# Free 2nd Grade 2.7A Determine Whether A Number Up To 40 Is Even Or Odd Using Pairings Of Objects To Represent The Number Lesson Plan (Math)

## Topic: Determining whether a number up to 40 is even or odd

### Objectives & Outcomes

• Students will be able to determine if a number up to 40 is even or odd by pairing objects to represent the number.

### Materials

• A variety of objects for students to use for pairing (e.g. cards with pictures of animals, small toys, etc.)
• Chart paper or a whiteboard and markers

### Warm-up

• Review the concept of even and odd numbers with students. Ask them to give examples of even and odd numbers and to explain how they know if a number is even or odd.
• As a class, create a list of even and odd numbers up to 20.

### Direct Instruction

• Introduce the concept of even and odd numbers up to 40.
• Show students how to pair objects to represent even and odd numbers up to 40. For example, for the number 20, students can pair up two 10s to make 20.
• Have students practice pairing objects to represent even and odd numbers up to 40.

### Guided Practice

• Show students a number up to 40 and have them determine whether it is even or odd by pairing objects to represent the number.
• Have students work in pairs to find the even or odd status of numbers up to 40.

### Independent Practice

• Have students work independently to find the even or odd status of numbers up to 40.
• Give students a number and have them find the even or odd status of the number using pairings of objects.

### Closure

• Have students share their results with the class and discuss any challenges they faced.
• Review the concept of even and odd numbers and how to determine the even or odd status of a number using pairings of objects.

### Assessment

• Observe students during independent practice to assess their understanding of the concept and their ability to use pairings of objects to determine the even or odd status of a number.
• Have students complete a worksheet or written task that requires them to apply their understanding of even and odd numbers in a variety of situations.
