             Learning Intention: 

What? We are learning how to identify the parts of a chemical equation.

Why?  In order to identify the number of atoms and molecules in a chemical equation.  

             Success Criteria

In a Chemical Equation, I can: 

- Identify the reactants and products 

- Identify coefficients and subscripts

- Identify the amount atoms

-Identify the amount of molecules
