Activities in this teaching pack include a template to record different numbers that are one less than other numbers to ten to show pieces of rock sold in a seaside shop and a worksheet to play a game to practise subtracting single digit numbers from ten using concrete objects to support calculations.

The interactive presentation gets the children to explore how to use counting on and back to subtract pairs of single digit numbers from ten to show pieces of rock sold in a seaside shop.

This lesson is part of a numeracy scheme of work to get the children to calculate and record the difference between pairs of numbers to ten by counting back to show numbers of items sold in a shop at the seaside. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
