Go fish
In the “go fish” activity I created an aquarium. It consisted of decorations, gravel, filter, etc… I put several varieties of rocks/gems,plants, background, and a big Eiffel Tower, because Paris is my theme. Also I got fish.. The fish I got were Red Female Veiltail betta. I got 1 of those and it cost 5.26. Then I got the Neon Tetra, I got 2 of them and it was 3.18. I also got the male Halfmoon Betta. I got 1 of those and it was 1.99. Then I got a Australian Rainbow fish. I got 3 of those. It was 7.47. Lastly I got a snail to eat the dirty things away. I had $40.73 left over.
