First Grade Is It an Insect or Arachnid? Sorting Activity - Free Printable

The image you've uploaded appears to be an educational sorting activity titled "Is It an Insect or Arachnid? Sorting". The goal is to classify various animals into two categories: Insects and Not Insects (which includes arachnids and other non-insect creatures).

Let’s break down the task and solve it step by step.

🔍 Key Differences: Insects vs. Arachnids

To correctly sort the animals, we need to understand the biological differences:

| Feature | Insects | Arachnids |
|----------------------|-----------------------------|-----------------------------|
| Body parts | 3 (head, thorax, abdomen) | 2 (cephalothorax, abdomen) |
| Legs | 6 (3 pairs) | 8 (4 pairs) |
| Antennae | Yes | No |
| Examples | Beetles, butterflies, ants | Spiders, scorpions, ticks |

> Note: "Not Insects" includes arachnids (like spiders and scorpions), but also mammals, birds, etc., which are clearly not insects.

🧩 Step-by-Step Sorting

We’ll analyze each animal in the images provided on the right side of the worksheet.

#### ✔ Animals in the Image (Right Side)

1. Hedgehog
- Mammal → Not an insect
- ✘ Not Insect

2. Scorpion
- Arachnid → 8 legs, no antennae
- ✘ Not Insect

3. Butterfly
- Insect → 6 legs, 3 body parts, wings
- ✔ Insect

Now let’s look at the smaller images beneath the tables (the ones meant to be sorted). Since they're grayscale and small, I'll describe them based on typical appearances in such worksheets.

Here are common images found in this type of activity:

#### 🖼️ Common Images (Likely Included):

1. Ant – 6 legs, 3 body segments → ✔ Insect
2. Spider – 8 legs, 2 body parts → ✘ Not Insect
3. Beetle – 6 legs, hard shell → ✔ Insect
4. Fly – 6 legs, wings → ✔ Insect
5. Tick – 8 legs → ✘ Not Insect
6. Centipede – Many legs, long body → ✘ Not Insect (it's a myriapod)
7. Cockroach – 6 legs → ✔ Insect
8. Mantis – 6 legs, raptorial forelegs → ✔ Insect
9. Crab – 10 legs → ✘ Not Insect (crustacean)
10. Ladybug – 6 legs → ✔ Insect
11. Mosquito – 6 legs → ✔ Insect
12. Wolf Spider – 8 legs → ✘ Not Insect
13. Grasshopper – 6 legs → ✔ Insect
14. Scorpion – already shown → ✘ Not Insect
15. Flea – 6 legs → ✔ Insect
16. Wasp – 6 legs → ✔ Insect
17. Snail – No legs, mollusk → ✘ Not Insect
18. Earthworm – Segmented worm → ✘ Not Insect

📝 How to Use the Worksheet

1. Cut out the pictures.
2. Sort each picture into:
- Insects: if it has 6 legs, 3 body parts, and antennae.
- Not Insects: if it has more or fewer than 6 legs, or lacks antennae.

---

💡 Tips for Students

- Count the legs — 6 = insect, 8 = arachnid.
- Look for antennae — only insects have them.
- Remember: spiders, scorpions, ticks, mites are not insects!

✔ Answer Summary (Based on Visible Images)

From the three larger images on the right:
- Hedgehog → Not Insect
- Scorpion → Not Insect
- Butterfly → Insect

So, place:
- Butterfly under Insects
- Hedgehog and Scorpion under Not Insects

For the rest, use the above rules.
