Objective
By the end of this lesson, the student will be able to understand basic arithmetic concepts related to hail storms.
Materials and Prep
- Pencil and paper
- Counting objects (e.g., small toys, buttons, or pebbles)
No prior knowledge is required for this lesson.
Activities
- Counting Hailstones: Have the student count a pile of hailstones and write down the number.
- Addition with Hailstones: Ask the student to gather two piles of hailstones and count the total number. Help them write a simple addition equation to represent the sum.
- Subtraction with Hailstones: Give the student a pile of hailstones and ask them to remove a certain number. Help them write a subtraction equation to represent the remaining hailstones.
- Sorting Hailstones: Provide the student with a mix of small and large hailstones. Ask them to sort them into two groups based on size.
- Pattern Recognition: Create a pattern using different sizes or colors of hailstones. Have the student continue the pattern by adding the next hailstone.
Talking Points
- "Hailstones are small balls of ice that fall from the sky during a hailstorm."
- "We can count hailstones to see how many there are. Let's count them together."
- "When we have two piles of hailstones, we can add them together to find the total number. Let's write an addition equation."
- "Sometimes we need to take away some hailstones. We can use subtraction to find out how many are left. Let's write a subtraction equation."
- "We can also sort hailstones based on their size. Let's put the small ones in one group and the large ones in another."
- "Patterns are fun to make with hailstones. We can continue a pattern by adding the next hailstone in the same way."
