I used groceries to show how much 10% is compared to the 90% we get.
I used two tables. One tables was designated God’s table and the other was our table. I then took groceries and used things with 10 to 12 items in the box. Like a box of fruit snacks; 1 on God’s table and the rest on our table. If there was more than 10 items I then handed them out to the group as an “offering”; something above and beyond my 10%.
It was fun filling up our table with food and passing out “offerings”.
There was a significant difference between the two tables. It really lets you see how much we get versus giving to God.
