• Jack-o-Light: We use pumpkins to demonstrate that fire needs air to burn. This goes really well with Fire Safety Week and our pumpkin unit. Also, we 'guesstimate' how many pumpkin seeds are in the pumpkin. We roast them afterwards by following a recipe. You can also create a Kids Pix picture of pumpkins.
• The Little Yellow Chicken: The students will be following an integrated unit on "Helping." They will use reading, math, social studies, science, technology, and other areas of study. Students will read, as a group, the book The Little Yellow Chicken by Joy Cowley. The students will be incorporating prediction, prior knowledge, comprehension skills, and language skills for the word family "-ook", the vowel sound "e", and the exclamation mark. The technology to be utilized by the students consists of use of the HyperStudio for math review, Math Software, Graph Club to create a graph of favorite party foods, Inspiration to guide and create graphic organizers for writing, and the Ultimate Writing Machine to create their own version of The Little Yellow Chicken. They will also incorporate color words to practice the Spanish Language.
• A Math Story!: This lesson plan is designed to use a basic third grade math fact as a prompt to write and illustrate a math story. A hands on math activity using math manipulatives will serve as the focus and review for this lesson. A writing activity will serve as a conclusion as well as an assessment for understanding.

Time required for lesson

45 minutes

Materials/resources

• 10 real apples
• felt board or magnetic board divided into three equal vertical sections
• some type of counters that will stick to the board
• two figures that can represent two friends that will also stick to board (example: I used a girl and boy cut-out that would attach to felt board and apple counters that also attached.)
• friendship addition mats. (I made these by using copying paper divided into three equal vertical sections with a marker. Across the top I typed the words Friendship Addition. On the first two sections I used two different animal stamps, one on each side to represent two friends. In the last section I stamped the two friends side by side. You will need some type of small manipulative counters to use with the mats.)

Pre-activities

Students should have an understanding of number value. They should be able to match numbers with the appropriate set.

Activities

1. Begin by telling addition stories. You should ask two students to be volunteers. Give one student three apples and the other student two. Have students stand on opposite ends of the room. Tell an addition story similar to this: “Sarah” has 2 apples. “Johnny” has 3. They are friends. How many apples do they have together? At this point, Sarah and Johnny move to stand beside each other and class counts total number of apples. Change the number of apples each “friend” has and repeat this activity several times.
2. Direct students’ attention to felt board. Place one of the friend cut-outs on one side, and the other in the middle. Place 2 apples under one friend and 3 under the other. Tell an addition story such as: One friend has 2 apples and the other has 3. How many do they have together? Then move the two friends and their apples to the last section of the felt board. Count the total number of apples together. Do this several times changing the number of apples.
3. Divide students into pairs. Give each pair 10 counters and a friendship addition mat. One side of the mat will belong to one friend, and the other to the other friend (represented by the “stamped animals” on the mats). Then read several addition story problems to the class. Example: One friend has two apples (the first friend will place two counters on their section of the mat). The other friend has three apples (the second friend will place 3 apples in their section.) How many apples do they have together? (students will slide their counters to the last section of the mat and count the total number.) Repeat this using different combinations of numbers.
4. Explain to students that today they have learned how to add two sets of things together. This is called addition.
5. Follow-up lessons can teach students how to write addition problems and how to use appropriate vocabulary such as plus, sum, etc. I laminated my friendship addition mats so that students can use wipe-off markers to write the numbers and symbols that make up the problem (5+2=7) underneath the counters. They can write the problem after they have solved it using counters, or they can write problems for each other and then use the counters to find the answer.
6. You can integrate Language Arts by having students give problems and answers in complete sentences.

Assessment

Teacher monitors students working in pairs with addition mats to assess individual understanding of concept. Anecdotal records provide concrete assessment data.
