My students thoroughly enjoy working with QR codes and demonstrating their knowledge in response to these questions.
This set of over 150 QR Codes addresses the following Common Core standards:
5. NBT.2: Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.
5. NBT.4 Use place value understanding to round decimals to any place.
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.
Use the Student Instructions Page 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 mathematics.
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.
