Students love QR codes because are fun, they get to use technology, and they can check their own work!
This pack aligns to second grade common core place value standards:
2.NBT.1: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones.
2.NBT.2: Count within 1,000; skip-count by 5s, 10s, and 100s.
2.NBT3: Read and write numbers to 1,000 using base-ten numerals, number names, and expanded form.
2.NBT.4: Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
There are 12 QR code cards for each standard. That is 48 cards in all!
You will need a device that can scan QR codes (iPad, smart phone, etc.). You can use the cards without it, but the students will not be able to check their work.
