**Lesson Plan: Number Operations in Base Ten**
**Grade Level:** Kindergarten
**Subject:** Mathematics
**Topic:** Number Operations in Base Ten
**Duration:** 45 minutes
---
### **Objective:**
- Students will understand and apply base ten number operations, specifically focusing on numbers 0-20.
- Students will be able to recognize and count numbers in base ten using manipulatives.
### **Materials Needed:**
- Base Ten Blocks (Unit cubes, Rods/Longs, Flats)
- Number cards (0-20)
- Interactive whiteboard or large chart paper
- Markers
- Worksheets with simple base ten problems
- Small whiteboards and markers for students
- Small bags for manipulatives
### **Standards:**
- Common Core State Standards (CCSS.MATH.CONTENT.K.NBT.A.1): Compose and decompose numbers from 11 to 19 into ten ones and some further ones.
---
### **Introduction (10 minutes):**
1. **Greeting and Warm-Up:**
- Welcome the students and discuss the importance of numbers in everyday life.
- Organize a quick counting activity: go around the room counting from 1 to 20 together.
2. **Introduction to Base Ten:**
- Show students base ten blocks and explain that these blocks help us see numbers in groups of ten and ones.
- Demonstrate with manipulatives: show a single unit (one block) and explain it represents the number one. Show ten units creating a rod/long, representing the number ten.
### **Direct Instruction (15 minutes):**
1. **Demonstration:**
- Use the interactive whiteboard or chart paper to show how to build numbers using base ten blocks.
- Show the number 12 using one rod (10) and two units (1+1). Explain: "This is how we make 12; one group of ten and two ones."
2. **Interactive Activity:**
- Call up a few students to come to the board and build different numbers between 10-20 using the base ten blocks.
### **Guided Practice (10 minutes):**
1. **Hands-On Activity:**
- Give each student or small group a bag of base ten blocks and a set of number cards (0-20).
- Have students pick a number card and build that number using their blocks.
- Walk around, check for understanding, and provide guidance as needed.
2. **Numbers 11-20 Focus:**
- Emphasize composing numbers from 11 to 19 by physically showing ten blocks and additional units.
- For example, for the number 14, show one rod and four units.
### **Independent Practice (5 minutes):**
- Distribute worksheets with base ten problems. Problems should include pictures of rods and units, asking students to identify the number represented or draw the corresponding number.
### **Closing (5 minutes):**
1. **Review:**
- Quickly review what was learned today. Ask students: "How do we make the number 15 using base ten blocks?"
- Allow a few students to demonstrate their answers with manipulatives.
2. **Wrap-Up:**
- Praise the students for their effort and participation.
- Remind them that they can practice this at home using everyday objects (e.g., group ten sticks or straws to practice making numbers).
### **Homework/Extension:**
- Send home a simple practice sheet for students to extend their learning.
- Encourage parents to play a counting game with their child using objects around the house (buttons, coins, etc.), grouping them into tens and ones.
---
**Assessment:**
- Observe students during guided practice for understanding and correct manipulation of base ten blocks.
- Review the independent practice worksheets for accuracy.
- Conduct informal one-on-one or small group check-ins as needed.
