I'll solve this problem by analyzing the image, which shows a worksheet titled "Base Ten Blocks and Number Expanders." The task is to look at the base ten blocks in each row and write the matching number in the expander (tens and ones columns).
Let me go through each row on the left side of the worksheet:
First row:
- I can see 1 long block (representing 10) and 3 small cubes (representing 1 each)
- This equals 10 + 3 = 13
- So, tens = 1, ones = 3
Second row:
- I can see 2 long blocks (representing 20) and 4 small cubes (representing 4)
- This equals 20 + 4 = 24
- So, tens = 2, ones = 4
Third row:
- I can see 3 long blocks (representing 30) and 1 small cube (representing 1)
- This equals 30 + 1 = 31
- So, tens = 3, ones = 1
Fourth row:
- I can see 4 long blocks (representing 40) and 2 small cubes (representing 2)
- This equals 40 + 2 = 42
- So, tens = 4, ones = 2
The right side of the worksheet appears to be identical, so the answers would be the same for those rows.
The solution to this problem is to count the base ten blocks in each row and decompose the total number into tens and ones. Base ten blocks are a visual tool used in mathematics education to help students understand place value. The long blocks represent tens (each is worth 10), and the small cubes represent ones (each is worth 1). By counting these blocks, students can practice decomposing numbers into their place value components.
