Complete Number Bonds to 20 Worksheet Downloads That Actually Work

Understanding Number Bonds: What Makes 20 So Special?
This concept of number bond involves number friendships that children need to memorise until they become automatic. When we say 12 + 8 = 20, we're teaching students that 12 and 8 are partners who always add up to 20 together. Once they've got these partnerships memorised, mental maths becomes lightning fast (and their confidence absolutely soars). We have packed quite a lot into these worksheets, covering everything from visual tens frames to quick-fire recall games.
Essential Skills Your Year 2s Will Master Through Number Bond Practice
Teaching number bonds for years has shown us something interesting: children who nail these early become confident mathematicians later on. They stop that finger-counting habit (finally!) and start seeing patterns everywhere in maths. Regular practice with our structured worksheets transforms hesitant calculators into speedy problem-solvers, and the benefits ripple through everything they tackle:
• Lightning-quick mental addition and subtraction in any maths topic
• Rock-solid confidence during those tricky SAT questions
• Natural subtraction strategies (they just "see" that 20 - 13 = 7)
• Better number sense when handling money or measuring activities
• Independence from counting aids and finger-counting methods
Where Do Students Actually Use These Number Skills?
The idea of number bonds to 20 pops up everywhere once you start noticing! We love those moments when children suddenly spot number bonds during PE scoring or while helping with shopping. They'll announce "Mum, you need 3p more for £20!" and feel absolutely chuffed with themselves. These mathematical partnerships show up constantly:
• Working out change when spending pocket money (especially from £20 notes)
• Calculating team scores during sports day and playground games
• Helping with cooking - measuring ingredients and splitting portions
• Reading analogue clocks (working out minutes to the next hour)
• Sharing treats fairly at birthday parties and group activities
• Completing number puzzles and spotting patterns in games
