### PRODUCT DESCRIPTION

Everyone knows that Base 10 Blocks are a natural way to get across the concepts of place value for Ones, Tens, Hundreds, and regrouping a Ten into 10 Ones, a Hundred into 10 Tens, and so on.

But actually using them is a little more difficult. These pages have illustrations of Base 10 Blocks and a sequence that guides children through the steps of regrouping, providing them with a template in which to write the problems themselves ensuring that they align the Ones digits.

The Smartboard file has Tens and Ones grouped for each individual problem on a Place Value Mat. The teacher can demonstrate the regroupiing process using exactly the same sequence you want your students to use.

Common Core Standards:

2.NBT.5: “Fluently add and subtract within 100 using strategies based on place value…”

Subjects: Math, Basic Operations, Arithmetic, Place Value

Duration: 8 pages, 2-3 days

A Smartboard 10 file is also included. Click on the .zip file icon, and you can open the PDF, Word, and Smartboard files separately.
