Number Bonds Fun

Overview

In this 45-minute lesson, 1st grade students will explore number bonds focusing on even and odd numbers. They will work collaboratively to create number bonds involving both even and odd numbers, strengthening their understanding of number decomposition and parity concepts aligned with Common Core standards.

Standards Alignment

Mathematics - Grade 1

• CCSS.MATH.CONTENT.1.OA.B.3: Apply properties of operations as strategies to add and subtract.
• CCSS.MATH.CONTENT.1.NBT.B.2: Understand place value and use it to add and subtract.
• CCSS.MATH.CONTENT.1.OA.C.6: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
  (Focused on number sense, composition/decomposition, and working with even and odd numbers implicitly through addition.)

---

Learning Objectives

By the end of this lesson, students will be able to:

• I can recognize and identify even and odd numbers.
• I can create number bonds using both even and odd numbers.
• I can demonstrate how numbers in number bonds add together to form a whole.

---

Success Criteria

• Students correctly classify numbers as even or odd.
• Students accurately create at least three number bonds including a mix of even and odd numbers.
• Students explain how number bonds add up to the whole number and identify parity in group discussions.

---

Materials Needed

• Number bond templates (large printed sheets)
• Small counters or counting cubes (in two colors for visual aid)
• Whiteboards and dry erase markers (for each student)
• Even and odd number flashcards
• Visual anchor chart with definitions/examples of even and odd numbers
• Dyslexia-friendly number cards (using clear font and spacing)

Lesson Breakdown

1. Introduction (8 minutes)

• Begin with a quick warm-up: display numbers 1-10 and ask, “Who can tell me which are even and which are odd?” Use the anchor chart to reinforce concepts.
• Explain: “Today, we will use what we know about even and odd numbers to make number bonds. Number bonds help us see how numbers split apart and come together.”
• Use I can statements aloud: “I can identify even and odd numbers” and “I can create number bonds.”

2. Guided Practice / Mini Lesson (10 minutes)

• Show a large number bond template on the board with the whole number first (choose numbers 4-10).
• Model creating a number bond with an even and an odd number: e.g., 7 as 4 (even) + 3 (odd).
• Ask students to help you check if numbers are even or odd and discuss why.
• Use counters to physically represent the numbers in the bond.

3. Small Group Work (15 minutes)

• Divide students into groups of 4-5, give each group number bond templates, counters, and flashcards.
• Task: Create three number bonds where the parts include both an even and an odd number, using numbers 5-10.
• Encourage them to discuss with group members which numbers are even or odd and explain their thinking.
• Teachers circulate and ask probing questions (e.g., “How do you know this number is odd?”) and assist as needed.

4. Share and Discuss (7 minutes)

• Bring the class back and invite 2-3 groups to present one number bond they created.
• Encourage students to use complete sentences and mathematical vocabulary (whole, parts, even, odd).
• Reinforce correct reasoning and celebrate all efforts.

5. Independent Exit Ticket (5 minutes)

• Provide each student with a small worksheet: a number bond with the whole number 9 or 10, and ask them to fill in parts including one even and one odd number.
• Students will draw counters/circles to represent the parts and label numbers.
• Collect for formative assessment.

Differentiation

Learner Type	Strategy
Struggling Learners	Use tactile counters and paired teaching; simplify number bond options to 5-6. Use dyslexia-friendly reading cards with clear fonts and spacing. Visual and verbal repetition of “even” and “odd” concepts.
English Language Learners (ELLs)	Use visual aids and gestures to reinforce vocabulary. Pair ELLs with peer buddies and provide sentence frames (e.g., “This number is ____ because it is _____.”).
Advanced Learners	Challenge to create number bonds with larger numbers (11-20) and include two odd or two even numbers as parts. Introduce the term “sum” and encourage explaining addition sentences.
Students with Dyslexia	Provide printed instructions in large, spaced text with dyslexia-friendly font. Use multisensory approaches: counters, spoken instructions, and visual aids. Allow oral responses during the share phase.

---

Extension Activities

• Introduce “number bond stories” where students create short stories to describe how number bonds work using even and odd contexts (e.g., "I have 7 cookies. I gave 4 to a friend and kept 3. Which are even/odd?").
• Build a “number bond wall” where students post their number bonds for ongoing review and reference.

---

Assessment

• Ongoing observation during group activities and presentations.
• Review of independent exit tickets for correct number bonds and even/odd understanding.
• Teacher anecdotal notes on students’ use of math language and accuracy.

This lesson plan encourages engagement through hands-on activities, peer collaboration, and clear conceptual understanding of even and odd number bonds, all firmly rooted in the Common Core framework and mindful of diverse learners’ needs.
