"I used this with my 3rd graders. It was engaging! We didn't get through the whole thing yet, but I do wish the grid paper was a little larger. I wish they could have created an array for 24 with a 12 x 2, but the grid paper is only a 10 x 10. Overall, it's a great activity and kept attention! :) "

Description

This project-based learning task has students practice multiple third grade math skills as they dive into running an aquarium.

First, students must give their aquarium a name and a motto that will appeal to their visitors.

Next, they need to design the different tanks for the exhibits. To do this, they are given either an area the tank must be or perimeter. They come up with different possibilities for what the tanks will look like, then make a decision on which tank design they think works best and put all of their tanks on the aquarium floor plan.

Students then solve a beginner logic puzzle in order to figure out which fish can live in smaller tanks together.

Then, students need to practice with multi-digit addition skills in order to fill their tanks with different types of decorations.

Students practice elapsed time by creating a schedule of events happening at their aquarium.

Finally, students practice multiplication skills by setting an admission price and figuring out how much money it will cost for different groups to visit the aquarium.

This is a great project to use for enrichment for math. At my school, we do Universal Access time and I have a small group of on-/above- grade level students working independently in my classroom while I work with a larger group of students who are below grade level. This works perfectly to keep them engaged and on-task, but also challenged. I will definitely be buying more of these math projects from this Author! Thank you!
