**Title:** Fishy Addition!

**Description:**
In this lesson, students will use manipulatives to act out and solve simple addition problems.
**Standard(s): **

[MA2015] (0) 16: Classify objects into given categories; count the number of objects in each category, and sort the categories by count. (Limit category counts to be less than or equal to 10.) [K-MD3]

**Subject:**Mathematics (K)

**Title:** Counting Back and Counting On

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students model subtraction with connecting cubes while the teacher reads to them from counting books. Then, students make a train of connecting cubes and write in vertical and horizontal format the differences suggested by adding to and subtracting from the train, one cube at a time. Finally, students record in their learning portfolio for the unit a train showing one cube being taken away and record the difference in vertical and horizontal format. Several pieces of literature appropriate for use with this lesson are suggested.
**Standard(s): **

[MA2015] (1) 18: Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another. [1-MD4]

**Title:** Who's in the Fact Family?

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students explore the relation of addition to subtraction. Students use problem-solving skills to find fact families, including those in which one addend is zero or in which the addends are alike.
**Standard(s): **

[MA2015] (1) 8: Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. [1-OA8]

**Title:** Exploring Adding with Sets

**Description:**
This lesson, one of a multi-part unit from Illuminations, builds on previous lessons and encourages students to explore another model for addition, the familiar set model. Reading The Hershey s Kisses Addition Book sets the stage for this lesson in which students write story problems, find sums using sets, and present results in the form of a table. In the discussion of the table, the students focus on the order property and the effects of adding 0.
**Standard(s): **

[MA2015] (0) 13: 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.

**Title:** Counting Back and Counting On

**Description:**
This lesson, one of a multi-part unit from Illuminations, focuses on the counting model for subtraction. Students model numbers as a counting book is read. They then make a chain of links and write in vertical and horizontal format the differences suggested by adding and subtracting one link at a time from their chains. Finally, they draw a chain showing one link being taken away and write in two formats the difference it represents.

**Title:** How Many More?

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students write subtraction problems, model them with sets of fish-shaped crackers, and communicate their findings in words and pictures. They record differences in words and symbols. The additive identity is reviewed in the context of comparing equal sets. Several pieces of literature appropriate for use with this lesson are suggested.
