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.
