THIS RESOURCE INCLUDES

#### Learning Resources

Lesson Plans:
First, follow these lesson plans or use the ideas to supplement your curriculum. There are 5 weeks or 25 lesson plan ideas.

In addition, use these posters as specified throughout the unit to help learners visualize the concepts taught. Posters include addition and subtraction definition, strategies and ways to add and subtract and addition and subtraction vocabulary.

Vocabulary Cards:
Also, post these cards on the math wall during the unit to refer to as new words are introduced.

#### Lesson Plans

First, have learners complete this book in a math center or as seat work.

Interactive Notebook:
With this lesson, have learners complete the addition and subtraction interaction notebook pages as a math rotation. Skills are reviewed throughout the unit in groups or partners.

In week one, focus on addition to ten through storytelling, read alouds, charts, manipulatives and more in a group, partners and independent learning settings.

In week two, continue using addition to twelve. Learners will become more familiar with the concept through the use of different addition strategies. Addition equations or number sentences are reviewed.

Subtraction from 10
In week three, focus on taking away through storytelling, read alouds, charts, manipulatives and more in a group, partners, and independent learning setting.

Subtraction from 10
In addition, week four continues using subtraction from twelve. Learners will become more familiar with the concept through the use of different subtraction strategies. Subtraction equations or number sentences will be reviewed.

Last of all, week five helps learners to understand which operation should be used. Through storytelling, word problems, class activities, your students understand addition and subtraction vocabulary and practice addition and subtraction problems.

#### Learning Centers

In this center, have learners use the pictures on the clip cards to clip the correct total of objects.

Monster Sets
With this activity, have learners match the monster pictures to the correct addition equation.

In this unit, have learners choose two cookie pictures and place them on the mat. Learners may then use a dry erase markers to solve the addition equation.

Gumball Ten Frame
In this center, have learners roll the dice to create an addition problem. Learners may use the mat and gumball manipulatives or pompoms to solve the equation.

Duck Away Equations
With this activity, have learners sort the duck equations on the mats according to the solution or difference each equation. Three ducks belong to each solution mat.

#### More Learning Centers

Subtraction Clip Cards
Next, have learners clip the correct equation for each of the pictures on the clip cards.

Gumball Subtraction Mats
In this center, have learners choose a number from a bag or bin and write the number on their subtraction mat. Learners subtract that number from twelve and use the mat or manipulatives to solve the equation.

S’mores Subtraction
In this activity, have learners match the correct difference to each of the equations.

In addition, have learners find the cards around the room. Learners may write and solve the equations as they find the cards.

Baseball Operation Sort
Last of all, have learners sort the baseballs by their operation (addition or subtraction). Learners may then solve each equation on the printable

## LEARNING STANDARDS INCLUDED IN THIS RESOURCE

### Common Core State Standards

#### Mathematics

CCSSK.NBT.A.1
Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
CCSSK.OA.A.1
Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
CCSSK.OA.A.2
Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
CCSSK.OA.A.3
Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
CCSSK.OA.A.4
For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
CCSSK.OA.A.5
Fluently add and subtract within 5.

### Texas Essential Knowledge and Skills

#### Mathematics

TEKSMA.K.2.I
Number and operations. The student applies mathematical process standards to understand how to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system. For example, the student is expected to: compose and decompose numbers up to 10 with objects and pictures.
TEKSMA.K.3.A
Number and operations. The student applies mathematical process standards to develop an understanding of addition and subtraction situations in order to solve problems. For example, the student is expected to: model the action of joining to represent addition and the action of separating to represent subtraction.
TEKSMA.K.3.B
Number and operations. The student applies mathematical process standards to develop an understanding of addition and subtraction situations in order to solve problems. For example, the student is expected to: solve word problems using objects and drawings to find sums up to 10 and differences within 10.
TEKSMA.K.3.C
Number and operations. The student applies mathematical process standards to develop an understanding of addition and subtraction situations in order to solve problems. For example, the student is expected to: explain the strategies used to solve problems involving adding and subtracting within 10 using spoken words, concrete and pictorial models, and number sentences.
