Converting between fractions, percentages and ratios, percentages on grids, rate tables from word problems, speed, distance and time (including moving towards each other, moving walkways and average speed there and back), and how long jobs take with more or fewer workers.
Practise matching a fraction to its equivalent percentage, ratio and 'out of' forms: choose all the correct ones. New values every time, with a video.
Practise turning a word problem into a table: saving $15 a month, using 16 boxes a week. Fill the blank cells. New stories every time.
Practise calculating average speed from distance and time, with supercars, cheetahs, lions and whales. New numbers every time, with a solution video.
Practise calculating distance from speed and time, with supercars and fast animals. New numbers every time, with a narrated solution video.
Practise calculating how long a journey takes from distance and speed, with supercars and fast animals. With a narrated solution video.
Practise relative speed: walking with a moving walkway the speeds add, against it they take away. Speeds and times, new every time, with a video.
Practise speed problems where two people move towards each other and a dog runs between them: find the time first. With a narrated solution video.
Practise average speed for a round trip at two speeds: whole distance over whole time, not the two speeds halved. With a narrated solution video.
Practise percentages with shaded grids of 100, 50, 25 and 20 squares: what percentage is shaded, or left blank? A new grid every time.
Practise work and time problems: if 25 artists draw 2 portraits in 5 hours, how long for 8? New workers and tasks every time, with a solution video.
