## Description

Number Pieces helps students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students use the number pieces to represent multi-digit numbers, regroup, add, subtract, multiply, and divide.

Note: Number Pieces Basic, a simplified version of Number Pieces, is also available in the App Store. Number Pieces Basic is designed for primary students. It has fewer features, putting greater focus on place value, counting, addition, and subtraction.

FEATURES

• Add and manipulate pieces (ones, tens, and hundreds).

• Join pieces in groups of ten or break them apart (e.g., 10 ones into 1 ten and vice versa).

• Use the expanding edge piece like a measuring tape to show the dimensions of arrays created with the pieces.

• Choose from three different colors to clearly identify groups or pieces.

• Move, rotate, and duplicate pieces individually or as a group.

• Use the drawing tools to label representations and show understanding.

• Write equations and expressions with the text tool.

• Zoom and scroll to work with larger collections of pieces.

### Great for homeschool

I love this free, ad free app! My kids love using the iPad for school, and this math app gives me access to math manipulative that are expensive and hard to store. They can be used with any math curriculum for a variety of grades. This app is also easy to use, colorful but not distracting.

### Almost perfect

#### Sep 28, 2014

I love having the ability to rotate the base ten blocks, especially when working with division concepts with 2-digit divisors. This is the only virtual manipulative that I have found that has that option! I would love if there was a way to include a thousands cube. This would be especially helpful as we get into decimal place value to the thousandths. Thank you!

Thank you for this great app. I use it with my students and share it during staff development opportunities. Would you please create this same kind of app using place value disks too? Thanks!
