Teacher Overview

Number Pieces is a completely free app that can work on all devices either on the web or through an app. Using it you can manipulate graphics that represent 100, 10, and 1. Use this to work with your child on partitioning numbers and showing them in this visual way.

From here, build up to comparing numbers. Two numbers can be shown visually and this should make it clear why, for example, the number 431 is greater than 99 even though none of its individual digits are greater.

This app is very simple to use. Experiment with the icons and you should find it easy to add and manipulate the on-screen elements.

Publisher's 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.

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 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.

• 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.
