Place Value• Each number has its own place value• When you group things in bundles od hundreds
and tens you might have some left over, so they need to be placed in the right unit

Place Value
• Sometimes its hard to count using thousands of straws on your desk
• So what can we do to show value in the units without having so many straws? Draw them
• What is the value of this number?
