35 Meaningful Second Grade Math Games Your Students Will Love - Free Printable

Let’s solve the problems on the yellow “Number Search” sheet step by step.

We are given a list of subtraction problems on the right side, and we need to solve each one. Then, we’ll look for those answers in the grid (but since you didn’t ask us to find them in the grid, we’ll just solve the math problems).

Here are the problems:

0 - 0 =
1 - 1 =
2 - 2 =
3 - 3 =
4 - 4 =
5 - 5 =
6 - 6 =
7 - 7 =
8 - 8 =
9 - 9 =

And also:

10 - 10 =
11 - 11 =
12 - 12 =
13 - 13 =
14 - 14 =
15 - 15 =
16 - 16 =
17 - 17 =
18 - 18 =
19 - 19 =

Wait — actually, looking again at the image layout, it seems like the problems are written as:

Left column:
0·0–__ → probably means 0 - 0
1·1–__ → 1 - 1
... up to 9·9–__

Right column:
10·10–__ → 10 - 10
11·11–__ → 11 - 11
... up to 19·19–__

But that doesn’t make sense because 10·10 would be multiplication, but the directions say “solve the problems”, and the example says “you will add the + and –”. Wait — let me re-read the directions.

Directions: “Solve the problems, then find and circle the problems hidden in the puzzle. You will add the + and -.”

Hmm — maybe the dot is not multiplication? Maybe it’s just separating numbers? Like “0 - 0” is written as “0·0–__”? That seems odd.

Wait — looking at the top left of the grid, there’s a box with “0 · 0 = 0” — so maybe the dot IS multiplication? But then why does it say “add the + and -”?

Actually, let’s check the very first problem shown in the grid: “0 · 0 = 0” — that’s multiplication.

But then the problems on the right are written as “0·0–__”, which might mean “0 × 0 = ?” and then subtract something? No, that doesn’t fit.

Wait — perhaps the “·” is just a separator, and the problem is “0 - 0”, “1 - 1”, etc., and the “–__” is where you write the answer.

Looking at the example in the grid: they have “0 · 0 = 0” inside a box — that’s clearly 0 times 0 equals 0.

But then the problems listed on the right are “0·0–__”, “1·1–__”, etc. — if it’s multiplication, then 0×0=0, 1×1=1, 2×2=4, etc.

But the directions say “you will add the + and -” — that suggests addition and subtraction, not multiplication.

This is confusing.

Wait — let’s look at the orange sheet behind — it has problems like “8·5–__”, “1·7–__”, “5·6–__”, “2·7–__”, “10·0–__”

If these are multiplications: 8×5=40, 1×7=7, 5×6=30, 2×7=14, 10×0=0 — that makes sense.

And the pink sheet has “12·5–__”, “10·9–__”, “16·8–__” — 12×5=60, 10×9=90, 16×8=128 — also makes sense.

So likely, the “·” means multiplication.

Then what does “you will add the + and -” mean? Maybe it’s a mistake, or maybe it refers to something else.

Perhaps after solving the multiplication, you have to do something with + and -, but the main task is to solve the multiplication problems.

Given that, and since the user asked to solve the problem accurately, I think we should solve the multiplication problems as written.

So for the yellow sheet, the problems are:

Left column:
0 · 0 = ?
1 · 1 = ?
2 · 2 = ?
3 · 3 = ?
4 · 4 = ?
5 · 5 = ?
6 · 6 = ?
7 · 7 = ?
8 · 8 = ?
9 · 9 = ?

Right column:
10 · 10 = ?
11 · 11 = ?
12 · 12 = ?
13 · 13 = ?
14 · 14 = ?
15 · 15 = ?
16 · 16 = ?
17 · 17 = ?
18 · 18 = ?
19 · 19 = ?

These are all squares of numbers from 0 to 19.

Let’s calculate them one by one.

0 × 0 = 0
1 × 1 = 1
2 × 2 = 4
3 × 3 = 9
4 × 4 = 16
5 × 5 = 25
6 × 6 = 36
7 × 7 = 49
8 × 8 = 64
9 × 9 = 81

10 × 10 = 100
11 × 11 = 121
12 × 12 = 144
13 × 13 = 169
14 × 14 = 196
15 × 15 = 225
16 × 16 = 256
17 × 17 = 289
18 × 18 = 324
19 × 19 = 361

I double-checked a few:

- 7×7: 7+7=14, 14+7=21, 21+7=28, 28+7=35, 35+7=42, 42+7=49 → yes.
- 12×12: 10×12=120, 2×12=24, 120+24=144 → correct.
- 19×19: 20×19=380, minus 19=361 → correct.

All seem accurate.

Now, the directions say “then find and circle the problems hidden in the puzzle” — meaning in the grid of numbers, you have to find these products (like 0,1,4,9,16,...) and circle them. But since the user didn’t ask for that part, and only said “solve the problem”, I think we just need to provide the answers to the multiplication problems.

Also, note that in the grid, there’s an example: “0 · 0 = 0” is already filled in, which matches our calculation.

So, final answers for the problems on the yellow sheet are:

For left column (0 to 9 squared):
0, 1, 4, 9, 16, 25, 36, 49, 64, 81

For right column (10 to 19 squared):
100, 121, 144, 169, 196, 225, 256, 289, 324, 361

Since the problem is presented as “0·0–__”, etc., we fill in the blanks with these values.

Final Answer:
0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361
