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: Create a House Number: Grades 12
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students look for all the possible solution sets for a mathematics problem involving a threedigit house number. They experiment with numbers to find all possible ways to add three different digits to obtain the given sum of six and explore the ways three digits can be placed together to form different threedigit numbers.

Subject: Mathematics Title: Further Investigating Greater Than, Less Than, and Equal To
Add Bookmark
Description: Students build upon their understanding of greater than, less than, and equal to by observing quantity and making comparison using varied instructional materials. The fish cutout, with its mouth open, represents the greater than or less than symbol; the clam cutout represents the equal to symbol. Using fish lips as a transition point, children will apply their understanding of greater, less, and equal to the standard symbols as the teacher introduces symbolic notation at an developmentally appropriate level.

Subject: Mathematics Title: Building Sets of Ten
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students explore sets of up to 10 items and practice writing the numbers 0 through 10. Students count back from 10, identify sets of up to 10 objects, and record 10 on a chart. They also construct and decompose sets of up to 10 items. This lesson provides opportunities for reasoning and communication. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
