Notes - Release Edition V1.5 |

In addition
to a new colour scheme, this version sports sound effects, animated
vector graphics which automatically scale to any resolution, and simple
tracking. Clicking the operand toggles between addition, subtraction and multiplication. The material is most powerful in multiplication mode, which has been set to the default value in this version. Children may use the multiplication tables they have memorized already or can repeatedly add multiples of beads while skip counting aloud. i.e. "three, six, nine, exchange, twelve". Narrating the process is also a useful exercise, such as "five times five hundreds is twenty five hundreds, so add three hundreds, exchange, two more hundreds, and twenty hundreds - two thousands". The real value of the large beadframe is in reinforcing multiplication tables while demonstrating the new concept of long multiplication, i.e. a multiplier with more than one digit. Usually the child doesn't note the product generated by each multiplier digit (the partial product) separately until he/she has used the frame for a long time. With a real Montessori large bead frame you could clear it after each partial product, but in this version the microcoaching intelligence accumulates the sum of the products continuously. Auto-exchange,
whereby the frame automatically exchanges groups of ten is not recommended
unless the child is fully capable of exchanging normally. A simpler
question in this case is what is required, rather than too much help.
It is a powerful time saver, though, once the concept is understood. |

Known
Issues:Going back and forth with undo/redo sometimes produces inaccurate tracking, but the frame corrects itself after one step. We have eliminated the answer button--the beadframe checks itself continuously for the answer and plays a sound when the answer is found. It also now tracks the accumulated score in each operation, between sessions, and in total. |
