Number Pieces, by MLC vs Area Model

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.

Area Model - Multiplication and Division is an app designed to develop the skills elementary students need to understand and illustrate multiplication and division problems in adherence to the common core state standards. Students benefit from a visual example of the math concept using Base Ten manipulatives. Developed by an elementary teacher and designed by a software developer with years of experience in creating educational software, this innovative, educational app teaches the skills necessary to master multiplication and division. Your student will enjoy learning multiplication and division as they choose animal icons, and bright colors in this interactive math app! FEATURES - Common Core aligned - Base Ten pieces (ones, tens, hundreds) and graph paper - Guided tutorial models how to solve problems - Create your own multi-digit problems for practice - Drawing pad for writing equations. Compare your algorithm to the area model. Choose your pen color. - Icons: choose from five cute animal characters
