2nd Grade Odd Or Even Lesson Plan

Topic: Odd or Even

Objectives & Outcomes

• Students will be able to identify whether a group of objects has an odd or even number of members.
• Students will be able to write an equation to express an even number as a sum of two equal addends.

Materials

• A group of objects (up to 20)
• Pencils and paper for each student

Warm-up

• Show the students a group of objects and ask them to count the number of objects.
• Ask the students if they think the group has an odd or even number of members.
• Ask the students to justify their answer by pairing up the objects or counting them by 2s.

Direct Instruction

• Introduce the concept of even and odd numbers and explain that even numbers have exactly 0, 2, 4, 6, 8, or 0 even numbers in between them, while odd numbers have 1, 3, 5, 7, or 0 odd numbers in between them.
• Show the students a group of objects and ask them to count the number of objects.
• Ask the students to identify whether the group of objects has an even or odd number of members.
• If the group of objects has an even number of members, ask the students to write an equation to express the even number as a sum of two equal addends.
• If the group of objects has an odd number of members, ask the students to write an equation to express the odd number as a sum of two addends.(one even and one odd)

Guided Practice

• Give the students a set of objects and ask them to count the number of objects.
• As a class, discuss whether the group of objects has an even or odd number of members.
• Have the students write an equation to express the even number as a sum of two equal addends.
• Have the students write an equation to express the odd number as a sum of two addends.

Independent Practice

• Give the students a set of objects and ask them to determine whether the group has an even or odd number of members.
• Have the students pair the objects or count by 2s to arrive at the answer.
• Have the students write an equation to express the even number as a sum of two equal addends.
• Have the students write an equation to express the odd number as a sum of two addends.

Closure

• Review the definition of even and odd numbers and the equations for even and odd numbers as sums of two equal addends.
• Ask the students to give examples of even and odd numbers.
• Ask the students to explain why adding two equal addends together always results in an even number.

Assessment

• Observe the students during independent practice and provide feedback on their ability to accurately identify even and odd numbers and write equations to express even numbers as sums of two equal addends.
• Have the students complete a quiz or worksheet to assess their understanding of even and odd numbers and their ability to write equations for even numbers as sums of two equal addends.
