Today in class students completed the Inequalities Test and began a review of rational numbers to prepare to do test corrections on the Unit 2 test. Review of Multiplying and Dividing Fractions www.brainpop.com/math/numbersandoperations/multiplyinganddividingfractions/ Review of Adding and Subtracting Fractions
www.brainpop.com/math/numbersandoperations/addingandsubtractingfractions/ Today in class students took the Inequalities Unit Test.
Today in class students solved more inequalities in preparation for the Inequalities Test tomorrow.
Answers to HW: 4. r > 2 10. b < - 3 5. p < - 1 11. a > 11 6. m < 0 12. n < 4 7. x < - 12 13. k < - 2 8. v < 10 14. x < 0 9. n > 1 Today in class students found that they can distribute and combine like terms across an inequality symbol. We practiced several problems with our groups.
Answers to HW: 13. a > - 3 17. n > 1 14. v > 6 18. p > 3 15. n > - 4 19. k < 7 16. x > 2 20. x > 0 Today in class students worked on multi-step inequalities.
Answers to HW: 1. n < - 1 4. k < 2 2. x < 1 5. m > - 5 3. p < 2 6. x < 3 Today in class students ignored me as I reviewed how to solve two step equations - which works for inequalities with the additional rule of turning around the inequality symbol when you multiply or divide with a negative number to find the solution set. I showed how to use the number line to graph and plug in possible solutions that make the inequality true. Students continued to ignore me as I demonstrated that the rule for turning around the inequality symbol does not have anything to do with adding or subtracting negatives in the inequality - ONLY multiplying and dividing.
Today in class students practiced solving inequalities using multiplication and division. They remembered that when multiplying and dividing with a negative means you must flip the inequality symbol around to represent the correct solution set.
Today in class students learned how we use inequalities, how we write inequalities, and how they are the same, and different, from equations.
Today in class students discovered that solving inequalities is a lot like solving equations!
