Assessment Protocols Kindergarten Geometry Unit
Singapore Math CPA Alignment (Concrete • Pictorial • Abstract)
Kindergarten geometry relies heavily on oral language and physical handling before abstract pencil-and-paper mastery. Use the student booklet for pictorial assessment, and administer the oral check and hands-on station below to capture full developmental understanding.
1 1-on-1 Oral Assessment Protocol (2–3 Minutes Per Student)
Administer during independent work
| Skill Tested |
Teacher Script & Prompt |
Target Response & Look-Fors |
| Closed vs. Open |
Point to shape #1 (circle) and #2 (open curve): "Can a tiny bug walk inside this shape without crossing a line? Why is one closed and one open?" |
Identifies that the closed shape has a complete boundary with no gate or gap. |
| Curved vs. Flat |
Hand student a wooden sphere and a cylinder: "Does this ball have any flat faces? Can it slide? What about this can?" |
Articulates that sphere is only curved (rolls); cylinder has 2 flat faces (slides) and 1 curved side (rolls). |
| Squares & Rectangles |
Show a tilted square: "Some people say this is a diamond. Is it still a square? How do you know?" |
Confirms it is a square because it still has 4 straight equal sides and 4 square corners, regardless of orientation. |
| Spatial Positions |
Place a block under a chair: "Where is the block? Use math position words like above, below, or next to." |
Uses below / under accurately without guessing or pointing silently. |
2 Hands-On Station Tasks (Manipulatives Check)
Materials: Pattern blocks & 3D solid blocks
Station A
Shape Builder (Combine Shapes)
Give student green triangle pattern blocks and a yellow hexagon block.
Prompt: "How many green triangles do you need to completely cover the yellow hexagon?"
✓ Mastery Look-For: Uses 6 triangles with edges aligned, demonstrating shape composition.
Station B
Roll vs. Slide (3D Shapes)
Provide an incline ramp and foam solids (cube, sphere, cylinder, cone).
Prompt: "Test each solid on the ramp. Put shapes that ROLL here and shapes that SLIDE here."
✓ Mastery Look-For: Observes that flat faces slide and curved faces roll (cylinder & cone can do both!).
Kindergarten Anecdotal Tracking Grid
Vocabulary Side, corner, face, roll, slide, straight, curved
Position Words Above, below, beside, between, next to, under
Shape Constancy Identifies shapes regardless of size or rotation
Data & Graphing 1-to-1 correspondence when counting & filling cells

| Level |
Score |
Performance Descriptors & Observable Evidence |
| 4 - Exceeds / Advanced |
19–20 pts |
Independently identifies all 2D and 3D shapes, explains properties using precise math vocabulary (sides, corners, faces), decomposes complex figures with ease, and reads graph accurately. |
| 3 - Proficient / Meets |
16–18 pts |
Consistently recognizes shapes and solid figures. Distinguishes curved vs. flat and open vs. closed. Accurately applies spatial position terms and completes the picture graph with minor prompting. |
| 2 - Developing |
12–15 pts |
Confuses rectangles with squares when orientations change. May confuse 2D circles with 3D spheres or cylinders. Needs teacher assistance with 1-to-1 correspondence when graphing. |
| 1 - Beginning / Needs Support |
< 12 pts |
Struggles to differentiate straight sides from curved boundaries. Cannot reliably match 3D solids to real-world objects. Requires targeted concrete reteaching with physical manipulatives. |
Common Kindergarten Misconceptions & Concrete Interventions
Misconception: Orientation Bias
Students often think a square rotated by 45° is a "diamond" and no longer a square. Intervention: Physically rotate a square cutout in front of the student so they witness that turning a shape does not change its name or number of equal sides.
Misconception: 2D vs. 3D Confusion
Calling a cylinder a "circle" or a cube a "square". Intervention: Practice stamping. Show that the flat face of a cylinder stamps a 2D circle, but the solid itself can roll and has 3D volume.
