Decomposing Fractions Probes

About this resource

One skill, start to finish. A decomposing fractions IEP goal, four one-minute probe forms that measure it, answer keys, and a graph scaled to the probe. Baseline on Monday, goal written by Tuesday, first data point on Friday.

Every item asks the student to write a fraction as a sum of parts that share its bottom number: 5/6 as 1/6 + 1/6 + 1/6 + 1/6 + 1/6, or 3/4 as 2/4 + 1/4. Forms A and B are unit fractions with one answer per item. Forms C and D use two parts. Form D also includes two improper fractions, 7/4 and 3/2. No fraction repeats within a form.

WHAT IS INCLUDED - 19 pages, four one-minute probe forms of ten items each (40 items), 407 type-in fields, two answer-key pages, a Start Here page, a teacher notes page, a prompt bank, a binder cover with seven divider tabs, a family update and team handoff page, and a filled-in example with an invented student.

Start Here (Page 3)

• Five steps, and a table that says which page does which job

A Binder Cover And Seven Divider Tabs (Page 4)

• A binder cover with student, case manager, school year and goal date fields
• Seven divider tabs, one per section of this file, print and cut

The Goal Page (Page 5)

• Blank lines for the district's own IEP goal, and 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 with the median of three probes, three benchmark rows, and the timing and scoring directions

A Student Anchor Page (Page 6)

• Write a fraction as a sum: 3/4 written two ways, three steps, a Remember box, and two try-it rows

Four One-Minute Probe Forms, A Through D (Pages 7-10)

• Ten items per form, each with a blank for every part, printed with its bottom number
• A big My name line, one short instruction with a pencil picture, and a star to color when finished
• No answers, goal text or scoring strip on a student sheet

Two Answer-Key Pages (Pages 11-12)

• Every answer for all four forms, with a Right? box for each item and a Correct ___ / 10 box under each form

Teacher Notes And A Prompt Bank (Pages 13-14)

• Reading the errors: copying the whole fraction, changing the bottom number, too few parts, adding the bottoms, and stopping at a whole
• What to say when the student stops, the words to use when you teach it, and progress-note starters with blanks

A Data Log And Graph (Page 15)

• A y-axis scaled 0 to 10, twelve probe columns, the instruction to draw the aim line from the baseline to the criterion first
• A 13-row log with date, form, correct, errors and notes

A Caseload Summary (Page 16)

• Ten student rows, baseline and criterion, eight probe columns, a trend column and a decision column

A Filled-In Example (Page 17)

• Ava, fourth grade, invented: three baseline days, ten weekly probes, the aim line, the change that three low points forced, the criterion met, and the progress-report sentence the log produces

A Family Update And Team Handoff (Page 18)

• A family note with blanks for this week's score, a team handoff checklist, and a meeting summary sentence with blanks for the numbers off the log

What This Is, And What It Is Not

It is a fillable PDF. The goal page, data log, caseload page, family update page, and the Right? and Correct boxes on the answer keys 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 print clean: the student writes on paper.

It is not a norm-referenced test and it carries no benchmark score or "typical" rate. It measures one skill against a goal your team writes. The district's own rules for goals and scoring go on the blank lines provided. Forms A to D are one minute each; on Forms C and D any split that adds to the fraction counts. It is not a Google Slides, Docs or PowerPoint file.

Who This Is For

Grade 4 special education teachers and case managers writing fraction goals, intervention teachers, and the paraprofessionals who give the weekly probe.
