Variable Both Sides Equations Scaffolded
Solving the variable on both sides is the Cerberus of 1 variable linear equations. It has multiple steps, simplifying expressions, and eliminating a variable expression. The later is a new step, added on to all the other steps. This post describes a scaffolded handout to guide students through the mental steps and the written steps.…

Solve Equations with Like Terms Scaffolded
Many students struggle with solving equations. Many struggle with simplifying expressions. Putting these together becomes an algebraic version or Orthrus (brother to the more famous 3-headed dog, Cerberus). This post shares a scaffolded handout to guide students through the process while making sense of each step. Explanation of Handout The first two are mental steps.…

Solving Equations – Scaffolded Handouts
There are several layers to solving equations that can be unpacked using a task analysis approach. This includes written and mental steps (such as what we teachers mean when we tell a student to do the same thing to “both sides of the equation”). Here is how I develop the concept of equations and solving.…

Concepts vs Skills – Need Both
In general math is taught by focusing on the steps. Conduct a Google search for solving equations and you will see the steps presented (below). You need a video to help your student understand solving and you typically get a presenter standing at the board talking through the examples. (I’ve posted on my approach to…

Introduction to Equations – (Meaning Making)
This is a meaning making approach to introducing equations. I will walk through the parts shown in the photo in the space below this photo. (A revised edition of this handout will be used in a video on this topic.) First I explain the difference between an expression (no =) and an equation (has =).…

Evaluating the Effectiveness of Math Objectives
The math objectives present in the photos on this post were written for former students of mine. These types of objectives are ineffective and ubiquitous. When I have sat in IEP meetings the majority of the time I am the only person who is capable of evaluating IEP math objectives. This post provides some guidance…
