Place value within 100 - Counting to 100 - Presentation - Starter

In a Year 1 mathematics presentation, students are encouraged to master place value within 100, with a focus on counting to 100. The starter activity, titled "Fluent in Four - Revision", presents basic subtraction problems that serve as a quick revision of previously learned concepts. For example, students are asked to solve equations such as "18 – 12" and "Eleven – half of six", which are designed to test their understanding of subtraction and the concept of halves within the context of whole numbers.

The lesson continues with exercises that help strengthen the pupils' comprehension of numbers and their relationships. They are prompted to complete sentences that require them to count and write the number of hands and fingers. Additionally, they practice addition by filling in the blanks to create correct equations, further reinforcing their grasp of number bonds and sums. The lesson also includes a practical measurement activity where students determine the combined length of three pencils, with each pencil being the equivalent of five cubes long, allowing them to apply their counting skills to real-world scenarios. The presentation is structured to build confidence and proficiency in basic arithmetic and understanding of numbers within the context of everyday objects.
