Aligned with the maths mastery approach, these Year 1 | Subtracting to 20 Without Crossing 10 Worksheets are designed to be used alongside our Year 1 | Subtracting Numbers up to 20 Lesson Presentation for a complete maths lesson. The maths worksheets require children to use their knowledge of number bonds to 10  to complete some simple additions using ten frames. The worksheet can also be cut up and used individually in children’s books to demonstrate knowledge and progression, without the need for a whole worksheet.

Topic: Addition and subtraction to 20

This lesson practises subtracting numbers within 20 without crossing ten. It will recap on the methods of taking away: using counters, part-whole models, and crossing out pictures to find the answer.

Small Step: Subtract (not crossing ten)

NC Links: 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. *Solve one step problems that involve addition and subtraction using concrete objects and pictorial representations , and missing number problems.

TAF Statements: Working towards: Add and subtract one digit number explaining their method verbally, in pictures, or using apparatus.

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

Previous experience: Devise and record number stories, using pictures, numbers and symbols.
