Add Bookmark
Description: In this lesson, one of a multipart 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. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Who's in the Fact Family?
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students explore the relation of addition to subtraction. Students use problemsolving skills to find fact families, including those in which one addend is zero or in which the addends are alike. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2

Subject: Mathematics Title: Exploring Adding with Sets
Add Bookmark
Description: This lesson, one of a multipart 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. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Counting Back and Counting On
Add Bookmark
Description: This lesson, one of a multipart 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. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: How Many More?

Description: In this lesson, one of a multipart unit from Illuminations, students write subtraction problems, model them with sets of fishshaped 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. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
