PRODUCT DESCRIPTION

Introduce or review subtraction with regrouping with this 61-slide PowerPoint! It is designed to teach your students how to solve 2-digit and 3-digit subtraction problems.

The PowerPoint contains the following format:

Slides 1-21: Subtracting 2-digit numbers with regrouping using base-ten blocks. This section features four different problems. It is fully animated so that when regrouping is necessary, a ten flies OFF the screen and is immediately replaced by 10 ones. This allows your students to watch what happens on the screen, and then do the same action with the base-ten blocks on their desk. Also, one of the problems in the middle of this section does NOT require regrouping, teaching students that you must check to make sure regrouping is necessary before regrouping.

Slides 22-28: Subtracting 2-digit numbers on paper without base-ten blocks. The teacher on the PowerPoint gives the students the tip of turning lined paper sideways so that they have columns to work with. Then, five practice problems are presented and completed.

Slides 29-44: Subtracting 3-digit numbers with regrouping using base-ten blocks. This section features 3 different problems. This section is arranged just like the first set of slides (mentioned above) where base-ten blocks are used as models. One of the problems shows students how to subtract across zeroes.

Slides 22-27: MULTIPLICATION AND DIVISION in the order of operations

Slides 45-54: Subtracting 3-digit numbers on paper without base-ten blocks. 5 practice problems are presented and completed.


Check out the preview!! Various problems from each of the four sections described above is included in this preview. WHEN VIEWING THE PREVIEW, PLEASE MAKE SURE YOU ARE VIEWING IT IN SLIDE SHOW MODE. (The slides will not work properly unless you start the slide show.)
