At the end of this topic, students will be able to independently use their learning to: add two numbers by breaking apart problems into simpler problems add 3-digit numbers using the standard algorithm add or more numbers using the standard algorithm subtract multi-digit numbers using the expanded algorithm subtract 3-digit numbers using the standard algorithm subtract a 3-digit number from another 3-digit number with one or more zeros by using the standard algorithm use addition and subtraction to justify a conjecture Focus Standards Addressed in this Unit: CC.2.1.3.B.1 place value understanding and properties of operations to perform multi-digit arithmetic Important Standards Addressed in this Unit: N/A Misconceptions: The lesser numbers subtracted at each step all add up to the original number subtracted. As long as the numbers add up, is no wrong way to break apart a number.
