# Year 1 | Matching Number Bonds to 20 Activity Cards

## Year 1 addition and subtraction worksheets

Aligned with the maths mastery approach, these Year 1 | Matching Number Bonds to 20 Activity Cards are designed to be used alongside our Year 1 | Making Number Bonds to 20 Lesson Presentation Lesson Presentation and allows children to take part in hands-on practical activities that would be ideal for either continuous provision, or for during dedicated maths lessons. The cards should be clear enough for children to do independently, once the learning has been modelled in the above presentation. These cards are also brilliant for sticking in children’s books alongside photographs, to demonstrate learning and progression. Great for anti-worksheet schools!

Small Steps: Find and make number bonds.

NC Links: Represent and use number bonds and related subtraction facts within 20. * Read, write and interpret mathematical statements involving addition, subtraction and equals signs. *Add and subtract one-digit and two-digit numbers to 20, including zero.

TAF Statements: Working towards: Add and subtract (one digit numbers) explaining their method verbally, in pictures, or using apparatus. Recall at least four of the six number bonds for 10 and reason about associated facts.

Working At: Recall all the number bonds to and within 10 and use these to reason with and calculate bonds to and within 20, recognising other associated additive relationships.

Greater Depth – Use reasoning about number and relationships to solve more complex problems and explain their thinking.

Ready-to-progress criteria:  1NF-1 Develop fluency in addition and subtraction facts within 10

Future applications: Add and subtract across 10.

1AS-2 Read, write and interpret equations containing addition(+), subtraction (-), and equals (=) symbols, and relate additive expressions and equations to real-life contexts.
