Objective
By the end of this lesson, the student will be able to understand and apply the concept of place value using Legos. They will create different numbers with Legos and explain how each digit represents different values based on its position in a number.
Materials and Prep
- Various Lego bricks in different sizes and colors
- A flat surface to build on
- Optional: A piece of paper and a pencil for notes
Before the lesson, review the basic concept of place value: units, tens, hundreds, etc. Make sure to have enough Lego bricks available for creating numbers.
Activities
-
Building Numbers:
Using the Lego bricks, the student will build different numbers. For example, they can use one large brick for hundreds, ten smaller bricks for tens, and individual bricks for units. Encourage them to create their own numbers and explain them.
-
Place Value Bingo:
Create a bingo-style game where the student has to build a number from a call-out. For instance, if you say "two tens and three units," they would build the number 23 with their Legos.
-
Number Stories:
Have the student create a "number story" using their Lego creations. They can build a number and then come up with a fun story about that number, explaining what each digit represents.
Talking Points
- "What do you think happens to a number when we move a digit to the left? It gets ten times bigger!"
- "Can you show me how many tens are in the number you built? Count the bricks!"
- "Why do you think we use different sizes of bricks to represent different values?"
- "If we have 3 bricks in the hundreds place, what number do we have? That's right! 300!"
- "What happens if we add one more brick in the tens place? Can you build that number?"
- "Can you think of a real-life example where we use place value? Like counting money!"
- "How does building with Legos help you understand numbers better? It makes it fun, right?"
