Place Value within 50 - Count in 2s 2 - Presentation

In a series of engaging activities focused on place value within 50, students are encouraged to master the skill of counting in twos. The lesson begins with a simple exercise where students continue a sequence starting from zero, counting in increments of two. This activity not only reinforces their understanding of the number sequence but also prompts them to observe and discuss the emerging patterns. Subsequent activities involve practical examples, such as counting pairs of socks and gloves, to help students visualise and apply their counting skills. They are asked to calculate the total number of items by counting in twos, thereby reinforcing the concept of place value and the importance of grouping in mathematics.

Further exploration of the pattern formed when counting in twos is encouraged through the use of a 50 square grid. Students are tasked with continuing the sequence on the grid and describing the patterns they notice, which helps to deepen their understanding of numerical relationships. Additional exercises include completing number lines by counting in twos and engaging in reasoning tasks that challenge students to count backwards and predict which numbers will be said in a sequence. These activities are designed to build fluency in counting and to promote critical thinking about number sequences and place value. The lesson concludes with independent work where students colour in multiples of two and use tens frames to represent totals, solidifying their grasp of counting in pairs and recognising patterns in place value.
