This activity shows the child that when quantities are organized it is much easier to see how much you have.

Presentation
- Lay out a rug with two small bowls for counting unit beads
- Take the child to the bead cabinet and start filling a tray with a random amount of units, tens, hundreds, and thousands.
Take the tray to the mat. "What a mess! I wonder how many beads we have here." - Sort the beads into piles by place value.
- Start counting the units.
- When you get to 10 units, have the child exchange them for 1 ten bar.
Place this ten bar with the others. - Count the remaining units (if there are any).
Exchange for ten bars if needed unit until there are fewer the ten units left. - Start counting the tens.
- When you get to ten have the child exchange these for 1 hundred square.
Place this with the other hundred squares. Exchange again if needed until you have fewer than 10 ten bars. - Start counting the hundreds.
- When you get to 10 hundreds, have the child exchange them for 1 thousand cube.
Place this thousand cube with the others. Exchange again if needed until you have fewer than 10 hundreds. - Allow the child to see how easy it is to tell how much you have after exchanging.
