One-Step Equations Progress Monitoring Probes

About this resource

One skill, start to finish. A one-step-equations IEP goal for solving for x with addition, subtraction, multiplication and division, six equivalent probe forms that measure it, and a graph scaled to the probe. Baseline on Monday, goal written by Tuesday, first data point on Friday.

This store's word-problem and multiplication-algorithm probes measure arithmetic: a correct answer only needs the right operation performed on two given numbers. Solving a one-step equation needs one more decision the arithmetic probes never ask for: recognizing the operation printed on the page and performing its INVERSE to isolate x, the way x+5=21 is undone by subtracting 5 from 21, not by adding them. Doing the operation shown instead of its inverse is the single most common error on this skill, and it looks the same way whether the equation is addition, subtraction, multiplication or division, which is why this probe puts all four on one page instead of four separate single-operation probes.

WHAT IS INCLUDED - 18 pages, six probe forms, FIELDS_TBD type-in fields, a binder cover and divider tabs, a family update page, a two-page teacher answer key

A Binder Cover And Divider Tabs

• A binder cover with student, case manager and school year fields, cut and slide into a binder front or folder tab
• Six divider tabs, one per section of this file, print and cut

The Goal Page

• What the probe measures, in one paragraph
• A sample goal, invented, with every bracket meant to be edited by the team
• The six-part goal frame as type-in fields: by (date), given, student will, criterion, on ___ of ___ consecutive probes, as measured by
• A baseline table: three probes and the median
• Three benchmark rows with target date, target score, actual score and met
• The administration and scoring directions
• Lines for this student's own scoring rules, and a box for what the errors say to reteach

Six Probe Forms, A Through F

• Ten one-step equations per form in two labeled groups of five: Addition & Subtraction (three addition equations, two subtraction) and Multiplication & Division (three multiplication equations, two division)
• Every equation is solved by the INVERSE of the operation printed, never the operation shown, so the page never rewards performing the wrong one
• Addition and subtraction constants stay under 50; multiplication and division facts stay to 13, so every answer is a positive whole number with no remainder and no negative sign
• The addition/subtraction bank and the multiplication/division bank are each deduplicated against the underlying arithmetic fact, so an equation and its algebraic rearrangement (like x+5=21 and a matching reverse equation) never both appear
• Sixty different equations across the six forms, none repeated
• Every form is a student sheet and nothing else: a big My name line, a small date line, one short instruction with a pencil picture, the ten problems numbered with room to work in every box, and one small gray tag naming the skill and the form letter. No goal text, no scoring strip, no directions: nothing on the page is written for an adult
• Rounded sans-serif type throughout, large, with white space (built to the store's student page standard)

The Answer Key And Scoring (Two Teacher Pages, 16 And 17)

• Every answer for all six forms, generated by the same code that draws the problems, in a numbered table that matches the numbers on the student sheet
• Under each form's answers, a row of boxes to mark each item and a Correct ___ / 10 box, so the scoring strip that used to sit on the form is here instead
• The giving-the-probe directions from the goal page, repeated on both pages, with the scoring rules: untimed, self-corrections count as correct, log the score the same day

The Data Log And Graph

• A y-axis already scaled 0 to 10, twelve probe columns, and the instruction to draw the aim line from the baseline to the criterion first
• A twelve-row log: date, form, correct, errors, the score used on the graph, and notes

The Caseload Summary

• Twelve student rows, baseline and criterion, eight probe columns, a trend column and a decision column
• For the data meeting: rows that are flat together are a group, a row that is flat alone is a different question

A Worked Example

• Marcus, seventh grade, invented. Twelve weekly probes: the baseline taken as a median, the aim line, three points under it forcing a teaching change (circled the operation sign and wrote its inverse above the equal sign before solving, on a week of equation warm-ups), the criterion met, and the progress-report sentence the log produces. Every number in that sentence is on the log.

A Family Update And Team Handoff Page

• A family update with blanks for this week's score and how it compares to the goal, ready to send home or read at a conference
• A team handoff checklist for a substitute, a new provider or a shift change, so whoever gives the probe that week knows exactly what to do
• A meeting summary sentence with blanks for the two numbers off the log, ready to drop into the progress report

What This Is, And What It Is Not

It is a fillable PDF. The goal page, the data log, the caseload page, the name and date lines on every student sheet, and the mark boxes and Correct box on the answer key are type-in fields: open the file in a PDF reader, click a line or a cell, type, and Save As once per student. The probe forms are meant to be printed: one copy per student per week, the student writes on the form, and that same sheet is the one you score. It works offline with no account or subscription. It does not calculate percents or draw the graph.

It is not a norm-referenced assessment and it carries no benchmark score or "typical" rate. The criteria in the sample goal are in brackets because your team sets them from the baseline and the student's IEP. Every probe is untimed on purpose; the goal page says so, so the condition stays the same all year.

Who This Is For

Sixth and seventh grade special education teachers and case managers writing one-step-equation computation goals, intervention and math resource teachers, and the paraprofessionals who give the weekly probe.
