Halloween Math & Reading — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Spiders belong to a group called arachnids, not insects.
Arachnids include spiders, scorpions, and ticks. They have 8 legs, unlike insects which have 6.
2. Unlike insects with six legs, spiders have eight legs.
All arachnids (spiders, scorpions, ticks, mites) have eight legs.
3. Bats are the only mammals that can truly fly.
Bats are the only mammals with true powered flight. Flying squirrels glide but don't truly fly.
4. Bats use echolocation to navigate in the dark by sending out sound waves.
Bats emit ultrasonic sounds and listen to echoes to locate objects and prey in complete darkness.
5. Animals that are active at night and sleep during the day are called nocturnal.
Nocturnal animals (bats, owls, raccoons) are most active at night. Diurnal animals are active by day.
6. A spider's body has two main parts: the abdomen and the cephalothorax.
The cephalothorax is the fused head and thorax region of a spider. The abdomen is the rear section.
7. Most spiders produce silk to build webs and catch prey.
Spider silk is incredibly strong for its weight. Spiders use it for webs, egg sacs, and travel lines.
8. Bats help farmers by eating large numbers of insects that damage crops.
A single bat can eat hundreds of insects per hour, including mosquitoes and crop pests — making them valuable.
9. The scientific study of spiders is called arachnology.
Arachnology is the branch of zoology that studies arachnids (spiders, scorpions, ticks, mites).
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Bats hunt at night
→ nocturnal
echolocation
Spiders have 8 legs
→ arachnid
arachnid
Bats find prey using sound
→ echolocation
nocturnal
Spiders catch food in webs
→ silk
