AIM: How can we use inequalities to model real-world situations?
HW: Complete problem set below
1. Solve: -x=10
2. Find 2 solutions to: -x>10
3. Solve: 2x=-20
4. Find 2 solutions to: 2x>-20
We focused on using equations to find the "boundary" point for a series of situations today. We then used the equations to help us write inequalities and tested the inequalities with known solutions to make sure they accurately described the situation.
From yesterday...Today was a re-introduction to inequalities. Students were exposed to inequalities last year. We will build upon that understanding by merging our knowledge of distributive property, writing & solving two & 3 step equations.
Today, we looked at inequality representations on a number line and how they apply in real-world contexts. We looked at Noah and his height requirement to ride a roller coaster.
