Multiplication and division - Count in 10s 2 - Starter

In the Year 1 mathematics curriculum, during the Summer Term's second week on the fourth day, students are encouraged to deepen their understanding of counting in tens and basic subtraction. The lesson begins with a "Fluent in Four" revision exercise, where children must solve a subtraction problem, enhancing their arithmetic skills. They are introduced to the concept of tens and ones, learning that '1 ten' is equivalent to the number 10. This foundational knowledge is crucial as they begin to recognise patterns in numbers and understand the base-ten number system.

Students are then presented with visual aids such as a tens frame, which helps them to visualise and count in tens. They are prompted to predict the next number in a sequence and to identify the number represented by a filled tens frame. The lesson includes a comparison activity where students use the phrases 'more than' or 'less than' to compare quantities, reinforcing their understanding of numerical relationships. For example, they learn that '2 tens' is equal to 20 and are tasked with determining whether one quantity is greater or smaller than another. Additionally, they tackle a subtraction problem involving halving, such as finding the result of nineteen minus half of eighteen, which integrates their division skills in a practical context.
