How to play

1. Read or Listen: Look at the instructions at the top, or click 🗣️ Read Instructions to hear them read aloud.
   

2. Find the Whole & Part: Look at the top circle (Whole) and the filled-in bottom circle (Part).
   

3. Select Your Answer: Click or tap the missing number on the keypad to complete the bond.
   

4. Check Your Answer: If correct, the dashed circle lights up in green and updates your score! If incorrect, read the hint to see how many more you need.
   

5. Keep Going: Click Next Question ➡️ or wait for the game to auto-advance to keep building your score.

How to use Number Bonds
Number bonds visually show how a number breaks into smaller components and how parts join to form a whole. They consist of three connected circles: one Whole circle linked to two Part circles.

The Core Formula
Part + Part = Whole
Whole - Part = Part

1. Finding the Whole (Addition)
   When both parts are known, add them together to find the missing top circle.
   Given Parts: 4 and 3
   How to solve: Combine the two parts (4 + 3).
   Whole: 7
   

2. Finding a Missing Part (Subtraction)
   When the whole and one part are known, subtract the known part from the whole to complete the bond.
   Given Whole: 10
   Given Part: 6
   How to solve: Subtract the known part from the whole (10 - 6).
   Missing Part: 4
   

3. Decomposing Numbers (Fact Families)
   Every completed number bond generates four related equations, helping students build fact fluency and recognize inverse operations:
   6 + 4 = 10
   4 + 6 = 10
   10 - 6 = 4
   10 - 4 = 6
   

Educational Summary
Target Audience: Kindergarten to 1st Grade (Ages 5–7).
Core Mathematical Concept: Decomposing numbers up to 10 using the Part-Part-Whole model (a core pillar of Singapore Math methodology).
Pedagogical Features:
Multisensory Scaffolding: Integrates audio feedback tones and Web Speech API text-to-speech to support emerging readers and early ELL students.
Targeted Error Feedback: Rather than just marking an answer wrong, the feedback box provides constructive mathematical context (e.g., “You have 6. You need 4 more to make 10.”).
Randomized Non-Repeating Cycle: Cycles through whole numbers 1 to 10 randomly before repeating, ensuring balanced coverage across all single-digit facts.

Teacher’s Guide
Curriculum Alignment (Common Core State Standards)
CCSS.MATH.CONTENT.K.OA.A.3: Decompose numbers less than or equal to 10 into pairs in more than one way.
CCSS.MATH.CONTENT.1.OA.C.6: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.

Classroom Implementation Ideas
Whole-Class Warm-Up: Display the game on an interactive whiteboard/Smartboard. Call students up to select the missing part on the numpad as a 5-minute morning math routine.
Independent Math Center: Station students at tablets or Chromebooks. Have them play 10 rounds to track their accuracy score (e.g., aiming for 8 / 10 or higher).
Fact Family Connection: Pair the digital game with mini-whiteboards. For every completed bond on screen, have students write the full 4-equation fact family (e.g., 6 + 4 = 10, 4 + 6 = 10, 10 - 6 = 4, 10 - 4 = 6).

Differentiation Strategies
For Struggling Learners: Provide physical manipulatives (two-color counters or a ten-frame) alongside the screen so students can physically represent the known part and count up to the whole before entering their response.
For Advanced Learners: Ask students to mentally calculate the inverse subtraction equation before tapping their answer, or challenge them to speed-run 10 correct answers in a row.
