Sliding Wooden Multiplication Board
A wooden 10 x 10 times-table board with a sliding ruler: slide it to a row, read the answer through the window, and see multiplication as rows of numbers.
Project Overview
A times-table board for the classroom. The grid holds every product from 1 x 1 to 10 x 10, and a sliding ruler runs up and down it. Slide the ruler to a row and the window shows that row of the table, so pupils see multiplication as repeated addition rather than a list to memorise.
It is part of the Creative Kit box.
