					This is a 'Practice' module, consisting of eight programs. The first four programs contain exercises in building unit factors for length, mass, volume and general examples (prices of items, wages and examples from chemistry). A unit factor is built from an equation. You build the factor by clicking on one of the items in the equation and then clicking in a 'Numerator' or 'Denominator' box to place the item at that location. You then click on the 'Judge' button to have your unit factor checked. The last four programs in the module contain exercises that involve your making a unit factor to complete a calculation. You have to work out the numerical value for the answer as well as build the unit factor. Your answer is judged for accuracy/precision and for the correctness of the unit factor you have made. You can always 'Peek' to see the set-up and answer that the program was expecting. Your numerical answer can always be given in decimal or scientific notation.
