WHY?

It’s best to introduce subtraction with regrouping using concrete manipulatives related to place value such as base 10 blocks. Using base 10 blocks is an effective way to support students in developing a conceptual understanding of subtraction because they are able to see the value of each digit in the number. This visual model helps students understand the regrouping process of exchanging 1 ten for 10 ones or 1 hundred for 10 tens.

The slides are designed for students to simultaneously model subtraction equations with base 10 blocks and the standard algorithm. Building a correlation between the equation and the physical model will help students build a strong foundation for subtraction as they move on to more advanced skills.  

SAVE TIME and ENERGY creating activities for students with these no prep ready to go math centers. 

*****************************************************************************************************

WHO? Resources in this bundle are designed for 1st, 2nd, and 3rd grade students learning or reviewing subtraction.

Common Core Aligned:

CCSS.MATH.CONTENT.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.

I hope this subtraction with base 10 blocks Google classroom Resource is an effective tool to help your students learn and practice their subtraction skills.

This Double Digit Addition Bundle includes 3 resources with over 100 interactive slides for students to master 2 digit addition with and without regrouping using base 10 blocks to model place value. 

This Bundle includes:

• 2 Digit Addition No Regrouping- Base 10 - Google Slides - Digital Math Centers

  • Sums up to 50
  • Sums up to 100

• Double Digit Addition with Regrouping #1- Base 10 Blocks- Digital Math Center

  • Sums up to 50
  • Sums up to 100

• 2 digit Addition with Regrouping #2- Base 10 Blocks- Google Slides Math Center (sums up to 199)

  • Regroup one time (ones or tens place)
  • Regroup twice (ones & tens place)

Each resource listed above has 2 differentiated levels, for a total of 6 differentiated levels to help your students build confidence with 2 digit addition regrouping up to the hundreds place with 3 digit sums. The interactive slides allow students to drag moveable base-10 blocks into the tens and ones place to model the addition problem. The regrouping resources allow students to exchange tens and ones to model what happens when a number is regrouped in the standard algorithm. 

All of the resources in this bundle can be used in Google Classroom for math centers, independent practice, distance learning, or for small group mini-lesson. In addition, this can be used as a teaching resource for a whole class lesson.  Simply project the Google Slides presentation on the whiteboard, use the moveable pieces to model each problem, and give students the worksheet or place value mat to follow along with the lesson. 

Each Resource includes:

• Easel Ready Activity- (all answer boxes and place value pieces have been added to every problem)
• PDF file with instructions for use
• Link to make copy of Google Slides PowerPoint 1
• Link to make copy of Google Slides PowerPoint 2 
• Link for answer keys to both PowerPoints
• Video instructions (You-Tube video link)
• Example Slide to clarify instructions
• Worksheet version of both PowerPoints
• Blank worksheet template- Create additional practice activities!
• Worksheet Answer Key
• Place Value Mat- put in a plastic sleeve for students to use with a dry erase marker 
• Blank Google Slide Template- Create additional problems!

This activity is just right for  2nd grade students first learning double digit addition without regrouping. It could also be a great resource for 3rd grade students who need some extra practice with regrouping and adding multi digit numbers.

This resource is aligned to the Common Core Standard 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.
