What geometry & spatial reasoning involves
- Matching, naming, describing and sorting two- and three-dimensional shapes
- Following and using positional words such as above, behind and between
- Composing shapes, drawing shapes and finding lines of symmetry
- Classifying angles, triangles and quadrilaterals by their properties
- Finding perimeter, area, volume, surface area and circumference
- Plotting points, performing transformations and using scale drawings
Baseline and measurement considerations
- Early shape goals are scored per opportunity; show shapes in different sizes, colors and orientations so the student responds to shape, not to a familiar picture.
- Receptive (point to) and expressive (name) responses are different skills; probe and score them separately before choosing which goes in the goal.
- For measuring with a protractor or ruler, decide the tolerance (nearest 5 degrees, nearest half inch) before baseline and keep it fixed.
- For formula-based goals, score the number and the unit separately, and state whether a formula card and calculator are allowed.
- Drawing shapes involves fine motor skill; if a student can build a shape but not draw it, a fine motor goal may be the better fit.
Progress-monitoring methods used in these templates
- 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.
- Direct observation: An adult observes and records the defined behavior during a specified activity.
How each measure works
- Opportunity (Trial) Data: Number of opportunities in which the behavior is demonstrated, out of a fixed number.
- Percent Accuracy: Percent of attempted items answered correctly.
Matching data sheets
Each template links to a blank sheet built for its measure. You can also download these sheets on their own:
- 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.
Common mistakes when writing geometry & spatial reasoning goals
- Writing "will identify shapes" without naming which shapes or whether the student points or names.
- Testing only regular, upright shapes, so a rotated triangle or a long thin hexagon reveals the student was matching pictures rather than counting sides.
- Mixing perimeter and area in one goal, so the data cannot show which concept is confused.
- Writing a protractor goal for a student whose vision or fine motor needs make the standard tool unusable, instead of naming an adapted tool.
- Using definitions (especially trapezoid) that differ from the classroom textbook, so the student is marked wrong in class and right on the probe.
