Find the Nets Sheet 1: Identify and shade the correct net for each 3D shape.

I'll solve this "Find the Nets" worksheet by identifying the correct 2D net for each 3D shape shown.

Let me go through each row one by one:

Row 1: Cube
- The 3D shape is a cube (a square prism with all sides equal).
- A cube has 6 square faces.
- Looking at the options, the first net (cross-shaped with 6 squares) is the classic net for a cube.
- The second net has triangles and a square, which would form a pyramid, not a cube.
- The third net has rectangles and circles, which doesn't match a cube.

Row 2: Cylinder
- The 3D shape is a cylinder.
- A cylinder has 2 circular bases and 1 rectangular lateral surface that wraps around.
- The first option shows a rectangle with a circle on top and bottom - this is the correct net for a cylinder.
- The second option is similar but the circles are positioned differently.
- The third option is a star-like shape, which doesn't correspond to a cylinder.

Row 3: Rectangular Prism
- The 3D shape is a rectangular prism (not a cube, since the sides have different lengths).
- It has 6 rectangular faces (or sometimes 4 rectangles and 2 squares if it's a special case).
- The first net shows 6 rectangles arranged in a way that can fold into a rectangular prism.
- The second net is the same as the cube net, which wouldn't work for a rectangular prism with different side lengths.
- The third net has triangles, which would form a pyramid.

Row 4: Square Pyramid
- The 3D shape is a square pyramid (base is a square, sides are triangles).
- It has 1 square base and 4 triangular faces.
- The first net shows a square with 4 triangles attached to its sides - this is the correct net for a square pyramid.
- The second net is the cube net again.
- The third net has rectangles and triangles, which doesn't match.

Row 5: Triangular Prism
- The 3D shape is a triangular prism (bases are triangles, sides are rectangles).
- It has 2 triangular bases and 3 rectangular faces.
- The first net shows 3 rectangles with triangles on the ends - this is the correct net for a triangular prism.
- The second net has hexagons and squares, which doesn't match.
- The third net has triangles and a square, which would form a pyramid.

Based on my analysis, here are the correct nets for each 3D shape:

1. Cube: First net (cross-shaped with 6 squares)
2. Cylinder: First net (rectangle with circles on top and bottom)
3. Rectangular Prism: First net (6 rectangles arranged appropriately)
4. Square Pyramid: First net (square with 4 triangles attached)
5. Triangular Prism: First net (3 rectangles with triangles on the ends)

The correct answer for each row is the first option in that row.
