SoundsĬomplicated, but it really just means that it is always possible toĬreate an equivalent fraction in the LCM row from the other rows. This button will calculate the LCM based on the rows that have activeĬreate a new wall that contains the originally selected fraction butĪlso a new layer with the number of divisions equalling the leastĬommon multiple of the denominators of the other rows. Multiple' is crucial when adding, subtracting or comparing fractions. In this case all the other layers have bricks turnedĪlso known as 'the lowest common multiple' or 'smallest common If you select the primes wall it is never possible to show an equivalentįraction. Note, this is not always possible, in fact When a brick is clicked the other layers will turn on bricks if they can However if you turn on the equivalent fraction function Normally when you click a brick to turn it on or off, only that brick The 5s also includes a lower wall of 100īricks, this naturally works quite well in explaining percentagesĭecimals (rounded to 2dp), percentages (rounded to 1dp), fractions or
Wall in which the layers are split 1,2,3 up to 12. When you launch this interactive teaching program the initial wall isĪ mixed one showing 3 distinct fraction families. To the right of the wall areīoxes which can be hidden, the value of each box is fraction of the This wall also allows theĭisplay of decimal and percentage values. Each brickĬan be turned on or off by clicking it. Number of bricks and hence each brick represents a fraction whoseĭenominator is equal to the number of bricks in that layer.
