Position and Direction - Symmetric Figure - Starter

In a Year 5 mathematics lesson, students are presented with a series of engaging tasks designed to solidify their understanding of number operations and properties of shapes. The 'Fluent in Four' revision activity challenges students to perform a subtraction involving place value knowledge, where they are given the digits of a number in a non-standard format and must calculate the result after subtracting a value that is '1 less than 76 tens'. Additionally, they are tasked with identifying shapes that have exactly one line of symmetry and no more than four sides, further enhancing their geometry skills.

The lesson also includes a number-based problem where students must work backwards to find an original number before a sequence of additions and subtractions are applied to it. This tests their ability to reverse operations and understand the inverse relationship between addition and subtraction. In another exercise, students must complete a number line involving tenths and then round the numbers to the nearest whole number, which is a practical application of rounding decimals. The arithmetic problems presented in the lesson are designed to be solved mentally, encouraging students to develop their mental maths skills alongside their understanding of place value and symmetry.
