This set of over 230 QR Codes addresses the following Common Core standard:
5. NBT.7 Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
The Student Instructions Page can be used as a task card for a small group or center. Note that these instructions call for students to use pictures, numbers, or words to demonstrate the process for finding their answers. This method for supporting answers builds off lower grades understanding of problem explanations and is important with decimals because of the relationship to fractions and visual models. This explanation method corresponds with the Common Core Mathematical Practices:
4. Model with mathematic.
5. Use appropriate tools strategically.
6. Attend to precision.
As a teacher you may choose to supplement this set QR Codes with decimal squares, base ten blocks, fraction tiles, and/or calculators.
Included in this document is a table of contents for the QR Codes by topic as well as alignment to Common Core Standards. Please note that QR codes do not have to be printed in color in order to work. In other words, color codes can be printed black and white and should still work without issues. Thank you.
