Math U See Beta Instruction Manual - 244

Addition & subtraction for multiple-digit numbers and other topics. Beta builds on the foundation in Alpha by applying students’ mastery of single-digit addition and subtraction to multiple-digit addition and subtraction. One of the stepping stones between these two levels is the concept of place value, which is an important milestone for truly grasping any multiple-digit operation.
