Class Happenings - Numeracy
Kindergarten and year 1 students are developing their understanding of the link between sharing and grouping. The students will understand the concept that fair sharing means all shares are equal. They will discover that the process can be reversed. Students will count in multiples using 100 charts and number lines and, make and count equal groups to solve multiplication and division problems. The students are developing their ability to organise their counters into equal groups and arrays.
Students in 2/3/4 are brushing up on their addition strategies. We began by creating a list of these strategies and discussing why sometimes one is better to use than the other. We discovered that the “make a ten’ strategy is better to use if one of the numbers is close to ten.
We are also practicing subtraction with and without trading. Our favourite activity is Lose a Flat. You start with 100 then roll a die to determine what we subtract, then we need to trade the flat for ten longs, then trade one long for 10 ones so we can complete the calculation. Each subtraction is recorded in maths journals; the answer provides the next number to subtract from.
Year 5/6 students have also revised addition and subtraction strategies. We also played Lose a Flat to show that we need to trade in order to subtract correctly.
5/6 students completed a measurement assessment task for our Numeracy consultant Leonie Anstey, this was taken to our numeracy cluster meeting where western region schools come together and learn. I was very pleased with our assessment results compared with other schools.
