 Understanding multiplication Work out the missing numbers in multiplication sums F1: 2, 3, 4, 5 and 10 times-tables eg x 5 = 45 F2: Multiples of 10 eg x 30 = 150 F3: 2 to 10 times-tables eg x 8 = 72 F4: Multiples of 10 eg x 80 = 480 F5: Using decimals eg 8 x = 4.8 F6: A variety eg 7 x = 210, 8 x = 32, x 8 = 72 F7: A variety eg x 8 = 72, x 80 = 480, x 0.8 = 4.8, 30 x 60 =

 Random number generator: target board A screenshot of the number generator. F8: A flexible whiteboard resource which generates 24 different sets of numbers; similar to a target board.

The colour of the number can be changed. Select one of 8 colours then click on a number. The numbers can be put arranged in a grid, click this button or arranged randomly, click this button The numbers can be grouped by dragging them about. The numbers can be discarded by dragging them to the bin. Children can use the resource to match pairs: eg 3x5 and 15 (times-tables 1) eg 35 and 70 (doubles) A clock starts when a set of numbers has been generated. The clock can be hidden or shown (click the green clock button). It can be stopped by clicking the 'stop the clock' button! The clock can be used to see who can match the pairs in the quickest time.
