8.EE.2

8.EE.2. Use square root and cube root symbols to represent solutions to equations of the form //x^2=p// and //x^3=p//, where //p// is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that the square root of 2 is irrational.

- Table for recording the first 15 perfect squares and the first 10 perfect cubes. Planning to introduce by having students use blocks to build squares and cubes.

- Plan to copy onto cardstock and give to students so that they can create a set of flashcards to help them become familiar with perfect squares and cubes.

- Powerpoint to explore square roots and cube roots.
 * [[file:Square and Cube Roots PPT Notes.docx]]- notes sheet to accompany square and cube roots powerpoint
 * [[file:around the world squares and cubes.docx]]- Practice problems for students to complete...hang around the room and have them check in with you as they complete them.
 * [[file:Around the world recording sheet Squares and Cubes.doc]]- recoreding sheet for the around the world squares and cubes activity
 * [[file:Squares and Cubes Practice.docx]]- extra practice for simplifying expressions with squares/cubes/square & cube roots

- Items come from Howard County...different types of tasks...some open ended and some multiple choice or short answer. Most are on the higher level thinking end...

-Task for students to determine which lockers are left open...they are the lockers that have an odd number of factors (the perfect squares)...Good for reviewing factors and introducing what makes a number a perfect square. - exploration for cubes...I have students build the cubes..the volume piece connects with numbers that are perfect cubes. Beyond that students are looking at patterns and making predictions.
 * [[file:Locker Problem Stories.doc]]- after exploration above, tell the story of what happened to the lockers and come up with an additional locker that would be open and an additional one that would be closed.
