The image shows a worksheet titled
"Base Ten Blocks Worksheets", which is designed to help children practice place value by counting base ten blocks. Base ten blocks are visual tools used to represent numbers, where:
- A
large square represents
100 (a hundred block).
- A
long rectangle represents
10 (a ten block).
- A
small square represents
1 (a one block).
Task:
Count the number of each type of block in each section and write the total number in the provided box.
Solution:
####
Step 1: Understand the blocks
-
Hundreds block: Large square = 100
-
Tens block: Long rectangle = 10
-
Ones block: Small square = 1
####
Step 2: Count the blocks in each section
#####
Section 1: Top Left
-
Hundreds blocks: 0
-
Tens blocks: 7
-
Ones blocks: 3
-
Total: \( 0 \times 100 + 7 \times 10 + 3 \times 1 = 0 + 70 + 3 = 73 \)
#####
Section 2: Top Right
-
Hundreds blocks: 0
-
Tens blocks: 8
-
Ones blocks: 5
-
Total: \( 0 \times 100 + 8 \times 10 + 5 \times 1 = 0 + 80 + 5 = 85 \)
#####
Section 3: Bottom Left
-
Hundreds blocks: 1
-
Tens blocks: 6
-
Ones blocks: 4
-
Total: \( 1 \times 100 + 6 \times 10 + 4 \times 1 = 100 + 60 + 4 = 164 \)
#####
Section 4: Bottom Right
-
Hundreds blocks: 0
-
Tens blocks: 9
-
Ones blocks: 8
-
Total: \( 0 \times 100 + 9 \times 10 + 8 \times 1 = 0 + 90 + 8 = 98 \)
Final Answers:
-
Top Left:
73
-
Top Right:
85
-
Bottom Left:
164
-
Bottom Right:
98
Explanation:
Each section requires counting the number of hundreds, tens, and ones blocks separately and then calculating the total value using place value. For example, in the top-left section, there are 7 tens and 3 ones, which add up to 73.
Final Answer:
\[
\boxed{73, 85, 164, 98}
\]
