 TITLE : Unit 05: Addition and Subtraction up to 20 SUGGESTED DURATION : 15 days

#### Unit Overview

Introduction
This unit bundles student expectations that address representing and solving addition and subtraction problem situations by applying basic fact strategies and properties of operations. According to the Texas Education Agency, mathematical process standards including application, a problem-solving model, tools and techniques, communication, representations, relationships, and justifications should be integrated (when applicable) with content knowledge and skills so that students are prepared to use mathematics in everyday life, society, and the workplace.

Prior to this Unit
In Unit 02, students represented and solved contextual or real-world problem situations involving sums and minuends up to 10 while exploring basic fact strategies and properties of operations.

During this Unit
Students extend representing and solving contextual or real-world problem situations involving sums and minuends up to 20 using spoken words, objects, pictorial models, and number sentences. They explore and explain a variety of strategies to solve problems involving action (joining and separating problems), and problems involving no action (part-part-whole and comparing problems). While demonstrating various strategies, students explore and apply properties of operations. While students are not expected to recognize properties by name, they are expected to be able to apply and explain the associative property of addition (if three or more addends are added, they can be grouped in any order, and the sum will remain the same), the commutative property of addition, (if the order of the addends are changed, the sum will remain the same), and additive identity (the sum/difference is not affected when zero is added/subtracted to a number). Students are expected to use a number sentence to represent the problem and explain that the equal sign represents a relationship where expressions on each side of the equal sign represent the same value(s). Through the continued use of experiences with addition and subtraction situations, students begin to recognize basic fact relationships, which are essential for developing computational fluency. They also apply composition and decomposition of numbers to determine the unknown whole number when the unknown may be any one of the three or four terms in the equation. Within this unit, students also experience generating addition and subtraction situations when given a number sentence involving addition or subtraction of numbers within 20. Thorough understanding of analyzing problems and using the problem-solving process in addition and subtraction situations involving sums and minuends up to 20 is critical in setting the foundation for students’ success in mathematics as they progress through future grade levels.

Research
According to Chapin (2000), “Students need to understand a variety of approaches to solving problems in order to choose the most appropriate method based on the numbers involved and the complexity of the procedure” (p. 39). The National Research Council (2001) states, “Students should begin their study of number situations by modeling problems directly, using the context to shape their concrete methods” (p. 217).

#### MISCONCEPTIONS / UNDERDEVELOPED CONCEPTS

Misconceptions:

• Some students may think they must add or subtract in the order that the numbers are presented in the problem rather than performing the operation based on the meaning and action(s) of the problem situation.
• Some students may think subtraction is commutative rather than recognizing the minuend as the total amount and the subtrahend as the amount being subtracted (e.g., 5 – 3 is not the same as 3 – 5, etc.).
• Some students may think the equal sign means that an operation must be performed on the numbers on one side and the result of this operation is recorded on the other side of the equal sign rather than understanding that operations and/or individual numbers can be on either side of the equal sign as long as they represent equal quantities.

Underdeveloped Concepts:

• Some students may not recognize the difference between an addition situation and a subtraction situation based on the context of the problem.
• Some students may confuse the –, +, and = symbols due to not fully understanding the meaning of each symbol.
• Some students may correctly determine related addition number sentences but have difficulty determining the subtraction number sentences within a fact family.
