Description: In this lesson, one of a multipart unit from Illuminations, students explore the many ways to decompose numbers and then build on their knowledge of addition and subtraction to find missing addends. They also visit a Web site related to the food pyramid. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Hopping on the Number Line
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students generate sums using the '' number line'' model. This model highlights the measurement aspect of addition and is a distinctly different representation of the operation from the model presented in lesson one. The order property is also introduced. At the end of the lesson, students are encouraged to predict sums and to answer puzzles involving addition. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2

Subject: Language Arts,Mathematics Title: Comparing Sets
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, a children s book sets the stage for encouraging students to review counting back. Students write subtraction problems and model them with cubes. They then compare sets and record differences in the form of a table. The additive identity is reviewed in the context of comparing equal sets. Several pieces of literature appropriate for use with this lesson are suggested.

Subject: Mathematics Title: Do It With Dominoes
Add Bookmark
Description: In this sixlesson unit from Illuminations, students explore the four models of addition (counting, sets, number line, and balanced equations) using dominoes. Students also learn about the order property, the relation between addition and subtraction, and the result of adding 0. Students engage in a variety of activities, including writing story problems in which the operation of addition is required, beginning to memorize addition facts, investigating properties of addition, and representing addition in pictures.

Subject: Mathematics Title: Building Sets of 13 and 14
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students explore sets of 13 and 14. They construct and identify sets of size 13 and size 14. They then compare sets to sets of size 13 and size 14, record the number in the sets, and decompose a set of 13 and a set of 14 in several ways.
