The equals sign (=) means that two things have the same value.
Understanding Equality
Imagine an old-fashioned weighing scale. The equals sign sits in the middle, like the part that holds the scale's arms up. What's on one side of the equals sign must weigh the same as what’s on the other side, like weights on a balancing scale. This idea shows that the two sides are the same, or "equal." According to reference information, many children don't realize this; instead they see an equals sign as an instruction for 'the answer'. However, it truly means "is the same as".
Examples
Here are some examples to help children understand:
- Simple Addition: 2 + 3 = 5 means the value of "2 + 3" is the same as the value of "5".
- Balancing: If you have 4 apples on one side of a scale, you need 4 apples or items that weigh the same on the other side to balance the scale, so 4 apples = 4 apples.
- Different ways to show the same number: 1 + 1 = 2, but also 3-1 = 2, so this shows how 1+1 is the same as 3-1 since both equal 2.
Using Concrete Objects
- Use toys or snacks: Put 3 blocks on one side of the table and 3 blocks on the other, then say "3 blocks is equal to 3 blocks" or use snacks; 2 cookies on one plate is equal to 2 cookies on the other.
- Draw: Draw 4 stars on one side of a piece of paper and 4 stars on the other side. Connect the two sides with the equals sign, and point out that the number of stars is the same.
- Weighing Scale (if available): Demonstrate with small objects, showing how equal weight on both sides keeps the scale balanced.
Why is it Important?
Understanding equals is essential for later math skills. It is a foundation for understanding algebraic equations and mathematical concepts.
Key Takeaways
- The equals sign (=) means "is the same as".
- It shows that whatever is on one side has the same value as whatever is on the other side.
- Think of a balancing scale. What's on one side must be equal to what’s on the other side to balance.
- It's not just about finding an answer, it's about understanding equivalence.
