Monster Math worksheet with fun word problems for elementary students to practice addition and subtraction.

Let’s solve each problem one by one. We’ll read carefully, decide if we need to add or subtract, and then do the math.

Problem 1:
Gary Ghoulsome ate:
- 4 cats
- 6 dogs
- 3 lizards

We want to know how many animals he ate in all → that means ADD.

So:
4 + 6 = 10
10 + 3 = 13

✔ Final answer for #1: 13

Problem 2:
Walter Werewolf scared 18 children out of their shoes.
He wants to scare 50 kids in total.
How many MORE does he need? → That means SUBTRACT (because we’re finding what’s left to reach 50).

So:
50 - 18 = ?

Let’s break it down:
50 - 10 = 40
40 - 8 = 32

✔ Final answer for #2: 32

Problem 3:
Zelda Zombie devoured:
- 3 skateboards
- 2 acrobats
- 9 trick-or-treaters

Total things she ate → ADD them all.

3 + 2 = 5
5 + 9 = 14

✔ Final answer for #3: 14

Problem 4:
They ordered pizza for $14.95
Wilby had $20.00
How much change did Wilby get? → SUBTRACT (money spent from money given)

$20.00 - $14.95 = ?

Let’s do this step by step:

Think of $20.00 as 20 dollars and 0 cents.
Subtract $14.95:

Start with cents:
0 cents - 95 cents → can’t do that, so borrow 1 dollar (= 100 cents)
Now you have 100 cents - 95 cents = 5 cents

Dollars: You borrowed 1, so now you have $19 instead of $20
$19 - $14 = $5

So total change = $5.05

✔ Final answer for #4: $5.05

Problem 5:
Martha Monster bought 12 pumpkins.
She lost 4 of them.
How many are left? → SUBTRACT

12 - 4 = 8

✔ Final answer for #5: 8

Final Answer:
1. 13
2. 32
3. 14
4. $5.05
5. 8
