My students thoroughly enjoy working with QR codes and demonstrating their knowledge in response to these questions.
This set of over 215 QR Codes addresses the following Common Core standards:
5. NBT.3: Read, write, and compare decimals to thousandths.
a. Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).
b. Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
5. NBT.4 Use place value understanding to round decimals to any place.
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.
