Number Pieces, by the Math Learning Center for iOS

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. MORE APPS.
