Course Plan: Addition Strategies within 20
Course Introduction
Welcome to the "Addition Strategies within 20" course! This engaging and interactive course is designed for 2nd-grade students to build a strong foundation in addition strategies that will help them confidently solve problems and enhance their mathematical thinking. Throughout this five-lesson course, students will explore various strategies for adding numbers up to 20, using visual aids, games, and hands-on activities to make learning fun and effective. By the end of the course, students will be equipped with a variety of tools to solve addition problems and improve their overall numeracy skills.
Lesson 1: Understanding Addition Concepts
Objectives:
- Introduce the concept of addition.
- Understand addition as combining groups of objects.
Activities:
- Warm-Up: Interactive discussion about addition in daily life (e.g., combining fruits).
- Direct Instruction: Use counting objects (blocks, counters) to visually demonstrate addition.
- Hands-On Activity: Group students to create their own addition stories with objects.
Assessment:
- Students will demonstrate basic addition through their stories and object grouping.
Lesson 2: Using Number Lines for Addition
Objectives:
- Learn to use a number line as a tool for addition.
Activities:
- Warm-Up: Review numbers on a number line.
- Direct Instruction: Show how to add numbers using jumps on a number line (e.g., 3 + 4).
- Interactive Game: Number line hopscotch, where students jump to find sums.
Assessment:
- Students will solve simple addition problems on a number line and share them with the class.
Lesson 3: Making Ten
Objectives:
- Discover how making ten can simplify adding larger numbers.
Activities:
- Warm-Up: Quick review of addition facts to 10.
- Direct Instruction: Explain how to break apart numbers to make a ten (e.g., 8 + 5 = 8 + 2 + 3).
- Hands-On Activity: Use ten frames to visualize making ten with different number combinations.
Assessment:
- Students will create their own addition problems using the making ten strategy and illustrate them with ten frames.
Lesson 4: Using Doubles to Add
Objectives:
- Learn the doubles strategy for addition (e.g., 2 + 2, 3 + 3).
Activities:
- Warm-Up: Review basic doubles facts.
- Direct Instruction: Explain how knowing doubles can help with near-doubles (e.g., 2 + 3 is 1 more than 2 + 2).
- Interactive Game: "Doubles Bingo," where students cover squares corresponding to doubles and near-doubles.
Assessment:
- Students will write and solve a set of addition problems using the doubles strategy and share with a partner.
Lesson 5: Solving Word Problems with Addition
Objectives:
- Apply learned addition strategies to solve real-world word problems.
Activities:
- Warm-Up: Review strategies learned in previous lessons.
- Direct Instruction: Introduce common word problem structures (e.g., "How many...," "If I have...").
- Group Activity: In small groups, students will create their own word problems and solve them using addition strategies.
Assessment:
- Each student will individually solve a word problem and explain the strategy they used to arrive at the answer.
Course Conclusion
By the end of this course, students will have a solid understanding of addition strategies within 20, including the use of number lines, making ten, doubles, and solving word problems. These foundational skills will prepare them for more complex mathematical concepts in the future and encourage a love for learning mathematics!
