In this file, I have included 42 task cards that cover standards MCC4.NBT.2 and MCC4.NBT.3. Each task card is included with a QR code which will allow students to self check their answers with the appropriate devices! When you scan the code, each one brings up both the question and the answer!
GREAT for reviewing at the end of the year, reviewing at the beginning of 5th grade, or reviewing for standardized testing!!
