Let’s Rock and Roll!

There are three types of rocksThere are three types of rocks

The quicker it hardens the lighter the rock

Once melted thencooled down

Examples:Pumice, granite, obsidian

Starts from magma, then cools and hardens

Igneous

There are three types of rocksThere are three types of rocks

Examples: sandstone,shale, limestone

Found nearbodies of water

layers

Formed over millions of years

The Rock RapThe Rock Rap

Igneous rocks are heated and cooled,

Sedimentary rocks are layered in a pool.

Turn on the pressure,

Turn up the heat,

Metamorphic rocks just can’t be beat.

The Math ConnectionThe Math Connection

• You and a friend go on a rock hunt. You find 15 sedimentary rocks near a creek. Your friend finds 17 rocks. How many tens do you have altogether?

• Write the total number of rocks you and your friend collected in expanded form.

• About how many rocks were collected?

Yes, there’s more math…Yes, there’s more math…

• As you have learned, pumice is the only rock that can float. You really want a piece for your rock collection and buy one from Diamond Dell for $1.05. You also buy another igneous rock, obsidian, for your collection. You paid $1.50. You have $2.60 in your wallet. Do you have enough money? If so, how much change will you receive?
