Summer Activity Sheets — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Jake found 9 seashells and his sister found 6 more. They found 15 seashells together.
To find the total of both kids' shells, add their counts together: 9 + 6 = 15 seashells.
2. Sand, water, and waves are found at the beach.
A beach is the strip of sand right where the ocean meets the land, so sand, water, and waves all come together in that one spot.
3. 17 sandcastles minus 8 sandcastles equals 9 sandcastles.
Removing 8 sandcastles from 17 leaves 9, since 17 - 8 = 9 (and 9 + 8 = 17 confirms it).
4. An umbrella at the beach gives you shade.
A beach umbrella blocks the sun's rays from reaching the ground beneath it, creating a cool, shady spot where you can rest out of the heat.
5. 7 plus 6 equals 13.
7 + 6 = 13. A doubles trick: 6 + 6 = 12, and one more makes 13.
6. The salty water in the ocean is called saltwater.
The ocean has a lot of dissolved salt in it, which is why people call it saltwater to tell it apart from the freshwater in lakes and rivers.
7. 14 minus 5 equals 9.
14 - 5 = 9. You can count back 5 from 14 (13, 12, 11, 10, 9) to land on 9.
8. A large wave that surfers ride is called a wave.
A wave is the moving hill of water that rises up and rolls toward shore, and surfers ride on it by standing on a board as it pushes them forward.
9. 9 plus 8 equals 17.
9 + 8 = 17. One trick is to think 10 + 8 = 18, then take one away to get 17.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each ocean animal to its description.
Dolphin
→ A smart sea mammal that jumps out of the water
A sea creature with a soft body that can sting
Starfish
→ A star-shaped animal that lives on the ocean floor
A reptile with a hard shell that swims in the ocean
Sea turtle
→ A reptile with a hard shell that swims in the ocean
A smart sea mammal that jumps out of the water
Jellyfish
→ A sea creature with a soft body that can sting
A star-shaped animal that lives on the ocean floor
Dolphins are clever mammals that leap above the waves, starfish have five arms and cling to the sea floor, sea turtles are reptiles protected by a hard shell, and jellyfish drift with soft bodies and stinging tentacles.
