Systems of Equations too Inequalities INB Pages

My Algebra 1 students only finished our unit of measurement on systems of equations together with inequalities. This unit of measurement wasn't perfect. I'd similar to include a real-world applications when nosotros solve past times graphing. But, compared to previous years, I experience genuinely adept nigh this unit!

The unit of measurement started out amongst a divider. You tin acquire to a greater extent than nigh these dividers here.

Originally, I had planned on breaking this unit of measurement into 4 skills. I genuinely alone ended upwards breaking it into iii skills because I combined SY2 together with SY4 together. Of course, I didn't realize this until it became fourth dimension to firstly SY4. All of a sudden, I realized nosotros had already done it!

Here's a close-up of our skills for the unit:

We started past times practicing our arrangement writing skills.

Then, nosotros solved systems of equations together with inequalities past times graphing.

Then, nosotros finished off our unit of measurement amongst solving systems algebraically.

We did 4 examples together of solving past times substitution. I LOVE how this graphic organizer I made turned out!

When ane or both of the equations would move already solved for ane of the variables, my students seemed to convey a difficult fourth dimension realizing this. For this problem, they kept quest if nosotros could solve for p.

My students kept wanting to purpose the variables they had defined inward their terminal solution sentences. I had to perish along telling them to write a judgement that would brand their English linguistic communication instructor happy. I told them I doubted that their English linguistic communication instructor would desire to run into a variable together with an equal sign inward their equation!

Next, nosotros explored solving systems past times elimination.

When I solve systems, I almost ever prefer to solve them past times elimination. I was surprised, then, when I realize the graphic organizer I had made for elimination had to a greater extent than steps than the graphic organizer for substitution.

Even though at that topographic point are to a greater extent than steps, my students ended upwards preferring the elimination method, too.
