Year 1 | Subtracting to Make 10 (Crossing 10) Worksheets

Year 1 subtraction worksheets

Aligned with the maths mastery approach, these differentiated Year 1 | Subtracting to Make 10 (Crossing 10) Worksheets are designed to be used alongside our Year 1 | Subtracting to Make 10 Crossing 10 Lesson Presentation for a complete maths lesson. The maths worksheets require children to use partitioning and ten frames to build up rapid recall knowledge of simple subtractions, first of all making 10, and then using this information to complete the rest of the subtraction.

The worksheets 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 and crossing ten. It focuses on the method of partitioning the second number to subtract to ten and then count back the remaining ones.

Small Steps: Subtraction  – crossing ten (1)

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.
