As part of their learning journey in Mathematics, students in Year 7 have recently been taught how to add and subtract directed numbers using double sided counters. These manipulatives have been really helpful in making this topic visual and interactive, so the students understand how, and more importantly, why we arrive to a particular answer. Students were given a snapshot of this topic during our Year 6 Sampling Day that was held towards the end of the last academic year. It was great to see how so many students still remembered that lesson!
Students were first introduced to the concept of a ‘zero pair’, which is a pair of numbers that when added, equal zero. For example, we have that 1+ (-1) = 0.
Students then completed different calculations involving negative numbers using the counters. They first practised adding directed numbers, then subtracted directed numbers and then a mixture. It was fantastic to see how hard all students worked during this series of lessons.
