Objective

By the end of this lesson, you will be able to apply arithmetic skills to solve problems related to dogs.

Materials and Prep

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

Activities

1. Activity 1: Dog Treats

   Imagine you have a bag of dog treats that contains 20 treats. If you give your dog 3 treats every day, how many treats will be left after 5 days?

2. Activity 2: Dog Walks

   Your dog needs to go on a walk for at least 30 minutes every day. If you walk your dog for 45 minutes today and 20 minutes tomorrow, how many more minutes do you need to walk your dog for the rest of the week to meet the daily requirement?

3. Activity 3: Dog Age

   Dogs age differently than humans. If a dog's age is equivalent to 7 human years, how old would a 4-year-old dog be in dog years?

Fourth Grade Talking Points

• "Arithmetic is a branch of mathematics that deals with numbers and calculations."
• "Addition is the process of combining two or more numbers to find the total."
• "Subtraction is the process of taking one number away from another to find the difference."
• "Multiplication is the process of repeated addition. It helps us find the total when we have equal groups of numbers."
• "Division is the process of sharing or dividing a number into equal parts. It helps us find how many groups or how much is in each group."
• "In Activity 1, we used subtraction to find the number of dog treats left after a certain number of days."
• "In Activity 2, we used addition and subtraction to calculate the total walking time needed for the rest of the week."
• "In Activity 3, we used multiplication to convert a dog's age into dog years."
