# Number Pieces, by MLC 4+

• Gratis

## Descrizione

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.

• Hide and reveal work with resizable covers to create your own problems and model strategies.

• Share your work by saving an image or providing a share code to others.

New in Version 4.1:

• Hide and reveal work with resizable covers to create your own problems and model strategies.
• Usability improvements and bug fixes.
______________________

• Share your work by saving an image or url, or providing a sharing code to others. Great for creating the initial setup of an activity, then sharing it with students so they can explore it further.
• Enter text directly from your keyboard with the new writing tool. Add labels, descriptions, or instructional text to your work.
• More easily edit equations and other math text using a traditional text field.
• Drawings on the workspace stay visible when the drawing palette is closed.
