Transfer: 1. Makes sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning.

Established Goals:

K.OA.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

K.OA.2Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

K.OA.5Fluently add and subtract within 5.

Student "I Can" Statements:

I can use objects, fingers and pictures to help me show addition.

I can use objects, fingers and pictures to help me show subtraction.

I can solve addition and subtraction word problems within 10.

I can add and subtract within 5.

Prerequisite Standards:

N/A

Big Ideas:

Operation Meanings and Relationships There are multiple interpretations of additions, subtractions, multiplication, and division of rational numbers and each operation is related to other operations.

Practices, Processes, and Proficiencies Mathematics content and practices can be applied to solve problems.

Essential Questions:

How can numbers form 0 to 20 be counted, read, and written?

Students will know...

Joining parts to make a whole is one interpretation of addition.

Joining groups can be shown in an addition expression that uses the plus sign (+).

Addition number sentences using + and = can be used to show parts of a whole.

Information in a problem can often be shown using a picture of diagram and used to understand and solve the problem.

Vocabulary:

number story
join
in all
altogether
add
plus sign
addition sentence

Students will be skilled at...

Acting out number stories that involve joining two groups.

Interpreting illustrations that show joining groups and write the corresponding numbers.

Determining how many there are altogether when two groups are joined.

Using the plus sign (+) to represent joining groups when recording addition.

Identifying and using the equal sign (=); add and write the sum.

Writing and solving addition sentences to represent joining situations.

Solving problems by drawing pictures about joining two groups.
