This animated learning tool can be viewed on a projection screen, interactive whiteboard or Smart Board, or on a computer screen. Although the file is created with MS PowerPoint, the program is not needed to view the presentation. The PowerPoint Viewer is embedded in the file, and will allow the user to have full use of presentation capabilities.

Here's what's included:
28-Page Interactive PowerPoint Show (.ppsx)
Student Follow-Along Recording/Response Sheet that coordinates with the PowerPoint Show
2 Practice Worksheets or Homework Sheets to reinforce the concept
4 Generic Worksheet Frames, designed to be edited by teachers to match their own class’ needs
Common Core Alignment Document and link to professional reading concerning introducing algorithms
Illustrated Vocabulary Card for the term, ALGORITHM
Student "I Can" Statement Mini-Posters
Video-clip/Link to a short demo of how to use the PowerPoint Show

Description:
Catchy music captures students’ attention and on-screen kid-friendly dialogue keeps them engaged. Repetition of important concepts and models enhance the learning experience.

The relationship between the place value concept and the use of the algorithm is stressed throughout the practice session.

The PowerPoint and worksheets feature adorable artwork from Educlips, and bold, attractive, kid-friendly fonts from KG Fonts.

This PowerPoint lays a good foundation for the introduction to the concept of mathematical algorithms. Clear and simple definitions are featured onscreen in a fun way. The teacher has wide latitude to enhance the information to fit the needs of his/her students.

Visual examples of Base Ten Models illustrate the subtraction scenarios. The Student Response Sheet prompts and scaffolds the students in the process of writing the algorithm and drawing Base Ten Models to illustrate the presented problems. Audio cues help to ensure engagement and participation.

If the teacher wishes, actual Base Ten Pieces (tens and ones) can be used at each student's desk or work space in lieu of having students draw the Base Ten models.

Catchy music captures students’ attention and on-screen kid-friendly dialogue keeps them engaged. Repetition of important concepts and models enhance the learning experience. The PowerPoint and worksheets feature adorable artwork from Educlips, and attractive kid-friendly fonts from KG Fonts.

Teachers might find this activity to be of value for use with a differentiated group. A parent or instructional assistant could easily lead this activity. Some teachers may find this activity to be a good choice to serve as the core for an administrator-observed lesson.

Common Core Info
The Common Core State Standards first reference use of the traditional algorithm for adding and subtracting in the 3rd Grade standards. The 2nd Grade standards explicitly stress the importance of using place value to solve addition and subtraction. This activity addresses the bridge between those standards, helping to ensure that students are prepared to meet the third grade standard.

Use place value understanding and properties of operations to add and subtract.

CCSS.MATH.CONTENT.2.NBT.B.5
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

CCSS.MATH.CONTENT.3.NBT.A.2
Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.

CCSS.MATH.CONTENT.4.NBT.B.4
Fluently add and subtract multi-digit whole numbers using the standard algorithm.

NOTE: The math problems in this presentation do not require regrouping. The concept of subtraction with regrouping is cleverly demonstrated in the PowerPoint, "Lightning Bolt Subtraction." You should check it out!
