Points, Lines, Rays, and Angles Progress Monitoring Probes

About this resource

One skill, start to finish. A figure-naming IEP goal, 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.

WHAT IS INCLUDED - 18 pages, six probe forms, 367 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 drawn figures per form: two each of a point, a line, a line segment, a ray, and an angle, every form
• A line is drawn with an arrowhead on both ends; a segment is drawn with a dot at each of its two endpoints and no arrows; a ray is drawn with one dot and one arrowhead — the arrows and dots are what the student has to read, never a hand-typed label
• Every drawn angle opens between 25 and 155 degrees, so it is never confusable by sight with a straight line or a single ray
• Every figure is labeled with letters, the way a textbook figure is labeled
• The direction (or, for the point, the letter) a figure is drawn with never repeats for that same figure type across the six forms — twelve different orientations for lines, twelve for segments, twelve for rays, twelve different openings for angles, and twelve different letters for the point
• 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

• Diego, third grade, invented. Twelve weekly probes: the baseline taken as a median, the aim line, three points under it forcing a teaching change (sorted a set of labeled figure cards into five piles (point, line, segment, ray, angle) for five minutes before each probe, checking each card for arrows, dots, or a bend before placing it), 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

Third and fourth grade special education teachers and case managers writing basic geometry goals for any age student, intervention and math resource teachers, and the paraprofessionals who give the weekly probe.

What'S Next

Once a student can name a point, line, line segment, ray, and angle, the next goal most teams write is classifying an angle by its degree measure — see this store's Classifying Angles Progress Monitoring Probes. Both are part of the Geometry and Measurement Progress Monitoring Probes Bundle, which also covers classifying 2D shapes, 3D shape attributes, and measurement/volume conversion, at a bundle discount over buying each one alone.
