How it works
The fraction wall written in decimals: strips of 0.5, 0.4, 0.3, 0.25, 0.2, 0.125 and 0.1 to drop into five rows, each row showing its total as you build. Two of 0.5 make 1; so do four of 0.25; so do 0.5, 0.25, 0.125 and 0.125. The arithmetic is done in whole thousandths, so 0.1 and 0.2 make exactly 0.3 and never 0.30000000000000004. One whole across or two, a Challenge button that sets a target such as 0.7 or 1.25 for a row to reach, and a note for every strip placed.
