Geometry, Counting, & Spatial Reasoning
A Weeklong Summer Camp for 3rd - 5th graders
Based on the “Geometry and Spatial Sense” course I developed
while teaching for the Center for Talented Youth (CTY)
COW HOLLOW, SAN FRANCISCO
JUNE 15-19, 2026
9am - 3pm
OUTER RICHMOND, SAN FRANCISCO
JULY 27-31, 2026
9am - 3pm
Who
3rd - 5th* graders who enjoy math and wish to understand math more deeply and experience greater challenge. (We are open to strong 2nd graders too!)
Goals
Reinforce key geometry and counting content, and expose them to deeper geometry and counting problems than they experience in school
Develop an understanding of why math works and how concepts are connected, often in surprising ways
Develop strong problem-solving and logic skills, which can be applied to any future learning
Satisfy students via extensions & challenge topics based on my years of experience developing deep curriculum for elementary and middle school students for the Center for Talented Youth (Johns Hopkins), Bridge to Enter Advanced math (AoPS) and the San Francisco Math Circle
Develop teamwork and communication skills by discussing and presenting their work
Topics
Topics include a combination of standard geometry concepts commonly taught in middle and high school, and a multitude of extension problems that combine geometry, counting, and spatial reasoning. Most activities will be hands-on, involving coloring, compass & straightedge, rearranging objects, puzzles, games, etc. We will customize all programming to the group itself.
Congruence, Similarity, Reflections
Polyominoes: developing algorithms to count them, tiling puzzles, nets of cubes
Compass & straightedge constructions, including ancient method for approximating pi
Proofs of basic compass & straightedge constructions
2D Geometry: angles, perimeter, circumference
Which regular polygons tile the plane? And math art through creating tesselations
3D Geometry: Surface Area & Volume; Platonic solids
What is the 4th dimension?
Geometric origami
Map & Graph Coloring
Other notions of distance…
Math Yoga
& More
Daily Schedule
Fun warm up activity
More serious math session
Morning break
Continued math session
Longer mid-day break to include outdoor recess at nearby park
Afternoon math session
Reflections / sharing
We will invite parents to an end-of-week celebration on Friday afternoon!
Logistics
Week-long Math Camps in small cohorts of 8 students max.
Since we are expecting mixed-age groups, students will be split into subgroups based on grade / knowledge / ability. There are plenty of math challenges to go around!
