Grade 4 math worksheet focusing on number sequences, including counting in ones, tens, hundreds, and thousands.

Let’s solve each part step by step. We’re counting forward or backward in ones, tens, hundreds, or thousands — just like climbing up or down stairs, one step at a time.

1. Count on or back in ones

(a) 5702, 5703, 5704 → next numbers are +1 each time
→ 5705, 5706, 5707

(b) 2745, 2744, 2743 → going backward by 1
→ 2742, 2741, 2740

(c) 3105, 3104 → then blank, blank, 3101, blank
We go: 3105, 3104, 3103, 3102, 3101, 3100

2. Count on or back in tens

(a) 1631, 1621, 1611 → subtracting 10 each time
→ 1601, 1591, 1581

(b) 9005, 9015 → adding 10 each time
→ 9025, 9035, 9045, then 9055 (which matches the last given number)

(c) 7928, 7938 → adding 10
→ 7948, 7958, then 7968 (given), then 7978

Wait — let’s check:
7928 → +10 = 7938 → +10 = 7948 → +10 = 7958 → +10 = 7968 → +10 = 7978
Yes, so blanks are: 7948, 7958, 7978

But the sequence is: 7928, 7938, ___, ___, 7968, ___
So positions:
1st: 7928
2nd: 7938
3rd: ? → 7948
4th: ? → 7958
5th: 7968 (given)
6th: ? → 7978

Correct.

3. Count on or back in hundreds

(a) ___, 2662, 2562, ___, ___, 2262
Look: from 2662 to 2562 → minus 100
So before 2662 should be 2762
Then after 2562: 2462, 2362, then 2262 (matches)

So: 2762, 2662, 2562, 2462, 2362, 2262

Blanks: first blank = 2762, then after 2562: 2462 and 2362

(b) 6610, 6510 → minus 100 each time
→ 6410, 6310, 6210, then 6110 (given)

Sequence: 6610, 6510, ___, ___, ___, 6110
So: 6410, 6310, 6210

(c) 8040, 8140 → plus 100
→ 8240, 8340, then 8440 (given), then 8540

Sequence: 8040, 8140, ___, ___, 8440, ___
So: 8240, 8340, 8540

---

4. Count on or back in thousands

(a) 2744, 3744, 4744 → adding 1000 each time
→ 5744, 6744, 7744

(b) 7099, 6099 → minus 1000
→ 5099, 4099, 3099, then 2099 (given)

Sequence: 7099, 6099, ___, ___, ___, 2099
So: 5099, 4099, 3099

(c) 9251, 8251 → minus 1000
→ 7251, 6251, 5251, then 4251 (given)

Sequence: 9251, 8251, ___, ___, ___, 4251
So: 7251, 6251, 5251
