Standard Algorithm: Standard Algorithm for Adding and Subtracting Decimals and Whole Numbers

|Subtract across zeros|Decimals | Addition | Subtraction | Whole Numbers | Place Value | Base-Ten Blocks | Word Problems | Real-World Problems | 4.4A | TEK 4.4A | TEKS | Number line | Adding Decimals | Subtracting Decimals | 4th Grade | Fourth Grade | mental math |

This PowerPoint presentation carefully lays out the connection between place value and the standard algorithm to add and subtract whole number and decimals to the hundredths place. Students will understand the steps to the algorithm rather than just memorize the steps without any understanding of why the numbers regroup or decompose.

There are several pictorial models such as base-ten blocks and number lines so students will be able to view the process in many different ways. The animation allows for students to see step by step the concept of borrowing, carrying, decomposing, and/or regrouping.

Students will develop a better understanding of what a decimal is and how the decimal point is used. Real world problems related to Texas History are used and practiced to increase student engagement and mathematical understanding.

Mental math strategies for adjusting the addends in order to make a "friendlier" problem and keeping a constant difference are introduced and practiced. This strategy simplifies difficult problems such as, subtracting across zeros.

The presentation is self directed. Once the presentation has been used in whole group it can be placed in a work station where students can review individually or perhaps see what they missed on a day they were absent.
