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

This virtual version of our Base Ten Area Pieces is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use laptops, iPads, or Chromebooks.

Number pieces are a key component of Bridges in Mathematics, second edition. Online preview available.

App Features

• Add and manipulate pieces (ones, tens, and hundreds).
• Change the starting set of pieces to a basic or an advanced set.
• Join pieces in groups of ten or break them apart (e.g., 10 ones into 1 ten and vice versa).
• Use expanding edge pieces like a measuring tape to show 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.
• Add equations, expressions, and descriptions with the math text and writing tools.
• Zoom and scroll to work with larger collections of pieces.
• Share your work by saving an image or providing a share code to others.

What has inspired us?

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
