Title: Number Carousel
Description: First grade students will be able to use various strategies and their understanding of addition to make 10 and 17 in multiple ways. Lesson will help students use 2 or 3 different numbers to make 10 or use 2 or 3 different numbers to create numbers up to 20. This is a College- and Career-Ready Standards showcase lesson plan.

Title: Camp Add 'Em Up III
Description: Camp Add 'Em Up is a series of lessons for first grade students. Students will use prior knowledge of friendly numbers (two number combinations that make a "10") and "adding on" as they master the ability to add three numbers. In this lesson, students will use manipulatives as they explore adding numbers to make sums up to 20. The Hundreds chart handout used in this lesson has English and Spanish number words which will accommodate students who wish to explore a second language or to aid Spanish ELL students.

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.

Title: Fact Families
Description: In this lesson, one of a multi-part unit from Illuminations, students use books and connecting cubes to explore the relationship of addition to subtraction. Students search for related addition and subtraction facts for a given number using a virtual or actual calculator to find differences. They also investigate fact families when one addend is 0 as well as when the addends are the same. Several pieces of literature appropriate for use with this lesson are suggested.

Title: Calculating Patterns
Description: In this lesson, one of a multi-part unit from Illuminations, students use an Internet-based calculator that is linked with an interactive Hundred Chart to create, extend, and record numerical patterns in different ways. By connecting the two representations, students observe the numerical patterns as they are created.

Title: Lost Buttons
Description: In this lesson, one of a multi-part unit from Illuminations, students investigate subtraction more directly, beginning with the easier take away mode. They model take away subtraction with buttons and write subtraction sentences. They also work with the additive identity (0) as an addend and as a difference and find missing addends.

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.

Title: Investigating Greater Than, Less Than, and Equal To
Description: Students are introduced to the concepts of greater than, less than, and equal to by observing quantities and making comparisons. Using varied instructional materials such as play dough, buttons, beans, and cotton balls, students will create amounts to compare with the use of a double-sided fish. Depending on its position, the fish cut-out (with its mouth open) can represent either greater than or less than. For equivalent amounts, a clam cut-out can represent equal to.

Title: Combining Foods
Description: In this lesson, one of a multi-part unit from Illuminations, students explore addition and comparison subtraction by modeling and recording related addition and subtraction facts for a given number. The students also investigate the commutative property and model fact families, including those in which one addend is zero and those in which the addends are alike.

Title: Block Pounds
Description: In this lesson, from Illuminations, students explore the use of variables as unknowns as they solve for the weights of objects using information presented in pictures. They also model situations that involve the addition and subtraction of whole numbers, using objects, pictures, and symbols.
