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

Problem Overview:

The task involves estimating and counting the number of shapes in each box. The goal is to fill in the "Estimate" and "Counted" values for each set of shapes.

Solution Approach:

1. Estimation: Make a rough guess of the number of shapes based on visual inspection.
2. Counting: Carefully count the actual number of shapes in each box.

Let's solve each section step by step.

---

Box 1 (Top Left): Pink Triangles

- Estimate: 20
- Counted: 18

This one is already filled in as an example.

---

Box 2 (Top Right): Yellow Circles

- Estimate: ~30 (There are about 5 rows with 6 circles each, so roughly \(5 \times 6 = 30\)).
- Counted: 32 (Carefully count each circle: 5 rows of 6 circles plus 2 extra circles at the bottom).

So, the answers are:
- Estimate: 30
- Counted: 32

---

Box 3 (Middle Left): Blue Triangles

- Estimate: ~20 (There are about 4 rows with 5 triangles each, so roughly \(4 \times 5 = 20\)).
- Counted: 20 (Carefully count each triangle: 4 rows of 5 triangles).

So, the answers are:
- Estimate: 20
- Counted: 20

---

Box 4 (Middle Right): Blue Hexagons

- Estimate: ~50 (There are about 10 columns with 5 hexagons each, so roughly \(10 \times 5 = 50\)).
- Counted: 50 (Carefully count each hexagon: 10 columns of 5 hexagons).

So, the answers are:
- Estimate: 50
- Counted: 50

---

Box 5 (Bottom Left, Top Row): Red Triangles

- Estimate: ~30 (There are about 6 rows with 5 triangles each, so roughly \(6 \times 5 = 30\)).
- Counted: 31 (Carefully count each triangle: 6 rows of 5 triangles plus 1 extra triangle).

So, the answers are:
- Estimate: 30
- Counted: 31

---

Box 6 (Bottom Right, Top Row): Yellow Circles

- Estimate: ~40 (There are about 8 rows with 5 circles each, so roughly \(8 \times 5 = 40\)).
- Counted: 42 (Carefully count each circle: 8 rows of 5 circles plus 2 extra circles).

So, the answers are:
- Estimate: 40
- Counted: 42

---

Box 7 (Bottom Left, Bottom Row): Blue Triangles

- Estimate: ~25 (There are about 5 rows with 5 triangles each, so roughly \(5 \times 5 = 25\)).
- Counted: 25 (Carefully count each triangle: 5 rows of 5 triangles).

So, the answers are:
- Estimate: 25
- Counted: 25

---

Box 8 (Bottom Right, Bottom Row): Red Triangles

- Estimate: ~35 (There are about 7 rows with 5 triangles each, so roughly \(7 \times 5 = 35\)).
- Counted: 36 (Carefully count each triangle: 7 rows of 5 triangles plus 1 extra triangle).

So, the answers are:
- Estimate: 35
- Counted: 36

---

Final Answers:

1. Top Left: Estimate = 20, Counted = 18
2. Top Right: Estimate = 30, Counted = 32
3. Middle Left: Estimate = 20, Counted = 20
4. Middle Right: Estimate = 50, Counted = 50
5. Bottom Left, Top Row: Estimate = 30, Counted = 31
6. Bottom Right, Top Row: Estimate = 40, Counted = 42
7. Bottom Left, Bottom Row: Estimate = 25, Counted = 25
8. Bottom Right, Bottom Row: Estimate = 35, Counted = 36

Boxed Final Answer:

\[
\boxed{
\begin{array}{ll}
\text{Top Right:} & \text{Estimate = 30, Counted = 32} \\
\text{Middle Left:} & \text{Estimate = 20, Counted = 20} \\
\text{Middle Right:} & \text{Estimate = 50, Counted = 50} \\
\text{Bottom Left, Top Row:} & \text{Estimate = 30, Counted = 31} \\
\text{Bottom Right, Top Row:} & \text{Estimate = 40, Counted = 42} \\
\text{Bottom Left, Bottom Row:} & \text{Estimate = 25, Counted = 25} \\
\text{Bottom Right, Bottom Row:} & \text{Estimate = 35, Counted = 36}
\end{array}
