Ant Estimation-Station: Make an estimation station for the children to predict the number of plastic ants in a jar. Put two jars on a tray, one with a specific number (like "30 Ants," for example) and a second jar with a lot more ants. Have the children look at the first jar, compare it to the second, and have them guess the number of ants in the second jar. Have paper-and-pencil for them to write their guesses. For more information about estimation stations see Squish, Sort, Paint and Build, page 216.
