Math Lesson Plan: Making Arrays 5 x 7 Strong!

Grade Level: 3rd Grade

Time Allotment: 60 minutes

Objective: Interpret products of whole numbers, e.g., interpret 5 x 7 as the total number of objects in 5 groups of 7 objects each (e.g., describe context in which a total number of objects can be expressed as 5 x 7).

Materials:

• Large squares of construction paper (5 different colors)
• Circles or other small cutouts (7 per color)
• Glue sticks
• Markers/crayons
• Worksheet with empty grid of 5 x 7 squares (optional)
• Picture books featuring multiples of 5 and 7 (optional)

Procedure:

Introduction (10 minutes):

• Warm-up Activity: Play a quick counting game. Divide the class into 5 groups. Have each group count aloud by 7s, starting at 1. Discuss how different groups reach the same numbers at different times.
• Present the Problem: Ask, "What if we wanted to count 5 groups of 7 things? How could we do it?" Guide the discussion to introduce the concept of multiplication as repeated addition.

Activity (30 minutes):

1. Building Arrays: Distribute one color of construction paper and 7 circles to each student. Explain they will be making "Arrays" – groups of objects arranged in rows and columns. Instruct them to glue 7 circles in a row on their paper.
2. Expanding Arrays: Ask students to make 4 more rows, each with 7 circles, using new colors of construction paper. Encourage them to count aloud as they glue, adding 7 each time. Emphasize that each row contains 7 objects and there are 5 rows in total.
3. Total Count: Once all arrays are complete, ask, "How many circles do you have in total?" Guide students to count all the circles together (35, which is 5 x 7). Discuss how the multiplication symbol (x) relates to the idea of repeated addition.
4. Application: Provide examples of real-world contexts where 5 x 7 might be relevant. Show picture books with groups of 5 or 7 objects (ladybugs on 5 leaves, 7 penguins in a line). Encourage students to come up with their own scenarios where 5 groups of 7 things are present.

Consolidation (10 minutes):

• Worksheet (optional): Distribute the worksheet with a 5 x 7 grid. Instruct students to color one square for each circle they glued in their array. This reinforces the visual connection between the concrete activity and the numerical representation.
• Reflection: Discuss what students learned about multiplication and how they can use it to solve problems in the real world. Ask questions like, "What other multiplication problems can we make with the numbers 5 and 7?" or "Can you think of other situations where we might need to count 5 groups of something?"

Differentiation:

• For students who need additional support, provide manipulatives like counters or small objects to physically show the repeated addition.
• For advanced students, challenge them to create more complex arrays using different numbers of rows and columns. They can also explore multiplication with other numbers by repeating the activity with different sets of materials.

Assessment:

• Observe students' participation in the activities and discussions.
• Collect and review the completed worksheets (if used).
• Ask students to explain their understanding of multiplication using their own words and examples.

Extension Activities:

• Play multiplication games like "Scoot" or "Bingo" using multiples of 5 and 7.
• Have students create their own picture books or stories that involve multiplication problems.
• Encourage students to find and point out examples of multiplication in their everyday lives, such as on food packaging or advertisements.

By engaging students in hands-on activities and connecting math to real-world contexts, this lesson plan will help them solidify their understanding of multiplication and lay a strong foundation for future math learning.

Note: This plan is a flexible guide and can be modified to fit the specific needs and interests of your students. Feel free to add your own creative touches and make it a fun and engaging learning experience!
