I finally got my computer and phone to talk to each other. Which means, finally, I can post pictures of my Sparkies Stars bulletin board.
The story was Abraham and Isaac -- God's promise of nations and peoples as numerous as the stars, all descended from Abraham. Explaining this concept so five-year-olds could remember it seemed like it might require a game.
The sort of game where they have to guess how many stars there are... there were 96 blue stars, 28 stars that I painted with a special paint so they glow in the dark (they loved that), 154 total 3D stars (there are more stars printed on the fabric background)...
and one Abraham standing on a small green hill in the bottom right corner looking on in amazement.
God took Abraham outside and said "Look up at the sky and count the stars -- if indeed you can count them." Then God said to him, "So shall your offspring be." Genesis 15:5
