Numbers to 10: Reading and WritingActivities & Teaching Strategies
Number bonds are a signature element of the Singapore Math approach, serving as a visual representation of part-whole relationships. At the Primary 1 level, students learn to decompose a whole number into two or more parts and vice versa. This concept is fundamental because it moves away from mechanical counting and toward seeing numbers as flexible entities that can be broken apart and recombined.
Learning Objectives
- 1Identify the numeral and number word for each integer from 0 to 10.
- 2Write the numeral and number word for each integer from 0 to 10.
- 3Explain the concept of zero as representing 'none' or an empty set.
- 4Compare numerals and their corresponding number words for similarities and differences in representation.

Inquiry Circle: Hula Hoop Bonds
Place two small hoops inside a large hoop on the floor. Students use beanbags to show different ways to make a target number, physically moving the 'parts' into the 'whole' to see the relationship.
Prepare & details
How do we write the numeral and the number word for each number from zero to ten?
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Think-Pair-Share: The Missing Part Mystery
One student hides some counters under a cup while showing the total and one part. The partner must explain how they used the known part and the whole to find the hidden 'mystery' part.
Prepare & details
What does zero mean?
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Gallery Walk: Number Bond Posters
Groups create posters showing all possible bonds for a specific number using drawings and number sentences. Students walk around to check if any bonds were missed and leave feedback using sticky notes.
Prepare & details
How are numerals and number words the same or different?
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
These activities are a starting point. A full mission is the experience.
- Complete facilitation script with teacher dialogue
- Printable student materials, ready for class
- Differentiation strategies for every learner
Watch Out for These Misconceptions
Common MisconceptionConfusing parts and wholes
What to Teach Instead
Students may try to put the largest number in a 'part' circle. Use the 'Part-Part-Whole' mat consistently and have students physically move items from the parts to the whole to reinforce the hierarchy.
Common MisconceptionThinking there is only one way to decompose a number
What to Teach Instead
Children might believe 5 is only 2 and 3. Use collaborative investigations where groups compete to find the most 'ways' to break a number down, surfacing options like 4 and 1 or 5 and 0.
Assessment Ideas
Give each student a card with a numeral (e.g., 4). Ask them to write the corresponding number word and draw that many objects. Then, give another card with a number word (e.g., 'zero') and ask them to write the numeral and draw the correct representation.
Display flashcards with numerals 0-10. Ask students to call out the numeral and the number word. Then, display flashcards with number words and ask students to write the numeral on a mini-whiteboard or say it aloud.
Show a picture with zero items (e.g., an empty cookie jar). Ask: 'How many cookies are in the jar? What number word and numeral represent this amount? What does zero mean in this picture?'
Key Vocabulary

Suggested Methodologies
Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
