# Year 5 Adding Different Decimal Places

This Year 5 Adding – Different Decimal Places lesson covers the prior learning of adding decimals within 1, adding decimals with the same number of decimal places and rounding decimals to the nearest tenth and whole number, before moving onto the main skill of calculating the adding decimals which have a different number of decimal places.

The lesson starts with a prior learning worksheet to check pupils’ understanding. The interactive lesson slides recap the prior learning before moving on to the main skill. Children can then practise further by completing the activities and can extend their learning by completing an engaging extension task.
