Skip Counting By Tens - Worksheets - Free Printable

Let's solve the problem step by step.

Problem:

The image shows a worksheet titled "Count by 10s". It has three vertical columns of boxes connected by curved arrows. The task is to fill in the missing numbers in the boxes, counting by 10s, following the arrows.

We are given some starting numbers and need to fill in the rest based on counting forward or backward by 10s.

Step-by-step Analysis:

#### Column 1 (Leftmost):
- Starts at 125
- Arrows go downward, so we count down by 10s.
- Sequence:
125 → 115 → 105 → 95 → 85 → 75

So the boxes from top to bottom should be:
- 125
- 115
- 105
- 95
- 85
- 75

✔ All filled correctly.

#### Column 2 (Middle):
- Starts at 65
- Arrows go downward, so again count down by 10s
- Sequence:
65 → 55 → 45 → 35 → 25 → 15

So the boxes from top to bottom:
- 65
- 55
- 45
- 35
- 25
- 15

✔ All filled correctly.

#### Column 3 (Rightmost):
- Starts with 10 at the bottom
- Arrows go upward, so we count up by 10s
- But we see that the first box (top) has a circle with 100 inside it — this is likely a clue or starting point.

Wait — let’s look closely.

At the top of the third column, there’s a box with a circle and 100 inside. Then below it, the arrow goes down to a blank box, then continues down.

But the bottom of the column says 10, and the arrow points upward.

So let’s trace the path:

From bottom to top:
- Bottom box: 10
- Arrow up to next box: 20
- Then: 30, 40, 50, 60, 70, 80, 90, 100

But wait — the top box already has 100 in a circle. So we must fill the boxes going from 10 up to 100, increasing by 10s.

So the sequence from bottom to top:
- 10 → 20 → 30 → 40 → 50 → 60 → 70 → 80 → 90 → 100

Now, how many boxes are there?

Looking at the image:
- There are 10 boxes in the rightmost column.
- The top one has 100 (already filled).
- The bottom one has 10 (already filled).

So we need to fill the middle 8 boxes.

List them from top to bottom:
1. 100 ✔ (given)
2. 90
3. 80
4. 70
5. 60
6. 50
7. 40
8. 30
9. 20
10. 10 ✔ (given)

So the blanks in the middle column (right) are:
- 90, 80, 70, 60, 50, 40, 30, 20

But wait — looking back at the image, the arrows go from bottom to top, so we fill from bottom up.

But since the boxes are stacked vertically, we write from top to bottom:

Top to bottom:
- 100 (given)
- 90
- 80
- 70
- 60
- 50
- 40
- 30
- 20
- 10 (given)

So the empty boxes in the right column are:
- 90, 80, 70, 60, 50, 40, 30, 20

Final Answer:

Let’s summarize all the filled values:

#### Left Column (Start: 125, down by 10s):
- 125
- 115
- 105
- 95
- 85
- 75

#### Middle Column (Start: 65, down by 10s):
- 65
- 55
- 45
- 35
- 25
- 15

#### Right Column (Start: 10, up to 100 by 10s):
- 100 (given)
- 90
- 80
- 70
- 60
- 50
- 40
- 30
- 20
- 10 (given)

Explanation:

- The task is to count by 10s.
- In each column, follow the direction of the arrows.
- For left and middle columns: subtract 10 as you go down.
- For right column: add 10 as you go up (so subtract 10 when filling from top to bottom).
- The pattern is consistent: every number differs by 10 from the next.

✔ All numbers are multiples of 10, and sequences are correct.

Final Filled Numbers:

| Column | Top to Bottom |
|--------|---------------|
| Left | 125, 115, 105, 95, 85, 75 |
| Middle | 65, 55, 45, 35, 25, 15 |
| Right | 100, 90, 80, 70, 60, 50, 40, 30, 20, 10 |

This completes the "Count by 10s" exercise.
