Let’s work through each number chart one by one.
---
First Number: 878
We break it down by place value:
-
Hundreds: 8 → So, 8 hundreds = 800
-
Tens: 7 → So, 7 tens = 70
-
Ones: 8 → So, 8 ones = 8
Digits row: Already filled as 8 (hundreds), 7 (tens), 8 (ones) — correct.
Base-10 Blocks:
You’d draw:
- 8 big squares (each = 100)
- 7 long rectangles (each = 10)
- 8 small squares (each = 1)
But since we’re writing text, we just note what goes in each box.
Expanded Form:
800 + 70 + 8

Second Number: 430
Break it down:
-
Hundreds: 4 → 400
-
Tens: 3 → 30
-
Ones: 0 → 0
Digits row: Fill in 4, 3, 0
Base-10 Blocks:
Draw 4 hundreds blocks, 3 tens rods, 0 ones cubes.
Expanded Form:
400 + 30 + 0 → or just 400 + 30
---
Third Number: 652
Break it down:
-
Hundreds: 6 → 600
-
Tens: 5 → 50
-
Ones: 2 → 2
Digits row: Fill in 6, 5, 2
Base-10 Blocks:
6 hundreds, 5 tens, 2 ones
Expanded Form:
600 + 50 + 2
---
Fourth Number: 129
Break it down:
-
Hundreds: 1 → 100
-
Tens: 2 → 20
-
Ones: 9 → 9
Digits row: Fill in 1, 2, 9
Base-10 Blocks:
1 hundred, 2 tens, 9 ones
Expanded Form:
100 + 20 + 9

Now, let’s fill everything into the charts properly.
