CCSS.Math.Content.8.EE.C.7b: Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.
CCSS.Math.Content.HSA-REI.B.3: Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
Solving equations is a foundational skill needed in pre-algebra and algebra. Being able to solve a variety of equations enables students to analyze functional relationships.
Students need practice in solving equations in order to develop fluency in uncovering unknown values.
In this activity there are 10 multi-step equations embedded in QR Codes. The equations require simplifying but have variables only on one side. The activity works as a scavenger hunt ... students find QR codes posted in the classroom or school hallways. Students use their phones to read the QR codes to get the problems. They solve equations with their partners. A recording sheet and answer key is included.
