Lesson Comments
Today's Math enrichment session with Colson focused upon the important topic of Slope of a Straight Line. Colson was very attentive and worked diligently to practice the method of determining slope from the key formula provided. We also reviewed an exponent law which he was familiar with.
Today's enrichment focused on using a ruler and odd and even numbers which were questions Jason struggled with from the readiness assessment. After discussing and exploring the ruler, Jason measured items from his desk to the nearest inch. Then, we drew with markers on the whiteboard to model the numbers 1 through 10 before pairs were circled to show if each number was even or odd.
We played an algebra curriculum mastery game. This game was designed to help students master standards such as linear and algebraic equations and inequalities. We also covered functions, set theory, and rational operations.
Kaitlin worked on Transforming formulas. She practiced solving a given formula for a given variable. Then we learned to use formulas to solve problems. We learned to solve simple-interest problems. Then we learned that the rate for simple interest is the annual percentage rate (APR), or the percent used to calculate interest that is paid in one year. We learned that in simple interest calculations using the formula I = prt, t represents time as a fraction of a year.
Solving Two-Step Inequalities – We learned that solving two-step inequalities is almost the same as solving two-step equations. The difference is when you multiply or divide each side of an inequality by a negative number you must also reverse the inequality symbol.
Solving Equations with Variables on Both Sides – We learned to solve equations and problems with variables and constants on both sides of the equal sign. We practiced getting the variable terms on one side of the equation using inverse operations. We reviewed how to use the distributive property to solve equations.
