Unfortunately, the computer will give you each digit one at a time and you won't know what the next number will be. You are not allowed to rearrange any of the digits you have already placed, so think carefully before you lock a number in place! Good luck!

http://pbskids.org/curiousgeorge/games/how_tall/how_tall.html An important part of school readiness is getting kids used to measuring and estimating using standard and non-standard units of measure. For example, kids learn how to use their footsteps to measure the length of a room. This interactive game asks kids to estimate the height of an object using a variety of non-standard units of measure—tires, donuts, and coins.

The goal of this game is to help kids hone counting and estimating skills. Along the way, they are also introduced to the comparative language of "more" and "less" as they help George catch some unruly (but adorable) chicks. This game has three different levels, but the difficulty of tasks within each level is determined by your child's current ability.
