Unit Plan 36 (Grade K Math): Cumulative Synthesis & Exhibition
Showcase counting, comparing, operations to 10, teen numbers, shapes, and data through hands-on challenges and math talks, using clear evidence and multiple representations.
Focus: Show what you know: counting, comparing, operations to 10, teen numbers, shapes, and data; student math talks and showcases.
Grade Level: K
Subject Area: Mathematics (Comprehensive Spiral)
Total Unit Duration: 5 sessions (one week), 30–40 minutes per session
I. Introduction
This capstone week invites students to bring together the year’s big ideas—counting, comparison, adding/subtracting within 10, teen numbers as a ten and some ones, shape attributes, and sorting/data—in hands-on challenges and a simple exhibition. Emphasis is on clear evidence and student explanations (“show-and-tell” math talks).
Essential Questions
- How do I choose tools and representations to show evidence for my math ideas?
- What does it sound like to explain and justify my answer to a partner?
- How can different representations (objects, drawings, ten-frames, charts) show the same idea?
II. Objectives and Standards
Learning Objectives — Students will be able to:
- Count objects and write/read numerals in common classroom contexts.
- Compare sets and numbers using more/fewer/same and give a reason.
- Use addition/subtraction within 10 with objects, drawings, or equations.
- Represent teen numbers as a ten and some ones and explain.
- Identify/describe 2D/3D shapes and sort objects to make simple data displays.
- Present a solution with clear evidence, math vocabulary, and listening to feedback.
Standards Alignment — CCSS Kindergarten (spiral across the unit)
- K.CC: Count to answer “how many,” read/write numerals, compare numbers.
- K.OA: Represent and solve addition/subtraction problems within 10; decompose numbers; make ten.
- K.NBT.1: Compose/decompose 11–19 as ten and ones.
- K.MD: Describe/compare measurable attributes; sort and count categories.
- K.G: Name, describe, and model shapes; use position words as needed.
- Mathematical Practices (MP.1–MP.6) threaded: persistence, reasoning, modeling, tools, precision, structure.
Success Criteria — Student Language
- I can show and tell my math using tools and clear evidence.
- I can explain why my answer makes sense and revise after feedback.
- I can use math words like more, fewer, add, subtract, ten, ones, shape, sort, graph.
