Are your kiddos ready for subtraction with regrouping for 3 digit numbers? How about subtraction across zeros? This is the sweetest product for you!
This unit includes both a color version and a printer friendly version to meet the needs of all classrooms.
As you know, The Common Core Standards require a deeper understanding of numbers and computation and this unit was created with that in mind. This unit require all students to reach to that next level of understanding of subtraction with regrouping.
The following standards are being met in this unit:
2.NBT.B.5: Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
2.NBT.B.7: Add and subtract within 1000, 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. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
2.NBT.B.8: Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.
2.NBT.B.9: Explain why addition and subtraction strategies work, using place value and the properties of operations
Happy Regrouping! I hope your students have the SWEETEST time with this!
