Our math challenge today was “can you draw this image?” Ss were shown an image for 2 secs then had 30 secs to draw it from memory. It created great #mathtalk about geometry and positional language. Thank you @robertsonprog! @TDSBmath @davisville_jps

Cold day = less kids at school… but MORE time for 1on1 support. Today a gr 3 student who was only subitizing was able to learn & demonstrate counting on & counting on from the larger #, through game play! So excited by this movement in skills! @TDSBmath @npersaudLC4 @ldilworth1

We loved playing Race to the Flat! Ss take turns rolling the die, filling their flat (hundreds block) with units, and trading the ones for tens rods to cover the 100 block. First to fill the flat wins! Thank you for the suggestion @FOS6Alvarez @davisville_jps @TDSBmath

To share our learning with the school, we made bar graphs about clean water access. Each group had a different data set including drinking advisories added/lifted and drinking advisories by province. They also found the mean and mode of the data @TDSBmath @davisville_jps
