Essential Questions:
Why is it that solving equations is such a powerful problem solving tool?
Why learn to solve them?
Big Ideas:
Algebra is the most powerful tool ever invented. Learn to use it's power.
Unit 1 instructional time is focused on these power standards:
8.EE.C.7: Solve linear equations in one variable.
8.EE.C.7.A: Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers).
8.EE.C.7.B: Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.
Unit 2 instruction will be supported by these standards:
8.G.C.9 Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems.
