Lesson 8: Grobby counts a collectionThe main focus for one-to-one counting is to build, strengthen and cement children%u2019s counting skills. To successfully count, children need to be able to say the forward counting words in sequence i.e. one, two, three, four etc. They also need to be able to match the spoken number word to just one object at a time.How many? This is often the question that is posed. How many children are in the class? How many dinner plates on the table? How many sweets have you got? How many people are in the photograph? How many are coming to the birthday party?We all need to be able to answer the question %u2018how many?%u2019Learning outcomes%u2022 We are learning to count collections of objects to determine %u2018how many?%u2019%u2022 We are learning to be systematic when counting, careful not to count the same item twice%u2022 We are learning to count random collections by tagging and recording our answersTo answer this question, we often have to quickly count the items. Sometimes with a small quantity, we can tell by simply looking and knowing e.g. 3. In mathematics teaching, this is referred to as subitising or calculating without counting.In the early stages of learning, children count sets of bricks by touching and setting aside. The final item in the count denotes the total. However, children also need to practise counting sets of objects that cannot be moved e.g. pictures of collections in books, so it is easy to lose count or count the same item more than once.MaterialsA copy of the task sheet per student pairing and 2 sets of 6 bricks.Talk about%u2022 How many cups can you see? (6)%u2022 How many bricks can you see? (7)%u2022 How many flowers can you see? (8)%u2022 How many footballs can you see? (6)%u2022 How many balloons can you see? (9)Explore with the children the idea of finding %u2018how many?%u2019 without counting one-by-one. Suggest tagging each item to be counted with a brick e.g. when counting the footballs, firstly, stand a brick on each football. Count the bricks where standing. Next, gather the bricks standing on a football, click them together and count to discover %u2018how many?%u2019TasksThe students are tasked to count each set of items, by firstly tagging, then counting the tagging bricks and finally, recording the total beside each picture.18
