2. Goals: a. Students will understand the difference between even and odd numbers. 3. Objectives: a. Students will be able to determine whether a number is even or odd.

4. Procedure: a. Initiation: i. The students will gather to the carpet area. ii. The teacher will read a book called Even Steven and Odd Todd by Kathryn Cristaldi to introduce the idea of even and odd numbers. This story is about two cousins, named Steven and Todd, who have to spend the summer together despite their differences. Even Steven loves even numbers and wants everything he does to be even. For example, he eats an even number of pancakes for breakfast in the morning and wakes up at an even hour in the day. On the other hand, Odd Todd loves odd numbers and odd things. For example, he wakes up at an odd hour of the day, eats an odd number of pancakes in the morning, and plants an odd number of cactuses in the garden. iii. After reading the book to the entire class, the teacher will have a group discussion. She will put a picture of Even Steven and a picture Odd Todd poster on the board, identify who is who, and label their names. Then, she will ask the students to recall which numbers that Even Steven liked and also which numbers that Odd Todd liked. iv. The teacher will then conclude the read aloud by stating that Even Steven is a person who loves to be fair. When he brings snacks to school, he makes sure that all of his friends get the equal amount. He always wants to hold the same number of items on his right and left hand. On the other

hand, Odd Todd does not live his life fairly. He doesn’t mind if he has more items on one hand and less on the other hand. b. Lesson Development: i. Demonstration of Activity as a Class: The teacher will ask the students to think of a number less than 20 and will select a few of them to state the number out loud. For example, if a student says the number 10. She will count 10 sweethearts and put them on a plate. Then, she will ask the students to predict who the plate belongs to, Even Steven or Odd Todd? After the predictions, the whole class will test to find out who the plate belongs to by placing the sweethearts on the hands of the poster. For example, if the students predicted Even Steven, they will place a sweetheart into each of Even Stevens hands one by one until the plate is empty. At the end, they will count as a class how many sweethearts are on each hand. In this case, Even Steven will have 5 sweethearts on each hand. She will ask the students if their prediction was correct. They should be able to explain that they are correct because Even Steven has to have an equal amount in both hands and he has 5 sweethearts on each hand, so that means it belongs to him. She will do a couple trials of this before she has the students go into pairs to count their own sweethearts. ii. Explain the Activity: “Now it is time for you to count your own sweethearts. You will work in groups of two, so find a partner. I will give each group a plastic bag filled with an unknown number of sweethearts, one plate, and two napkins. You will empty the sweethearts onto the plate,

count them and write the number on the plate. Then you will use your two napkins to share the sweethearts among each other. You will be able to eat the sweethearts only when you both have the same number of sweethearts on each of your napkins.” Students will: 1.

Put the sweethearts on the plate.

2.

Count the number of sweethearts.

3.

Write it on the plate.

4.

Share them among each other evenly on the napkins.

5.

If it is odd, find a way to make it even. (Add an extra sweetheart to someone’s hand)

6.

Each person in the group gets to eat an equal number of sweethearts.

c. Closure: i. After the students are finished, the teacher will have them all come together to the carpet. She will tell the students that they have to give Even Steven and Odd Todd their plates back. She will call each pair or group of

two to come up to the board and decide who their plate belongs to. Each group will bring up their plate and tape it on to either Even Steven or Odd Todd. For example, if one group had 13 sweethearts in the bag that was given to them and wrote the number 13 on their plate, then they would give this plate to Odd Todd because 13 is an odd number. If a group puts the wrong number on the wrong person, then we can work as a group to find the correct answer.

5. Assessment: a. The teacher will give the students a worksheet to complete (attached the worksheet down below). b. The teacher will also provide a coloring sheet where they will color the odd numbers a certain color and even numbers a certain color. (NOT INCLUDED IN ASSESMENT)

c. The teacher will also assign the students a project to do. For the project they will have to relate the concept of odd and even numbers by find something that is even in their life or something that is odd in their life. They can either bring in an item or make an artwork to represent the item. For example, if a student’s birthday is in December, which is the 12th month in the year that is something that is even in his or her life. This student can draw a picture with the word December and explain to the class how it represents something even in their life. Another example is if a student has one dog, that student can bring in a picture of his dog and explain that having one dog is something that represents an odd number in his life. Finally, if a student named Emily has 5 letters in her name, then she can make something that represents this and explain to her friends how this is something that represents an odd number in her life. The students will share these projects with their classmates....
