Day 46: Write and Solve + and - Equations / Coordinate Plane

Math 6 students worked with Lesson 4.3: Write and Solve Addition and Subtraction Equations. We will discuss incorporating the inverse operation to solve one-step equations. Students are then going to learn how to substitute their answer back into the equation to determine if they have correctly calculated the solution of the equation.

A special shout out to Hess on the last day of the 1st quarter.

Math 6+ students worked with quadrants and order pairs today. This is will tie in nicely as we begin to graph linear equations in the coming weeks.

Standards addressed in class today:

Math 6:

• Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.
• Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.

Math 6+:

• Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.
