What addition & subtraction involves
- Recalling addition and subtraction facts accurately and quickly
- Using strategies such as counting on or making ten for unknown facts
- Adding and subtracting multi-digit numbers with and without regrouping
- Finding unknown numbers in equations
- Applying the operations in general computation probes
Baseline and measurement considerations
- Fact fluency is usually measured as digits correct per minute on short timed probes; use the median of three probes for baseline.
- Multi-digit computation fits percent accuracy on a fixed item set, with errors sorted by type.
- When the procedure breaks down at a specific step, a task-analysis checklist shows where.
- Keep probe length, format, and scoring rules the same each time so data points can be compared.
Progress-monitoring methods used in these templates
- Curriculum-based measurement: Brief, standardized probes given at regular intervals and scored the same way each time.
- Opportunity (trial) recording: Each planned or naturally occurring opportunity is recorded as correct/independent, prompted, or not demonstrated.
- Work-sample analysis: Scoring completed student work (permanent products) against a defined answer key or checklist.
- Task-analysis checklist: A routine is broken into ordered steps; each step is recorded as independent, supported, or not completed.
Matching data sheets
Each template links to a blank sheet built for its measure. You can also download these sheets on their own:
- Frequency & rate tracker: Counts a defined behavior during a fixed observation period. Calculates rate when time is recorded.
- Opportunity tracker: Records each opportunity as independent, prompted, or not demonstrated.
- Accuracy tracker: Number correct out of number attempted, with percent accuracy and support level.
- Task-analysis checklist: Marks each step of a routine as independent, with support, or not completed across sessions.
Common mistakes when writing addition & subtraction goals
- Setting a fluency goal for a student whose accuracy is still low; build accuracy or strategies first.
- Writing "with 80% accuracy" without saying what problems or how many.
- Mixing regrouping and non-regrouping problems in a goal meant to target regrouping.
- Changing probe length or problem types mid-year, which makes trend data unusable.
Frequently asked questions
What is "digits correct per minute"?
Each correct digit in an answer earns credit, so a partly correct two-digit answer still counts some digits. The total is divided by the minutes of the probe. It gives a more sensitive picture of growth than counting whole problems.
Should the goal allow a number line or counters?
If the student needs them to solve problems accurately now, include them as a defined support. Many teams fade concrete supports in short-term objectives as the student moves toward mental strategies.
How many problems should be in the item set?
Enough to make each item a reasonable share of the score; 10 problems is common for a skill-specific set. Fewer items make each error swing the percentage widely.
Do I need short-term objectives for a math goal?
Federal rules require benchmarks or short-term objectives for students who take alternate assessments aligned to alternate academic achievement standards (34 CFR §300.320(a)(2)(ii)). Some states and districts require them for more students, so check local policy. Where they are used, a skill progression (for example, easier number ranges first) is a practical way to write them.
