Unit Plan 36 (PreK Math): Cumulative Synthesis & Exhibition
Celebrate “Math All Around Us” as children count, sort, compare, build shapes, and act out add/take-away stories, then present their thinking with models, labels, and clear math language.
Focus: Celebrate “Math All Around Us” with integrated counting, shapes, sorting, measurement words, and add/take-away stories; students present and explain their work.
Grade Level: PreK
Subject Area: Mathematics (Comprehensive Spiral)
Total Unit Duration: 5 sessions (one week), 25–35 minutes per session
I. Introduction
This capstone week blends the year’s core ideas—counting and saying how many, comparing and sorting, building and naming shapes, position words, and joining/taking away stories—into joyful, authentic tasks. Children prepare a mini-exhibition to share models, language, and math thinking with classmates.
Essential Questions
- Where do we notice math in our classroom, outdoors, and in stories?
- How can models (ten-frames, blocks, pictures) help us explain our ideas clearly?
- What words show our math thinking (shape names, position words, more/fewer, how many)?
II. Objectives and Standards
Learning Objectives — Students will be able to:
- Count sets (arranged to 10; scattered to 5) and tell how many with confidence.
- Act out and explain simple join/take-away stories within 5 using objects or fingers.
- Sort items into categories and compare groups using more/fewer/same.
- Identify, build, and describe common 2D/3D shapes and use position words accurately.
- Share their work in a short presentation using models, labels, and clear math language.
Standards Alignment — Custom CCSS-style Pre-Kindergarten
- PK.CC — Counting & Cardinality (count to 10; one-to-one; cardinality).
- PK.OA — Operations & Algebraic Thinking (represent join/take-away within 5; decompose/make 5).
- PK.NBT — Number & Operations in Base Ten (experiences with ten as a bundle; teen = ten and some ones).
- PK.MD — Measurement & Data (describe/compare attributes; sort & talk about data).
- PK.G — Geometry (name/compare shapes; position words; build/compose shapes).
- Mathematical Practices: MP.1–MP.6 threaded (perseverance, reasoning, modeling, tools, precision, explanation).
Success Criteria — Student Language
- I can count and tell how many using my finger to touch each object.
- I can show a join or take-away story within 5 with objects or fingers and tell the result.
- I can sort and say which group has more/fewer/same.
- I can name and build shapes and use in/on/under/next to/behind/in front of.
- I can present my work with models, labels, and a clear sentence.
