Estimating and Counting Worksheet Grade 2 | Grade1to6.com - Free Printable

Let’s solve each box one by one. We’ll estimate first (guess close to the real number), then count carefully to get the exact number.

---

Box 1 (Top Left – Pink Triangles):
Already done as example:
Estimate = 20, Counted = 18 → Correct.

---

Box 2 (Top Right – Yellow Circles):

Let’s count row by row:

- Row 1: 10 circles
- Row 2: 10 circles
- Row 3: 10 circles
- Row 4: 10 circles
- Row 5: 10 circles
- Row 6: 2 circles on left + 2 on right = 4 circles

Total = 10+10+10+10+10+4 = 54

Estimate: Since it looks like almost 6 full rows of 10, maybe guess 55 or 50. Let’s say 55.

→ Estimate = 55, Counted = 54

---

Box 3 (Second Row Left – Blue Triangles):

Count row by row:

- Row 1: 4 triangles
- Row 2: 5 triangles
- Row 3: 6 triangles

Total = 4 + 5 + 6 = 15

Estimate: Looks like around 15–16. Let’s say 15.

→ Estimate = 15, Counted = 15

---

Box 4 (Second Row Right – Blue Hexagons):

This is a big grid with some missing at bottom right.

Let’s break it into parts:

Left side: Full rectangle? Let’s see height and width.

Actually, better to count column by column or group.

Notice: It’s mostly a 10x10 grid but missing some at bottom right.

Wait — let’s count rows:

Row 1 to Row 9: Each has 10 hexagons → 9 × 10 = 90

Row 10: Only 7 hexagons (missing last 3)

Row 11: Only 4 hexagons (first 4 only)

Wait — actually looking again:

From top:

Rows 1–9: 10 each → 90

Row 10: 7 hexagons (positions 1–7)

Row 11: 4 hexagons (positions 1–4)

But wait — in the image, after row 9, row 10 has 7, row 11 has 4? Actually, let me recount visually.

Alternative way: Total if full 11 rows × 10 = 110

Missing: In row 10, missing 3; row 11, missing 6 → total missing 9

So 110 - 9 = 101

Wait — that doesn’t match visual. Let me count directly.

Actually, let's do it properly:

Looking at the shape:

It’s like a rectangle 10 wide, but bottom right cut off.

Count columns from left:

Column 1: 11 hexagons
Column 2: 11
... up to Column 7: 11 each → 7×11=77

Column 8: 10 (missing bottom one)
Column 9: 9 (missing bottom two)
Column 10: 8 (missing bottom three)

Wait — no, better to count rows:

Row 1: 10
Row 2: 10
Row 3: 10
Row 4: 10
Row 5: 10
Row 6: 10
Row 7: 10
Row 8: 10
Row 9: 10 → that’s 90

Row 10: 7 (only first 7)
Row 11: 4 (only first 4)

So 90 + 7 + 4 = 101

Yes.

Estimate: Looks like about 100. So 100

→ Estimate = 100, Counted = 101

---

Box 5 (Third Row Left – Purple Triangles):

Count row by row:

Row 1: 5
Row 2: 6
Row 3: 7
Row 4: 8
Row 5: 9

Total = 5+6+7+8+9 = let’s add: 5+9=14, 6+8=14, plus 7 → 14+14=28+7=35

Estimate: Around 35. Maybe guess 35

→ Estimate = 35, Counted = 35

---

Box 6 (Third Row Right – Yellow Circles):

Count row by row:

Row 1: 10
Row 2: 10
Row 3: 10
Row 4: 10
Row 5: 10
Row 6: 3 on left + 3 on right = 6

Total = 10×5 = 50 + 6 = 56

Estimate: Almost 6 rows of 10 → guess 55 or 56. Let’s say 55

→ Estimate = 55, Counted = 56

---

Box 7 (Bottom Left – Blue Triangles):

Count row by row:

Row 1: 6
Row 2: 7
Row 3: 6

Total = 6+7+6 = 19

Estimate: Looks like around 20. Guess 20

→ Estimate = 20, Counted = 19

---

Box 8 (Bottom Right – Purple Triangles):

Count row by row:

Row 1: 6
Row 2: 7
Row 3: 8
Row 4: 9
Row 5: 10
Row 6: 3 (at bottom right)

Wait — let’s list:

Row 1: 6
Row 2: 7
Row 3: 8
Row 4: 9
Row 5: 10
Row 6: 3 (only last 3 positions)

Total = 6+7=13; +8=21; +9=30; +10=40; +3=43

Estimate: Looks like about 40–45. Guess 43 or 45. Let’s say 45

→ Estimate = 45, Counted = 43

---

Now, compiling all answers:

Final Answer:

Box 2 (Yellow Circles): Estimate = 55, Counted = 54
Box 3 (Blue Triangles): Estimate = 15, Counted = 15
Box 4 (Blue Hexagons): Estimate = 100, Counted = 101
Box 5 (Purple Triangles): Estimate = 35, Counted = 35
Box 6 (Yellow Circles): Estimate = 55, Counted = 56
Box 7 (Blue Triangles): Estimate = 20, Counted = 19
Box 8 (Purple Triangles): Estimate = 45, Counted = 43
