This file contains 21 problems that are designed to give students extra practice working on Adding, Subtracting, Multiplying, and Dividing Decimals. I have created this file so that it can be copied double-sided and used as a worksheet, or you can make single-sided copies of the file, cut out the cards, and use them as Task Cards.
In addition, each problem contains a QR Code that allows the students to check their work as they go. This helps to ensure that students are following the proper steps and clears up any misconceptions before they move on to a more difficult problem. The QR Codes are fun and engaging, but allows the students to work independently which makes these problems great for centers.
