<div>Let <i>K<sub>0</sub></i>(Var<i><sub>k</sub></i>) be the Grothendieck group of varieties over a field <i>k</i>. We construct an exact category, denoted Add(Var<sub><i>k</i></sub>)<sub><i>S</i></sub>, such that there is a surjection <i>K<sub>0</sub></i>(Var<i>k</i>)→<i>K<sub>0</sub></i>(Add(Var<i><sub>k</sub></i>)<sub><i>S</i></sub>).If we consider only zero dimensional varieties, then this surjection is an isomorphism. Like <i>K<sub>0</sub></i>(Var<i><sub>k</sub></i>), the group K<sub><i>0</i></sub>(Add(Var<sub><i>k</i></sub>)<i><sub>S</sub></i>) is also generated by isomorphism classes of varieties,and we construct motivic measures on <i>K<sub>0</sub></i>(Add(Var<i><sub>k</sub></i>)<i><sub>S</sub></i>) including the Euler characteristic if <i>k</i>=<i>C</i>, and point counting measures and the zeta function if <i>k</i> is finite.<br></div>
