Measurement Length and Perimeter - Kilometres - Starter

In a mathematics lesson tailored for Year 4 students during the Autumn term, the children engage in a "Fluent in Four" revision activity that aims to consolidate their understanding of various mathematical concepts. The session begins with a calculation exercise where students are asked to express the measurement of a block in both centimetres and millimetres, and then in millimetres alone. The exercise includes a multiplication problem where students are tasked with finding the product of 7 and 4, and then comparing the result of multiplying 4 by 3 with that of 9 by 4. This comparison teaches students to identify the difference between two multiplication outcomes.

Further into the lesson, pupils are introduced to the concept of base 10 as a method for calculating the product of 15 and 4. This hands-on approach helps them visualise and understand multiplication at a foundational level. Additionally, the lesson covers fractions, where students learn the inverse relationship between the size of a denominator and the value of a fraction when numerators are identical. They are prompted to fill in the blanks to complete a statement about this relationship and then use their knowledge to compare fractions by selecting the correct inequality symbol (greater than, less than, or equal to). This comprehensive activity reinforces the students' arithmetic skills, their understanding of measurement units, and basic fraction comparison.
