Product Description

What is this?

Included in this file is one instructional PowerPoint teaching students how to add three-digit numbers with and without regrouping using the partial sums strategy.

What is included?

This resource includes several different pieces:

•One PowerPoint Slideshow modeling and practicing how to add three-digit numbers with and without regrouping. The regrouping is introduced gradually- regrouping in the ones place, regrouping in the tens place, and regrouping in the tens and ones place.

•Five practice books with six problems in each book. The books practice addition without regrouping, regrouping in the ones place, regrouping in the tens place, and regrouping in the tens and ones place, and then mixed practice. There are two versions of the books. One has all the boxes as prompts to support students and the other is blank.

•Five homework pages practicing addition without regrouping, regrouping in the ones place, regrouping in the tens place, and regrouping in the tens and ones place, and then mixed practice.

• A parent letter modeling and explaining the importance of adding using partial sums.

•A six problem assessment. There are two versions of the assessment. One has all the boxes as prompts to support students and the other is blank.

•Anchor chart modeling how to add with expanded form. The anchor chart is available as a full sheet or half sheet for students to glue into their math notebooks.

How do I use the PowerPoints?

In order to use these activities, you must have PowerPoint. I do not believe that they can be played on a Mac.

Open the activity in PowerPoint. Some of the PowerPoints are simply slide shows. However, others that require clicking and dragging are different. For these, DO NOT start as a slide show. Simply view the show in Edit Mode and click and drag the pieces to move. When the students are ready to practice the next slide, select the next slide from the window. Please note that these slides must be viewed in Edit Mode. There are explicit teacher instructions included for the PowerPoint to avoid any confusion.

These activities are designed to be projected onto an interactive Smart Board or whiteboard. However, they can be played on any device that can play a PowerPoint presentation. Please note that these activities are not editable in order to be in compliance with the clip artists’ terms of use.
