Mental Math Worksheet with six questions on multiplication, division, and number patterns for elementary students.

Let’s solve each problem one by one, step by step.

Problem 1: 34 × 4 = ?

We can break it down:
- 30 × 4 = 120
- 4 × 4 = 16
- Add them: 120 + 16 = 136

Looking at the options:
(1) 1216 → too big
(2) 181 → not right
(3) 136 → matches!
(4) 128 → close but wrong

✔ Correct answer is (3)

Problem 2: “16, 20, 24, 28, ...” — counting in what?

Look at the difference between numbers:
- 20 - 16 = 4
- 24 - 20 = 4
- 28 - 24 = 4

So we’re adding 4 each time → counting in fours

Options:
(1) eights → no
(2) twos → no
(3) tens → no
(4) fours → yes!

✔ Correct answer is (4)

Problem 3: 6 + 6 + 6 + 6 + 6 = □ × 6

How many 6s are being added? Let’s count:
First 6, second 6, third 6, fourth 6, fifth 6 → that’s five 6s.

So: 5 × 6 = 30 → which means the missing number is 5

Options:
(1) 5 → correct
(2) 6 → no
(3) 30 → that’s the total, not the multiplier
(4) 36 → too big

✔ Correct answer is (1)

Problem 4: 56 sweets shared equally among 8 children — how to find how many each gets?

When you share things equally, you divide.

So: 56 ÷ 8

Check options:
(1) 56 + 8 → adds more sweets → wrong
(2) 56 × 8 → multiplies → way too many
(3) 56 – 8 → subtracts → doesn’t share equally
(4) 56 ÷ 8 → YES! That’s division for sharing

✔ Correct answer is (4)

Problem 5: 24 ÷ 4 is the same as ___

First, calculate 24 ÷ 4 = 6

Now check which option equals 6:

(1) 2 × 3 = 6 → ✔
(2) 2 × 4 = 8 → no
(3) 2 × 6 = 12 → no
(4) 3 × 6 = 18 → no

✔ Correct answer is (1)

Problem 6: 1 book has 34 pages. How many pages in 9 books?

Multiply: 34 × 9

Break it down:
- 30 × 9 = 270
- 4 × 9 = 36
- Add: 270 + 36 = 306

Options:
(1) 333 → no
(2) 306 → yes!
(3) 276 → too low
(4) 43 → way too small

✔ Correct answer is (2)
