2 Digit Addition No Regrouping with Base 10 Blocks for Google Slides
This resource includes 38 interactive Google slides, 4 printable worksheets, and Easel Ready Activity for students to practice adding double digit numbers without regrouping. This math center uses the place value strategy of base 10 blocks to practice solving addition problems with 2 digit addends up to 100.
The interactive slides allow students to drag moveable base-10 blocks into the tens and ones place to model the addition problem.
The resource also includes a blank worksheet template as well as a blank slides template to create additional problems for your students!
The slides and worksheets are divided into two differentiated levels. The first resource allows students to practice adding double digit numbers with sums up to 50 and the second resource allows students to practice adding double digit numbers with sums from 50-100. Each slideshow contains a video link that models how to add double digit numbers using base-10 blocks.
This resource 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.
Students will understand how to add two digit numbers without regrouping using Base-10 blocks.
