1) Write & Solve Two-Step Equations Task Cards & QR Codes
- Given real-world problems, students write & solve two-step equations. Because students naturally gravitate towards writing equations that reflect how to go about solving the problem rather than a direct translation of the word problem into a number sentence, students are given half of the equation (the "total") and must write the expression that would make the equation true.
May be implemented in various ways, such as independent or collaborative activity, or may be used in math stations or as guided instruction.
QR codes are a wonderful form of instant feedback for students. Students may compare their equations/solutions with the correct answers to build student confidence when achieving correct solutions, while also challenging students to understand where they went wrong when equations and/or solutions are incorrect.
2) Solve One & Two Step Equations: Error Analysis
- Includes 7 two-step equations with integers & 2 one-step equations with rational (fractions) coefficients that have been worked out incorrectly. Students must identify the step in which an error was made and correct the equation so that a correct solution is reached. Errors made in the equations are common misconceptions & errors that my own kiddos make, so I can only assume yours do too!
Encourages students to communicate mathematically & to analyze problems.
3) Solve One-Step Equations: Scavenger Hunt
- Students work independently or in pairs (depending on fluency/necessary peer scaffolding) to solve nine one-step equations with integers. Problems are posted around the room. I printed mine on bright colored paper so my kids couldn't miss them!! Students may start at any equation, showing work on their recording sheet. Once students reach a solution, they look around the room to find their answer. This leads them to the next equation to be solved. If students reach a solution that is not found in the scavenger hunt, they know that they have done something wrong & should reassess their work/answer. If they get an answer that causes them to repeat a problem, they know they have done something wrong as well. Students will be guided to solve all nine equations if they solve them correctly! Can be used as a means of formative or summative assessment, or as a review!
4) Solve One-Step Equations: Partner Practice
- **10 one step equations including the addition, subtraction, multiplication, and
division of integer constants and coefficients, with the variable on both sides of the
**Includes a student recording sheet & answer key
**In groups of 2, students independently work backwards to solve one step
equations. While students solve different equations, corresponding problems have
the same solution. So, students check their answers with their partner. If students
have different answers, they must go back and look at their work to determine who
is correct and where they or their partner messed up until they agree on an answer.
**Independent practice that encourages peer teaching/scaffolding
