5-Probe Key

1

Devon's Game Points: 43 points + 35 points

43 + 35 = 78 78 points

2

Bakery Chocolate Cookies: 80 cookies - 47 sold

80 - 47 = 33 33 cookies

3

Art Class Colored Markers: 28 markers + 46 markers

28 + 46 = 74 74 markers

4

Parking Lot Cars: 93 cars - 58 drove away

93 - 58 = 35 35 cars

5

Sophia's Game Tokens: 64 tokens - 29 tokens

64 - 29 = 35 35 tokens

Accuracy Score Table (5 Items)

IEP Scoring Criteria:

• Strategy Criterion: Student must produce a visual representation, write a number equation, set up manipulatives, OR record calculator steps.
• Calculation Criterion: The numerical sum or difference must be exact. Minor unit label omissions do not negate calculation accuracy for this goal.
• Calculator Policy: Keying into a calculator is an approved goal strategy. Check that the student entered the correct operation sign (+ or -).

Tip: If the student calculated correctly using mental math but showed no strategy, prompt once: "Show or tell me how you solved it" before recording data.

Scoring Rules for the 80% Benchmark

• Probe Length: Each weekly probe consists of 5 items. 4 correct = 80%; 5 correct = 100%.
• Criterion Requirement: The student must demonstrate at least one problem-solving strategy (drawing, equation, manipulatives, or calculator). If only an answer is written without any evidence of strategy, prompt the student to show or explain their method.
• Reading Accommodation: Word problems may be read aloud to the student if designated in their IEP without invalidating math goal accuracy.

Common Errors & Quick Corrections

• Wrong Operation: Student adds when they should subtract. Correction: Prompt with Part-Part-Whole: "Do we already know the total, or are we finding the total?"
• Calculator Transposition: Student types 58 instead of 85. Correction: Have student read the calculator screen numbers aloud before pressing [=].
• Regrouping Confusion: In pencil calculations, student flips digits (e.g. 80 - 47 → 47 - 0). Correction: Route student to calculator or base-10 blocks.

Progress Monitoring Decision Tree

Score: 0% – 40% (0-2 Correct)

Action: Reduce number magnitude (within 50). Require physical base-ten blocks before moving to drawings. Pair with high-intensity 1-on-1 guided practice.

Score: 60% (3 Correct)

Action: Review key operational vocabulary. Encourage dual-strategy use (e.g., sketch bar model first, then calculate using calculator for verification).

Score: 80% – 100% (4-5 Correct)

Action: When achieved across 3 consecutive weekly probes, convene IEP team to mark goal mastered and propose two-step word problem goals.
