Counting
Say one number for each item in order: 1, 2, 3, 4, 5 Know that the last number reached when counting a small set of objects tells you how many there are in total ('cardinal principle') Count objects, actions and sounds ELG - Verbally count beyond 20, recognising the pattern of the counting system Counting Collections in the Early Years Counting Collections in the Early Years In this article for practitioners, Cath Gripton and Deliah Pawluch explore the 'counting collections' approach, which encourages children to spend time playing and experimenting with counting. A Incey Wincey Incey Wincey In this game, children roll the dice and count how many steps to move the spider up or down the drainpipe. Tidying Tidying When tidying away toys in this activity, children will use their counting skills to check that all the toys are in the box. Number Book Number Book Creating a 'Book of Four' provides an opportunity for children to collect groups of four objects and consider how the groups of objects are similar. Counting Collections Counting Collections In this activity, children choose collections of items to count and are supported as they find ways to keep track of, and record, their counting.
