# 3-Digit Subtraction Using Place Value Disks — Interactive Slides

Practice subtracting multiples of 100 using place value disks with an interactive drag-and-drop activity.

## New to Using Place Value Disks for 3-Digit Subtraction?

Subtracting with place value disks is a hands-on method of teaching subtraction using physical manipulatives called place value disks. Place value disks represent the different place values in our number system, such as ones, tens, hundreds, etc.

Using place value disks allows students to visually and physically understand the concept of subtraction by manipulating the disks to represent numbers and perform the subtraction operation. Similar to the base ten blocks, the place value disk is an easy-to-use, easy-to-understand option for modeling subtraction with and without regrouping.

## The Perfect Starter Activity for Introducing Place Value Disks

This digital interactive resource is the perfect activity for those first introductions to the world of place value disks. This drag-and-drop interactive provides students with a multitude of opportunities to practice manipulating place value disks to subtract multiples of 100 from three-digit numbers.

With a fun cowboy theme, this interactive activity encourages students to get to know this handy tool by completing the following types of interactions.

• Matching subtraction expressions to their place value disk models
• Modeling and crossing off place value disks to subtract
• Read and determine if statements are true or false in relation to visual subtraction models.
• Writing equations to match place value disk models.
• Solving subtraction word problems using place value disks.
• Writing equations to match 3-digit subtraction word problems.
