🌎 Looking for Planet Worksheets?

Have your students already learned the names of each planet? Maybe you taught your students a catchy way to remember the order of the planets, such as “My Very Excellent Mother Just Served Us Noodles.” If your students are ready to learn another component of space, it may be time to look at inner versus outer planets!

What exactly is an “inner planet”? An inner planet refers to the four planets that orbit within the asteroid belt. These four planets are known as terrestrial planets, or those made of rocks and metal. 

On the contrary, “outer planets” are the four planets that orbit outside of the asteroid belt. These planets are much bigger and are also known as gas giants. 

Teach Starter has created a worksheet where students must determine which planets are considered inner planets and which are considered outer planets. Students will cut out each square with the planet’s picture and name and glue it in the correct column.

An answer key is included with your download to make grading fast and easy!  

Tips for Differentiation + Scaffolding 

For students who need a bit of a challenge, encourage them to write information about each planet on the back of their paper. If students would like to dive further into a particular planet, consider using a book from our Planet Mini-Book Collection.

Invite students who need additional support to reference previous assignments, posters, or anchor charts. Additionally, this activity can be completed in a small group or 1-on-1 setting.
