Adding and Subtracting Decimals: These 4th Grade Practice Pages for Adding and Subtracting Decimals is the perfect resource for seeing the relationship between the standard algorithm and the use of place value.
This resource supports the following concepts and standards:
*Decimals to the hundredths place
*Use of Multiple Strategies
*Strategy to Subtract Across Zeros (Keeping a Constant Difference)
These practice pages support the 4.4A TEK which states: "Add and subtract whole numbers and decimals to the hundredths place using the standard algorithm." In order to fully understand the standard algorithm students must see the connection it has to place value. In order, to get a deeper understanding, the students will learn multiple strategies for adding and subtracting decimals.
Strategies and Models include:
* Steps for Solving Decimal Problems Using the Standard Algorithm
* Adding and Subtracting Decimals on the Hundredths Grids
* Adding and Subtracting Decimals on the Tenths Grid
* Strategy Based on Place Value
* Using Base-Ten Sketches
* Adding and Subtracting Decimals on a Number Line
A bonus product has been added to the file in response to a buyer's request. This mental math strategy helps students subtract across zeros using mental math rather than regrouping. There is an introductory page which is appropriate for cutting and pasting into a math notebook and a practice page with an answer key.
This product was created as a companion to a PowerPoint the teaches the connection between the standard algorithm and place value. Both resources are sold separately and are also bundled together for a discounted price. If you are interested in the PowerPoint see the products listed below.
