Prancer and Arnie and their friends, Mason and Katie M 3 MAKING MATH MAGIC

Mason and Katie loved to visit their grandparents who live in the country. They could explore the barn, walk in the woods, and play games with Granny and Papaw. But sometimes, they would get lonesome without their friends. They wanted a pet to play with. M 3 MAKING MATH MAGIC

Katie asked her Granny if she could get a pet to keep in the country. Granny said that they could not afford to keep a pet that didn’t help out in some way. They couldn’t feed and take care of a pet that didn’t do something in return… M 3 MAKING MATH MAGIC

Katie thought and thought about a pet that could help around the farm. When she went home, she got on her computer and looked for a helpful pet for sale. M 3 MAKING MATH MAGIC

Finally, she found a pony. His name was Prancer, the Perimeter Pony, and he could measure the length of the sides of the field or the sides of the barn or the sides of the garden. Katie called her Granny to tell her the good news. M 3 MAKING MATH MAGIC

When Katie visited her grandparents the next time, there was Prancer, the Perimeter Pony, out in the field! He pranced around the outside of the field and measured as he went. M 3 MAKING MATH MAGIC

He measured the sides of the field, the barn, the garden, and the garage – he loved to measure the perimeter of everything! Papaw knew how much fencing to buy and Granny knew how much rope to buy because Prancer helped them measure PERIMETER. Granny and Papaw were pleased and Katie was very happy! M 3 MAKING MATH MAGIC

What if Prancer came to your school? How could he help you measure? How many steps do you think it would take Prancer to walk around field #1? How many steps do you think it would take Prancer to walk around field #2? M 3 MAKING MATH MAGIC

Mason liked Prancer, but he felt like this pet really was Katie’s pet and not his. So, he asked Papaw if he could get his own pet. Papaw told him, “Mason, you know the rules. We can’t get any pets that don’t help out on the farm. And, we don’t need another perimeter pony. ” “I know, Papaw, ” Mason said. “I will try to find something else. ” M 3 MAKING MATH MAGIC

So, Mason went home, turned on his computer, and searched for a helpful pet. He looked for a long time before he found the perfect pet – Arnie, the Area Aardvark! M 3 MAKING MATH MAGIC

Arnie wasn’t as perky as Prancer. He didn’t like to do much of anything, but he was very good at plopping down and measuring space. Every time he plopped down, he actually covered up a square unit. Mason couldn’t wait to tell his Granny and Papaw about Arnie the Area Aardvark! M 3 MAKING MATH MAGIC

The next time Katie and Mason went to visit, there was Arnie! He plopped down all over the field, the barn floor, the garage, and the garden. Arnie could measure how many square units were on the inside of different places. Papaw knew how much fertilizer to use and how much concrete to buy and Granny knew how much paint to buy because Arnie could measure AREA for them. Granny and Papaw were pleased, and Mason was very happy! M 3 MAKING MATH MAGIC

What if Arnie came to your school? How could he help you measure? How many times do you think it would take Arnie to plop down and cover up field #1? How many times do you think it would take Arnie to plop down and cover up field #2? M 3 MAKING MATH MAGIC

Prancer the Perimeter Pony and Arnie the Area Aardvark became very good friends. Even though they both could measure, they measured very differently. Prancer pranced around the places Arnie covered. M 3 MAKING MATH MAGIC

Before long, all of the neighbors wanted to borrow Prancer and Arnie to help them measure. Mason and Katie’s mom and dad even let them bring Prancer and Arnie home sometimes to help them measure around their house and yard. M 3 MAKING MATH MAGIC

How many steps do you think it would take Prancer to walk around field #6? How many times do you think it would take Arnie to plop down and cover up field #6? M 3 MAKING MATH MAGIC

How many steps do you think it would take Prancer to walk around the edge of the field #7? How many times do you think it would take Arnie to plop down and cover field #7? M 3 MAKING MATH MAGIC

If we want to put a border around the edge of the bulletin board, who could help us measure that – Prancer or Arnie? If we want to put a rug down in the classroom to cover the floor, who could help us measure that – Prancer or Arnie? M 3 MAKING MATH MAGIC

Compare your field to the fields of your table partners…. Did we all get the same field? If we prance Prancer around our fields, would we all get the same perimeter? M 3 MAKING MATH MAGIC

How many times can Arnie plop on your field? Compare your answer to your table mates… M 3 MAKING MATH MAGIC
