Place value within 100 - Introducing the 100 square - Planning

Year 1 students embark on their Summer term journey into place value, with Week 1 focusing on the use of a 100 square. National Curriculum objectives for this unit include counting to and across 100 both forwards and backwards from any starting point, counting in numerals and in multiples of tens, and identifying one number more or one less than a given number. The unit's key vocabulary includes terms such as 'count', 'tens', 'columns', 'pattern', 'same', 'different', 'one more', and 'one less'. The lesson introduces the 100 square through various resources, including a presentation and tens frames, and encourages children to become familiar with the concept through a series of activities and discussions.

In the class, children will explore the 100 square, starting with locating specific numbers such as 58, and discussing the patterns they observe. They'll engage in paired talk to delve into counting in tens, using a tens frame for reference, and noticing the patterns that emerge in the columns of the 100 square. The lesson also includes activities to find one more or one less than a given number, with emphasis on understanding the meaning behind the numbers and the changes in digits. The lesson plan outlines different expectations depending on the depth of understanding, from beginning to use the 100 square and noticing patterns, to having a secure understanding of counting in tens and the concept of one more or one less. The lesson concludes with reflective questions to ensure students grasp the key concepts and can articulate what they've learned and understood.
