Counting Bags

In Math we have been estimating and counting bigger numbers in our counting books. 

Students choose a bag of random items to take back to their desks. Anything from tokens to bottle caps and toothpicks. First they record what they're counting before making an estimate of how many 'things' are in the bag. Then it's time to count and record. Items are grouped by tens (in cups) and the ones are leftover. 

Example:

3 tens + 4 ones

      = 34
