This worksheet involves understanding place value using base-10 blocks. The blocks represent different values:
-
Large blue squares represent
100s (hundreds).
-
Yellow rods represent
10s (tens).
-
Small orange cubes represent
1s (ones).
We need to count the number of each type of block in each set and calculate the total value.
Solution:
#### 1)
-
1 large blue square: \(1 \times 100 = 100\)
-
3 yellow rods: \(3 \times 10 = 30\)
-
Total: \(100 + 30 = 130\)
Answer: 130 blocks
#### 2)
-
2 large blue squares: \(2 \times 100 = 200\)
-
5 small orange cubes: \(5 \times 1 = 5\)
-
Total: \(200 + 5 = 205\)
Answer: 205 blocks
#### 3)
-
1 large blue square: \(1 \times 100 = 100\)
-
4 yellow rods: \(4 \times 10 = 40\)
-
6 small orange cubes: \(6 \times 1 = 6\)
-
Total: \(100 + 40 + 6 = 146\)
Answer: 146 blocks
#### 4)
-
2 large blue squares: \(2 \times 100 = 200\)
-
1 yellow rod: \(1 \times 10 = 10\)
-
2 small orange cubes: \(2 \times 1 = 2\)
-
Total: \(200 + 10 + 2 = 212\)
Answer: 212 blocks
#### 5)
-
5 small orange cubes: \(5 \times 1 = 5\)
-
Total: \(5\)
Answer: 5 blocks
#### 6)
-
3 large blue squares: \(3 \times 100 = 300\)
-
8 yellow rods: \(8 \times 10 = 80\)
-
Total: \(300 + 80 = 380\)
Answer: 380 blocks
#### 7)
-
3 large blue squares: \(3 \times 100 = 300\)
-
4 yellow rods: \(4 \times 10 = 40\)
-
5 small orange cubes: \(5 \times 1 = 5\)
-
Total: \(300 + 40 + 5 = 345\)
Answer: 345 blocks
#### 8)
-
3 large blue squares: \(3 \times 100 = 300\)
-
4 yellow rods: \(4 \times 10 = 40\)
-
3 small orange cubes: \(3 \times 1 = 3\)
-
Total: \(300 + 40 + 3 = 343\)
Answer: 343 blocks
