Subject: Mathematics Title: Begin with Buttons: Looking Back and Moving Forward
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students review the work of the previous lessons through a variety of activity stations, one of which involves using an interactive Web site. Students model with buttons and record addition and subtraction. 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: Mathematics Title: Zero Our Hero
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students explore sets of zero items and practice writing the numbers 0 through 5. Students count back from five, identify sets of up to five items, and record 0 on a chart. They also construct sets of up to five items. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Let's Learn Those Facts: Looking Back and Moving Forward
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students display their knowledge of properties of objects for sorting and creating patterns. They also demonstrate an understanding of commutativity and model addition and subtraction of whole numbers using different representations. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Language Arts,Mathematics Title: Counting Back and Counting On
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: Building Numbers to Five
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students make groups of zero to five objects, connect number names to the groups, compose and decompose numbers, and use numerals to record the size of a group. Visual, auditory, and kinesthetic activities are used to help students begin to acquire a sense of number. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Links Away
Add Bookmark
Description: In this sevenlesson unit, from Illuminations, students explore the five models of subtraction (counting, sets, number line, balanced equations and inverse of addition) using links. They also learn that the order property does not hold for subtraction and explore the relation between addition and subtraction. Students also write story problems in which subtraction is required and begin to memorize the subtraction facts. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Block Pounds
Add Bookmark
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. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Finding Four
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students explore the number four. They make sets of four, write the numeral 4, and compare sets of four to sets of one, two, and three. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: How Many Under the Shell?
Add Bookmark
Description: This student interactive from Illuminations allows students to discover basic addition and subtraction facts. When Okta hides bubbles, students try to determine the number under the shell. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Fact Family Fun
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, the relation of addition to subtraction is explored with fishshaped crackers. The students search for related addition and subtraction facts for a given number and investigate fact families when one addend or the difference is 0. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
Subject: Mathematics Title: Five Frame
Add Bookmark
Description: This student interactive from Illuminations presents four games that help students develop counting and addition skills. Each of the games uses a frame of five. Thinkfinity Partner: Illuminations Grade Span: K,PreK,1,2
