I will write on the board: To keep the equation balanced, I also subtracted from on the right side. I will check for understanding by asking students questions throughout the lesson. This gave me a value of for x.
While the students are working on the independent practice worksheets, I will walk around the room asking them to explain their answers to the problems they are working on.
Remember that we need to keep the equation balanced. I will model this by writing on the board: If I have 5 pounds on one side of the scale, what do I need to have on the other side of the scale for this scale to be balanced?
In the problem that we just did, x was the variable used the represent the quantity that we were looking for. There would be a basic vertical line down beneath the equal sign. To do this, we need to reverse what was done to x in the equation. To keep the equation in balance, I also subtracted 12 from 18 on the right side.
I will explain that equations are just like the scale. Writes for different purposes. I will also randomly select students to answer questions at certain points during the lesson to make sure that the class understands what I am teaching them.
This test will be formally graded using the attached rubric. Both sides of a scale need to be equal to balance, and both sides of an equation need to be equal to balance.
I will be looking for students to acknowledge the idea that it takes an equal distribution of weight on both sides. The student writes in a variety of forms for different audiences and purposes. The students will be instructed to begin working on the problems from the worksheet on their own.
What I do on one side of equation, I must do on the other side. Students will complete the problems on the test. At the end of the lesson, I will ask the students several questions: This gave me a value of 6 for x.The chemical reality of atoms reacting in ratios of small whole numbers is reflected in the final answer.
