Grade 1 Geometry Worksheet: Match 2D shapes to their names.

Problem Description:

The task is to match each 2-dimensional shape with its correct name. The shapes provided are:

1. A circle
2. A triangle
3. A square
4. A rectangle
5. An oval
6. A diamond

The names given are:
- Square
- Oval
- Circle
- Diamond
- Triangle
- Rectangle

Solution:

#### Step 1: Identify Each Shape
Let's analyze each shape one by one and determine its correct name.

1. First Shape (Top Left):
- This shape is a perfect round figure.
- Name: Circle

2. Second Shape (Second Row, Left):
- This shape has three straight sides and three angles.
- Name: Triangle

3. Third Shape (Third Row, Left):
- This shape has four equal sides and four right angles.
- Name: Square

4. Fourth Shape (Fourth Row, Left):
- This shape has four sides with opposite sides equal and parallel, but the angles are not necessarily right angles.
- Name: Rectangle

5. Fifth Shape (Fifth Row, Left):
- This shape is an elongated circle or ellipse.
- Name: Oval

6. Sixth Shape (Bottom Left):
- This shape has four equal sides and angles that are not right angles.
- Name: Diamond

#### Step 2: Match Shapes with Names
Now, we can draw lines between the shapes and their corresponding names:

1. Circle → Circle
2. Triangle → Triangle
3. Square → Square
4. Rectangle → Rectangle
5. Oval → Oval
6. Diamond → Diamond

Final Answer:

The matches are as follows:

- Circle → Circle
- Triangle → Triangle
- Square → Square
- Rectangle → Rectangle
- Oval → Oval
- Diamond → Diamond

Boxed Answer:
\[
\boxed{
\text{Circle → Circle, Triangle → Triangle, Square → Square, Rectangle → Rectangle, Oval → Oval, Diamond → Diamond}
}
\]
