Measurement- Length and Heigth

People measure things for different purposes. Some want to know how long some things are, others what to know how tall.  Pre-K Friends learned what is length. To find out length means to find how long thing is. To measure things we use rulers or measuring tape, but in times when they are not available we can use something else- shoes, feet, or even coins. When we use something besides the ruler, we call it nonstandard units. 

Rachel uses nonstandard units-  pennies to measure the length of a block. There are some rules which friends follow when they use nonstandard measurements.  
1. Use only one kind of items in a time to measure things to get accurate measurements.  For example, in the class we have a box filled with pennies, nickels, dimes and quarters. Friends used only one kind of coins to measure length of blocks.   
2. Start at very beginning and don't leave any space between nonstandard units.

What is height? It is a distance between bottom and the top of a thing.

Leon uses Lego to measure heigth of a chair.
