Critical Thinking & Problem Solving Effective Communication CCSS.Math.Content.6.G.A.2 Assessment Reflection Core Content Project Launch Essential Question Submission Required

Students watch a short pet store order scenario, inspect 2-3 rectangular prism aquarium models or paper nets, and discuss the two driving questions about water capacity and material efficiency. In teams, they estimate which tank holds more water and which uses less material, then record one measurable criterion, one constraint, and one first-draft sketch in their Aquarium Design Notebook. The class closes with a brief share-out of design trade-offs and an exit ticket naming one design change they would make and one math idea that would guide it.

#	What teachers do
1	Launch the challenge by showing the short pet store aquarium order scenario, then introduce the two essential questions and ask students to listen for the design needs involving water capacity, fish space, shape, and material use. (7 min)
2	Place students in teams to inspect 2-3 rectangular prism aquarium models or paper nets, notice dimensions and faces, and make quick estimates about which tank might hold more water and which might use less material. (10 min)
3	Guide teams to discuss and record evidence from the models by identifying one measurable criterion, one constraint, and one likely trade-off connected to the fish home challenge. (8 min)
4	Have teams create a first-draft aquarium sketch in their Aquarium Design Notebook with labeled dimensions they think could meet the tank goal, and add a brief written justification for why their shape may balance capacity and material efficiency. (10 min)
5	Facilitate a brief class share-out where teams present one design choice, one trade-off they noticed, and one question they still have about volume or material use. (5 min)
6	Close with an individual exit ticket in which students name one design change they would make to their sketch and one math idea that would guide that change. (5 min)

Preparation (8 items)

Prepare and test a short pet store aquarium order scenario video, slide, or read-aloud that clearly includes needs related to water capacity, fish space, and material use.
Gather 2-3 rectangular prism aquarium models or paper nets with visibly different dimensions so students can compare likely volume and material use.
Label each model or net with dimensions or provide dimension cards that teams can reference during discussion and sketching.
Set up team supply bins with notebooks, pencils, rulers, and colored pencils or markers for first-draft sketches.
Create a recording space in the Aquarium Design Notebook or on a handout for criterion, constraint, trade-off, and first-draft sketch notes.
Prepare the two essential questions where all students can see them during the lesson.
Create an exit ticket prompt asking for one design change and one math idea that would guide that change.
Arrange tables so teams can easily examine models, talk, and participate in a short end-of-class share-out.

Student-facing instructions

You will work with your team to launch the Fish Home Challenge by studying a pet store aquarium order and comparing sample tank models or paper nets. First, watch or listen to the scenario and pay attention to what the fish need, how much water the tank should hold, and why material use matters. Then, examine the sample rectangular prism tanks with your team. Use the models, dimensions, and faces to estimate which design holds more water and which design may use less material. In your Aquarium Design Notebook, record one measurable criterion your design must meet, one constraint you need to work within, and one trade-off you notice. Next, make a first-draft sketch of a rectangular prism aquarium with labeled dimensions and a short note explaining why you think your design is a good starting point. You will need your notebook, pencil, ruler, and the sample models or nets. At the end, you will share one design idea with the class and complete an exit ticket naming one design change you would make and one math idea that would guide that change. The goal is to begin an evidence-based aquarium design that connects tank dimensions to water capacity and material efficiency.

Success criteria

You are successful when you can: identify at least one need from the fish home scenario related to capacity, fish space, or material use; contribute to your team discussion by comparing at least two sample tank designs; record one measurable criterion and one realistic constraint in your notebook; complete a first-draft rectangular prism aquarium sketch with labeled dimensions; explain one trade-off between holding more water and using less material; share one idea or question during the class discussion or with a partner; and complete an exit ticket that names one design change and one math idea that would guide it.

Facilitator notes

Keep the pace brisk so students spend most of the period handling models, discussing ideas, and sketching rather than listening for too long. Emphasize estimation and reasoning on day 1 rather than exact computation; this supports the later transition to volume formulas in CCSS.Math.Content.6.G.A.2. Prompt students to use language such as holds more water, uses more material, taller, wider, longer, and more faces exposed. If students confuse volume and surface area, redirect with concrete questions such as Which tank gives more inside space for water? and Which tank needs more outside material to build? Support adolescent engagement by assigning quick team roles such as reader, model handler, recorder, and spokesperson. Encourage all students to speak during team talk and ask them to respond to a peer's reasoning before finalizing their own idea. For students who need support, provide sentence starters like Our criterion is..., One constraint is..., and We think this tank holds more water because.... For students ready for more challenge, ask them to compare two tanks with the same volume but different dimensions or to predict how changing one dimension affects material use. Watch for unlabeled sketches, vague criteria such as good tank, and constraints that are not measurable; push students to be specific. Give a 2-minute warning before the share-out and before the exit ticket so notebooks are complete.
