### Lesson List

A pictograph is one type of graph.  It uses pictures called symbols to show information or data.  Every pictograph has a title.  The title tells you what the pictograph is about.

Every pictograph has a Key. The Key tells you how much the symbol is when you count.  This symbol can stand for 1 thing.  It could also stand for 2 things.  It might even stand for 5 things.  The Key tells us how much the symbol is when we count.  For example:

If the Pictograph Key says 1 symbol = 2,

then three symbols  would equal (2+2+2) 6.

If the Pictograph Key says 1 symbol = 5, then four symbols

would equal (5+5+5+5) 20.

It is very important to look at the Pictograph Key before we begin counting so that we get the correct answer.

Sometimes you may see half of a symbol.  In that case, you will need to look at the Key to see how much a whole symbol is worth and then cut that number in half.  For example:

If the Pictograph Key says  = 2,

then half of 2 would be 1.  So  would count as 1.

If the Pictograph Key says  = 2,

then would equal (2+2+1) 5.

Now look at the Pictograph below and answer the questions.  Don't forget to look at the Key before counting!
