Reflections on some great Math PD
Another PD Day, another blog post to consolidate everything! This afternoon I attended and helped run the OCDSB Math PD Day. Man, do I love a good workshop! And today, I experienced 5 of them. Marian Small - Building Number Sense Marian presented a lot of good questions we can ask students in order to improve their understanding of algebra. Some of my favourite examples were: 1.
