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.

12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

[2MD5] [MA2013] (3) 4: Determine the unknown whole number in a multiplication or division equation relating three whole numbers. [3OA4] [MA2013] (4) 6: Recognize that in a multidigit whole number, a digit in one place represents ten times what it represents in the place to its right. [4NBT1]

Subject: Language Arts,Mathematics Title: Lost Buttons
Description: In this lesson, one of a multipart 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: Calculating Patterns
Description:
In this lesson, one of a multipart unit from Illuminations, students use an Internetbased 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.

Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows
12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13). [1OA6]

Title: Fact Families
Description:
In this lesson, one of a multipart 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.
