + 400 + 50 + 9 = 459 \)
####
Right Page: Counting Blocks
The right page also shows groups of blocks. You need to count each type of block and write the total number.
1.
First Row:
- Green cubes: 1
- Yellow rods: 2
- Orange sticks: 3
- Blue dots: 4
- Total: \( 1 \times 1000 + 2 \times 100 + 3 \times 10 + 4 \times 1 = 1000 + 200 + 30 + 4 = 1234 \)
2.
Second Row:
- Green cubes: 0
- Yellow rods: 5
- Orange sticks: 6
- Blue dots: 7
- Total: \( 0 \times 1000 + 5 \times 100 + 6 \times 10 + 7 \times 1 = 0 + 500 + 60 + 7 = 567 \)
3.
Third Row:
- Green cubes: 2
- Yellow rods: 1
- Orange sticks: 8
- Blue dots: 9
- Total: \( 2 \times 1000 + 1 \times 100 + 8 \times 10 + 9 \times 1 = 2000 + 100 + 80 + 9 = 2189 \)
4.
Fourth Row:
- Green cubes: 3
- Yellow rods: 0
- Orange sticks: 2
- Blue dots: 3
- Total: \( 3 \times 1000 + 0 \times 100 + 2 \times 10 + 3 \times 1 = 3000 + 0 + 20 + 3 = 3023 \)
Final Answers:
#### Left Page:
1.
