Identify and color spheres yellow and cubes green in this educational geometry worksheet.

Let’s go step by step to solve this problem.

We are told to:
- Shade all spheres yellow.
- Shade all cubes green.

First, let’s remember what a sphere and a cube look like:

✔ A sphere is a perfectly round 3D shape — like a ball. It has no flat sides or corners. In the picture, it will look like a circle with some shading to show it’s round (like a marble).

✔ A cube is a 3D shape with 6 equal square faces — like a dice. All its sides are the same size, and all angles are right angles.

Now, let’s go through each shape in the image one by one (row by row):

---

Row 1:
1. First shape → Cube ✔ → shade GREEN
2. Second shape → Cylinder ✘ → not sphere or cube
3. Third shape → Diamond (2D rhombus) ✘ → not 3D, so not sphere or cube
4. Fourth shape → Rectangular prism ✘ → not a cube (sides not equal)

---

Row 2:
5. Fifth shape → Triangular prism ✘
6. Sixth shape → Sphere ✔ → shade YELLOW
7. Seventh shape → Cone ✘
8. Eighth shape → Cube ✔ → shade GREEN

---

Row 3:
9. Ninth shape → Pyramid ✘
10. Tenth shape → Cube ✔ → shade GREEN
11. Eleventh shape → Rectangular prism ✘
12. Twelfth shape → Sphere ✔ → shade YELLOW

---

Row 4:
13. Thirteenth shape → Sphere ✔ → shade YELLOW
14. Fourteenth shape → Cylinder (on side) ✘
15. Fifteenth shape → Tall rectangular prism ✘
16. Sixteenth shape → Cube ✔ → shade GREEN

---

So, let’s list them clearly:

🟡 Spheres to shade YELLOW:
- Row 2, position 2
- Row 3, position 4
- Row 4, position 1

🟩 Cubes to shade GREEN:
- Row 1, position 1
- Row 2, position 4
- Row 3, position 2
- Row 4, position 4

That’s 3 spheres and 4 cubes total.

Final Answer:
Shade these shapes:
→ Spheres (yellow): the 3 ball-shaped objects
→ Cubes (green): the 4 box-shaped objects with all sides equal
