Unit F – Addition Tens and Ones

This maths scheme of work for Key Stage One gets the children to model and illustrate how to add pairs of two digit numbers with multiples of tens and ones and other two digit numbers using concrete equipment, diagrams and informal written calculations. The class can show how to partition numbers to support calculations.
