**Base Blocks Addition (NLVM)** These two similar applets use base-ten blocks on a place-value chart. You can form any problem you wish up to four digits. The subtraction model shows the bottom number in red instead of blue. When the top blocks are dragged onto the red blocks, they disappear. Although you can begin in any column, the model forces a regrouping strategy as well as a take-away model for subtraction. Good for reinforcing the traditional algorithms. **Base Blocks Subtraction (NLVM)** These two similar applets use base-ten blocks on a place-value chart.

The site uses explanations with manipulatives to demonstrate the different algorithms. The site is intended for teachers, but also states that parents and students are welcome. **Math Forum (Math Forum)** A part of the Math Forum website that features numerous resources on the computation of whole numbers as well as alternate algorithms such as lattice multiplication. **Rectangle Division (NLVM)** This applet uses an array model to represent any two digit number as a product of two numbers. Remainders are included. **Rectangle Multiplication (NLVM)** This applet nicely models two-digit by two-digit products up to 30 x 30. **Scott Foresman eTools** The eTools software provides several applets, including one that will allow the creation of a rectangle up to 50 by 100 that can be filled in with base-ten blocks the same as would be done with physical blocks (Similar to Rectangle Multiplication). **Whole Number Algorithms and a Bit of Algebra! (GMU)** The purpose of this website is to assist the user in looking at addition, subtraction, multiplication and division of whole numbers connecting the conceptual and procedural understandings. The site uses explanations with manipulatives to demonstrate the different algorithms.
