How can we determine if a group of objects has an odd or even number of members, and why is this important?
Critical Thinking: Students use logical reasoning to determine if a number is odd or even.
Communication: Students express their understanding through equations.
Responsibility: Understanding the significance of odd and even numbers in real-world scenarios.
How do different strategies (pairing objects, counting by 2s) help us identify if a number is odd or even?
In what real-life situations do we need to know if a number is odd or even?
How can writing equations help us understand and prove if a number is odd or even?
Students can pair objects or count by 2s to determine if a number is odd or even.
Students can write an equation to express an even number as a sum of two equal addends.
Students understand the practical applications of identifying odd and even numbers.
2.OA.C.3 Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
