Debug Glitchy™: Fraction Operations Error Analysis | Math Mistakes
Students can follow steps. But can they catch a mistake — and explain exactly why it's wrong? Debug Glitchy gives students 12 carefully designed error analysis problems covering all four fraction operations. In each problem, Glitchy — a robot with a math bug — shows his work. Students identify where the reasoning breaks down, explain the error, and show the correct solution. What's Included: 12 error analysis problems (3 addition, 3 subtraction, 3 multiplication, 3 division), student worksheet,

3 Digit by 3 Digit Addition Algorithm Steps | Anchor Chart + Student Version
Teaching the standard algorithm for 3-digit addition can feel simple… until regrouping shows up and half the class freezes. I created this step-by-step visual because my students needed something clear, predictable, and consistent to reference — without me reteaching it every time. This resource breaks down 3-digit by 3-digit addition with regrouping into manageable steps that students can actually follow independently. The anchor chart version is perfect for your math wall, and the student vers
