Objective
By the end of this lesson, you will be able to apply arithmetic skills to solve Lego challenges and enhance your understanding of basic mathematical operations.
Materials and Prep
- Lego bricks
- Pen or pencil
- Plain paper or notebook
- Ruler
No prior knowledge is required for this lesson. Just bring your enthusiasm and creativity!
Activities
- Build a Lego Tower: Use Lego bricks to construct a tower. Count the number of bricks used and record it in your notebook.
- Addition Challenge: Build another Lego structure and count the number of bricks used. Then, build a second structure and count the bricks used again. Add the two numbers together to find the total number of bricks used.
- Subtraction Challenge: Build a Lego structure and count the number of bricks used. Then, remove some bricks and count the remaining ones. Subtract the number of bricks removed from the original count to find out how many bricks you took away.
- Multiplication Challenge: Build a square or rectangular Lego structure. Measure the length and width using a ruler. Multiply the length by the width to find the total number of bricks needed to cover the entire base of your structure.
- Division Challenge: Build a Lego structure using a specific number of bricks. Divide the total number of bricks by the number of rows or columns to find out how many bricks are in each row or column.
Second Grade Talking Points
- "Arithmetic is the branch of mathematics that deals with numbers and the basic operations of addition, subtraction, multiplication, and division."
- "Addition is combining two or more numbers to find the total. For example, if you have 3 Lego bricks and then you add 2 more, you will have a total of 5 Lego bricks."
- "Subtraction is taking away one number from another to find the difference. For example, if you have 5 Lego bricks and you remove 2, you will be left with 3 Lego bricks."
- "Multiplication is repeated addition. It helps us find the total when we have groups of the same number. For example, if you have 4 rows of 3 Lego bricks each, you can multiply 4 by 3 to find out that you have a total of 12 Lego bricks."
- "Division is the opposite of multiplication. It helps us find out how many equal groups we can make or how many are in each group. For example, if you have 12 Lego bricks and you want to divide them into 4 equal rows, you can divide 12 by 4 to find out that each row will have 3 Lego bricks."
