Aligned with the maths mastery approach, this Year 1 | Subtracting Within 20 by Counting Back Lesson Presentation is fully editable, and is designed for the Year 1 maths curriculum covering the following maths objectives for the autumn term:
Topic: Addition and subtraction to 20
This lesson practises subtracting numbers within 20 without crossing ten. It focuses on the method of counting back along a number line.
Small Step: Subtract by counting back (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.
