Objective

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

Materials and Prep

• Pencil and paper
• Animal pictures or figurines (optional)

Activities

1. Animal Addition: Choose two animal pictures or figurines. Write down the number of animals for each and then add the numbers together. For example, if you have 3 elephants and 5 lions, how many animals do you have in total?

2. Animal Subtraction: Choose two animal pictures or figurines. Write down the number of animals for each and then subtract the smaller number from the larger number. For example, if you have 8 monkeys and 3 giraffes, how many more monkeys do you have compared to giraffes?

3. Animal Multiplication: Choose an animal picture or figurine. Write down the number of animals and then multiply it by a given number. For example, if you have 4 pandas and each panda eats 3 bamboo shoots, how many bamboo shoots do the pandas eat in total?

4. Animal Division: Choose an animal picture or figurine. Write down the number of animals and then divide it by a given number. For example, if you have 12 penguins and you want to divide them equally into 3 groups, how many penguins will be in each group?

Fourth Grade Talking Points

• "Arithmetic is a branch of mathematics that deals with numbers and operations like addition, subtraction, multiplication, and division."
• "We can use arithmetic to solve problems related to animals, like counting, comparing, and calculating quantities."
• "Addition is combining two or more numbers to find the total."
• "Subtraction is taking away a number from another number to find the difference."
• "Multiplication is repeated addition, where we add the same number multiple times."
• "Division is sharing or dividing a number into equal parts."
• "We can use arithmetic to solve real-life problems, such as calculating the total number of animals, finding the difference in quantities, or distributing items equally."
