Time - O'clock and half past - Starter

In the Year 3 mathematics curriculum, a starter activity on time teaches students to identify 'o'clock' and 'half past' times. A revision exercise, titled 'Fluent in Four', challenges students to practise their number sense and calculation skills. For example, they might be asked to calculate the time as '20 past 7' or to add together numbers like '6 hundreds, 9 tens, and 3 ones' with '1 less than twenty-eight tens', leading to sums such as 693 + 279. This exercise is designed to reinforce their understanding of place value and addition.

Another task involves completing part-whole models, where students fill in the missing numbers to complete a set, such as finding the missing part when the whole is 8 and one of the parts is 3. Additionally, comparison exercises require students to use greater than, less than, or equal to symbols to compare quantities represented by base ten blocks. This helps to solidify their understanding of numerical value and comparison. The activity concludes with a sentence completion task, where students must state the number of equal halves, quarters, and thirds in one whole, reinforcing their knowledge of fractions. This comprehensive set of exercises is designed to build a strong foundation in key mathematical concepts for Year 3 students.
