Objective

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

Materials and Prep

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

Activities

1. Activity 1: Calculate Horse Feed

   Ask the student to research and find the average amount of feed a horse needs per day. Then, provide them with a scenario where they need to calculate the total amount of feed needed for a certain number of horses over a specific period of time (e.g., a week or a month). Have them use arithmetic operations to solve the problem and determine the total amount of feed required.

2. Activity 2: Horse Racing Statistics

   Introduce the concept of horse racing statistics to the student. Provide them with a list of race times for different horses and ask them to calculate the average race time. Have them use addition and division to find the average. Then, ask them to compare the average race time of different horses and determine which horse has the fastest average time.

3. Activity 3: Horse Jumping Heights

   Discuss the heights of different horse jumping obstacles with the student. Provide them with a set of jumping heights and ask them to order them from lowest to highest. Then, ask them to calculate the difference in height between each consecutive pair of obstacles. Have them use subtraction to find the differences and analyze the difficulty level of the jumps.

Eighth Grade Talking Points

• "Arithmetic is a fundamental branch of mathematics that deals with numbers and their operations."
• "In this lesson, we will apply arithmetic concepts to solve problems related to horses."
• "By using addition, subtraction, multiplication, and division, we can calculate various aspects of horse care and horse racing."
• "Calculating the total amount of feed needed for a group of horses requires multiplication, as we need to multiply the average feed amount by the number of horses and the duration."
• "To find the average race time of horses, we add up the race times and divide the sum by the number of races."
• "Subtraction helps us determine the differences in height between horse jumping obstacles, which can give us insights into the difficulty of the jumps."
