### Count Objects

K.CC.4 Understand the relationship between numbers and quantities; connect counting to cardinality.

K.CC.4.AK.CC.4.A When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.

K.CC.4.BK.CC.4.B Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.

K.CC.4.CK.CC.4.C Understand that each successive number name refers to a quantity that is one larger.

K.CC.5K.CC.5 Count to answer "how many?" questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.

This lesson focuses on counting to cardinality by counting objects. The lesson includes research-based strategies and strategic questions that prepare students for assessments. For this lesson, students will need to be able to write numbers 1-20 (K.CCA.3).

### Represent Addition

The goal of this lesson is rote memorization of the addition facts. As a result, this lesson is set up with Skill Development/Guided Practice pages, followed by Independent Practice for each number. Cumulative Periodic Review pages are at the end of the lesson. Flashcards are provided with this lesson.

### Memorize Subtraction Facts

This Operations and Algebraic Thinking lesson practices memorizing subtraction facts. The lesson includes research-based strategies and strategic questions that prepare students for assessments. The goal of this lesson is rote memorization of the subtraction facts. As a result, this lesson is set up with Skill Development/Guided Practice pages, followed by Independent Practice for each number. Cumulative Periodic Review pages are at the end of the lesson. Flashcards are provided with this lesson.

### Add Numbers

This number sense lesson focuses on adding numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the students read the addition problem, and then add the numbers counting from the first number. Finally, they write the answer and read the problem and answer out loud. In addition to the lesson, there are six pages of Independent Practice and review modeled on current adaptive testing items.

### Show the Meaning of Addition

This number sense lesson focuses on showing the meaning of adding. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students count and write the number of objects in each group, and put them together to show the meaning of adding. Then, they write the total amount and read the problem aloud. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.

### Subtract Numbers

This number sense lesson focuses on subtracting numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, the students read the subtraction problem and then subtract the numbers by taking away so many and counting the objects left. Finally, they write the answer and read the problem and answer out loud. In addition to the lesson, there are five pages of Independent Practice and review modeled on current adaptive testing items.

### Decompose Numbers 11 to 19
