This standards-based place value unit focuses on the Common Core math standards 2.NBT.7. This asks students to add and subtract 3-digit numbers within 1,000, using place value strategies. There are daily lesson plans, whole group activities, partner practice activities, MATH group centers, exit slips, and assessments.
What’s included in the 5 daily lesson plans:
- Whole group activity
- Partner practice activity
- MATH group: Math writing, Apply new skills, Teacher time, Hands-on math (Teacher time is differentiated learning opportunities for remediation, on-level, and enrichment.)
- Exit slip
–Day 1- Strategy 1- Base Ten Blocks
–Day 2- Strategy 2- Expanded Form
–Day 3- Strategy 3- Open Number Lines
–Day 4- 3-Digit Addition With and Without Regrouping
–Day 5-3-Digit Subtraction With and Without Regrouping
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.
The 2.NBT.7 activities that are included in my short answer, centers, printables, and interactive notebooks are similar, but have all been changed to fit these lesson plans. The short answers have different prompts and are now part of MATH groups, the printables & interactive notebooks have been updated and are used during the ‘Apply new skills’ part of MATH groups.
