Here is the step-by-step solution to complete the worksheet.

Step 1: Label the Insect Parts

First, we need to match the words in the box to the correct parts of the insect diagram. Looking at the drawing from top to bottom and outside to inside:

1. Antennae: The two long feelers on the very top of the head.
2. Head: The top section where the eyes and antennae are attached.
3. Eyes: The large circles on the side of the head.
4. Thorax: The middle section of the body where the legs and wings attach.
5. Wings: The large structures attached to the thorax used for flying.
6. Legs: The six limbs attached to the thorax (three on each side).
7. Abdomen: The large rear section of the body.
8. Stinger: The sharp point at the very end of the abdomen.

Step 2: Complete the Sentences

Now we use those labels to fill in the blanks in the sentences provided below the insect.

Sentence 1: "An insect's \_\_\_\_\_\_ includes the \_\_\_\_\_\_, \_\_\_\_\_\_, and \_\_\_\_\_\_."
* *Logic:* An insect's body is divided into three main sections. Based on the diagram, these are the Head, Thorax, and Abdomen.
* *Answer:* An insect's body includes the head, thorax, and abdomen.

Sentence 2: "Three pairs of \_\_\_\_\_\_ are connected to the \_\_\_\_\_\_."
* *Logic:* "Three pairs" equals six items. Insects have six legs. Looking at the diagram, the legs attach to the middle section.
* *Answer:* Three pairs of legs are connected to the thorax.

Sentence 3: "Most insects have one or two pair of \_\_\_\_\_\_."
* *Logic:* Most flying insects have wings.
* *Answer:* Most insects have one or two pair of wings.

Sentence 4: "The tip of the \_\_\_\_\_\_ may have a tube for laying eggs or a \_\_\_\_\_\_."
* *Logic:* The rear part of the insect is the abdomen. The sharp part at the very end is the stinger.
* *Answer:* The tip of the abdomen may have a tube for laying eggs or a stinger.

Step 3: Solve the Number Code

To solve the final section, we assign a number to each letter based on its position in the alphabet (A=1, B=2, C=3, etc.).

Code Key:
* A = 1
* B = 2
* C = 3
* D = 4
* E = 5
* F = 6
* G = 7
* H = 8
* I = 9
* J = 10
* K = 11
* L = 12
* M = 13
* N = 14
* O = 15
* P = 16
* Q = 17
* R = 18
* S = 19
* T = 20
* U = 21
* V = 22
* W = 23
* X = 24
* Y = 25
* Z = 26

Decoding Sentence 1:
`20-8-5-18-5` `1-18-5` `13-15-18-5` `20-8-1-14` `1-13-9-12-12-9-15-14` `11-9-14-4-19` `15-6` `9-14-19-5-3-20-19.`

* 20-8-5-18-5 = T-H-E-R-E
* 1-18-5 = A-R-E
* 13-15-18-5 = M-O-R-E
* 20-8-1-14 = T-H-A-N
* 1-13-9-12-12-9-15-14 = A-M-I-L-L-I-O-N
* 11-9-14-4-19 = K-I-N-D-S
* 15-6 = O-F
* 9-14-19-5-3-20-19 = I-N-S-E-C-T-S

*Result:* There are more than a million kinds of insects.

Decoding Sentence 2:
`20-8-5` `7-15-12-9-1-20-8`

* 20-8-5 = T-H-E
* 7-15-12-9-1-20-8 = G-O-L-I-A-T-H

*Result:* The Goliath...

Decoding Sentence 3:
`1-20-12-1-19` `13-15-20-8`

* 1-20-12-1-19 = A-T-L-A-S
* 13-15-20-8 = M-O-T-H

*Result:* An Atlas moth...
