Perfect Math Explanations & Turkey

Sometimes it is really hard to explain our thinking in math. And who knew you could write it down? Well, second graders can! We decided as a group what is the perfect way to write a math explanation in a step by step process. Then we created our own math problems and solved them by EXPLAINING the answer, not just writing a number. Its more important to know what your process of thinking is than what the right answer is.

Below is the mathematical practice for career and college ready standards.

Construct viable arguments. 
Mathematically proficient students understand and use stated assumptions,
definitions and previously established results in constructing arguments. They
make conjectures and build a logical progression of statements to explore the
truth of their conjectures. They break things down into cases and can recognize and use counterexamples. They use logic to justify their conclusions, communicate them to others and respond to the arguments of others. They reason inductively about data, making plausible arguments that take into account the context from which the data arose.

Ecosystems

After visiting the fish hatchery we were able to learn that Pacific Salmon rely on two diverse ecosystems to survive and reproduce. These salmon must reproduce in a shallow water ecosystem and survive in a larger ocean ecosystem. Salmon repeat their migration year after year in order to keep their species alive. This migration is also their life cycle. Check out our comic book strip of a salmon's life cycle and migration though ecosystems.
