The child has to recite the grouping for numbers within 10 (10 :1+9, 2+8 .... ; 9: 1+8, 2+7...). I bought a Rummikub, fix a number, say 8, and see who is the fastest to pick the 8 grouping chips (such as 2+6 ). The more the chips one have, he wins.
As far as possible, ask your kid to do the calculation when buying things in shops.
