Write numbers 1 to 10 on the bottom of ten lolly sticks.  Roll out some playdough and then stick the lolly sticks (hiding the numbers) into the playdough (or you could use sand).  Ask your child to take out any number.  What number do they have to add to this number to make ten?  This activity could also be used for general addition (take any two sticks and add them together in your head).  You could also make it harder for older children, for example: pick a lolly stick and tell me if the number is prime or square or neither.  Here are more ideas for learning number bonds to ten: https://www.pinterest.com/search/pins/?q=number+bonds+to+ten
