Objective

By the end of this lesson, you will be able to apply arithmetic concepts to solve problems while exploring the world of Sonic.

Materials and Prep

• Pencil and paper
• Calculator (optional)
• Basic knowledge of addition, subtraction, multiplication, and division

Activities

1. Activity: Sonic's Speed

   Write down the top speed of Sonic, which is 767 miles per hour. Ask yourself the following questions:

   • How many miles does Sonic travel in 1 hour?
   • If Sonic runs at his top speed for 5 hours, how far does he go?
   • If Sonic runs at his top speed for 10 hours, how far does he go?
   • What if Sonic runs at his top speed for 24 hours? How far does he go?

   Use the appropriate arithmetic operation to solve each question.

2. Activity: Sonic's Rings

   Sonic collects rings throughout his adventures. Let's imagine he has 100 rings. Ask yourself the following questions:

   • If Sonic gives 20 rings to Tails, how many rings does he have left?
   • If Sonic collects 30 more rings, how many rings does he have in total?
   • Sonic finds a secret stash of 50 rings. How many rings does he have now?

   Use the appropriate arithmetic operation to solve each question.

Third Grade Talking Points

• "Arithmetic is a branch of mathematics that deals with numbers and basic operations like addition, subtraction, multiplication, and division."
• "We can use arithmetic to solve real-life problems, just like we did with Sonic's speed and rings."
• "When we add, we combine numbers together. For example, if Sonic has 5 rings and collects 3 more, he will have a total of 8 rings."
• "Subtraction is the opposite of addition. It helps us find the difference between two numbers. For instance, if Sonic had 10 rings and gave away 4, he would have 6 rings left."
• "Multiplication is a quick way of adding the same number multiple times. If Sonic finds a box with 6 rings and there are 4 boxes in total, he will have 24 rings."
• "Division helps us share or distribute things equally. If Sonic has 30 rings and wants to share them equally with his friends Knuckles and Amy, they each get 10 rings."
