Estimate how many objects are in a group
When to use this goal
For students whose guesses about quantity are far off ("a hundred" for a jar of 15) or who refuse to estimate without counting. Present levels in counting and in benchmark sets (knowing what 10 looks like) decide the sizes used.
- Baseline
- Decide the tolerance before baseline (for example, within 25% of the actual count, or within 5 for sets under 20) and keep it fixed. Record the estimate and the actual count so the pattern (always too high, always too low) is visible.
- Tips
- Make estimating safe: there is no single right answer, only a reasonable range. Checking by counting after estimating builds the link between the two and keeps the activity honest.
- Limits
- Tolerance rules are a scoring convention; wider rules make the goal easier. Does not measure computational estimation (rounding); see the rounding template for that.

Goal
By the annual IEP review date, given a jar or picture of 10 to 50 objects and a reference set of 10 of the same objects, the student will state an estimate and then count to check it independently in at least 4 of 5 opportunities, across 3 consecutive data collection sessions, as measured by opportunity-by-opportunity data collected weekly.
Baseline: 1 of 5 opportunities.

Met: Observable behavior. Stated as an action.

Met: Unit fits the behavior. Opportunities fits this behavior.
Met: Explicit criterion. Number and unit stated.
Met: Mastery rule and schedule. Both stated.
Met: Method produces the metric. Opportunity (trial) recording gives opportunities data.
Met: Review timeframe. Stated.
Met: Baseline and target compatible. Same unit, change in the right direction.
Met: Aligned with area of need. Still about Number Sense.
Met: Level of support. Defined.
Met: Blanks filled in. Nothing left to fill in.
Checks structure and wording only. Whether the goal fits the student is the team's call.
Short-term objectives (optional)
When are objectives required?Required for students on alternate assessments (34 CFR §300.320(a)(2)(ii)); some states require them for everyone.

- Record up to 5 opportunities per session, matching the goal's denominator.
- Define in advance what counts as an opportunity so every data collector records the same thing.
- Count only + marks toward the criterion unless the goal specifies prompted responses.
