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!

Today in class students completed the Unit 3 Equations Test, and most began the Inequalities Unit by reviewing how to graph inequalities on a number line.
Today in class students took the 20 problem Equations Test. There were 7 bonus problems to try as well.
Today in class students continued to practice writing and solving equations. Test Monday.
Because many students are not completing the homework and getting the practice they need, today in class students slowly worked more on writing equations from word problems. We did not move on to practice multi-step equations.
Today in class students continued their work with their groups solving equations from word problems.
Today in class students worked in groups to deepen their understanding of solving equations from word problems and with variables on both sides of the equal sign.
Today in class students worked on using the distributive property to help solve equations, and we looked at taking apart word problems to create equations and solve them. The steps to solve are the same, and starting to become familiar.
