my ds does number bonds and then moves onto multiplication tables. They do challenges so bronze, silver then gold in number bonds then bronze, silver and gold in multiplication so its a whole school thing. When you have gold multiplication, you then try for platinum which is any times table question answered within 3 seconds - they are doing the platinum as young as year 4 now
Encourage children to use theirs fingers - if holding up three fingers, how many are left (7!). I also used play an echo game with my children i shout a number, they whisper the bond back. The aim is that children will know them off by heart.
