If you don't have that much knowledge on multiples of 4, just multiples in general or if you just don't have enough time or patience to work it out, then don't worry - I have made some cards for each multiple. These flash cards are also good for testing yourself on times tables. Putting it on shuffle and autoplay and testing yourself to see if you can answer the question fast enough is also a fun challenge ;) (If you feel that it takes too long to keep clicking your mouse, use arrow keys and space - it takes much less time) - Don't forget to check out "Multiples of 4 up to 100"!
