Number Bonds and Fact Fluency
Automatic recall of pairs of numbers that combine to make target numbers (especially bonds to 5 and 10), and memorization of basic addition and subtraction facts. This represents moving from calculating to knowing, enabling efficient mental mathematics.

Prerequisites
Foundational skill — no prerequisites indexed.
What mastery looks like
Must calculate every combination, no automatic recall
- Counts on fingers for all problems
- No instant recall of any facts
- Relies entirely on counting strategies
Beginning to recall some bonds to 5 automatically
- Knows doubles (2+2, 3+3)
- Recalls some bonds to 5
- Still calculates most combinations
- Uses fingers less frequently
Automatically recalls most bonds to 5, developing bonds to 10
- Instant recall of bonds to 5
- Knows some bonds to 10
- Uses known facts to derive others
- Increasing speed and accuracy
Automatic recall of bonds to 10 and many addition/subtraction facts within 20
- Instant recall of all bonds to 10
- Knows most facts within 10
- Uses bonds to solve problems efficiently
- Beginning facts to 20
Fluent recall of extensive fact repertoire, uses strategically in complex problems
- Automatic recall of facts to 20
- Uses fact knowledge for mental math
- Applies bonds across operations
- Derives unknown facts from known
